[Appendix B — Research Evidence](#appendix-b-research-evidence) ## Species Profile The profile below records this species' taxonomy, natural origin and lifespan as documented in the cited reference. ### Bearded dragon (Pogona vitticeps) — species profile (taxonomy, geographic range, habitat, physical description, behavior, wild diet, reproduction, lifespan) > Pogona vitticeps has a wide natural distribution in eastern and central Australia. [1] > They are found from the eastern half of south Australia to the southeastern Northern Territory (Grenard 1999). [1] > Pogona vitticeps occupies a large range of habitats from the desert to dry forests and scrublands. [1] > Inland Bearded Dragons are 13 to 24 inches long, including the tail. [1] > They are appropriately named bearded dragons because of their "beard," an expandable throat pouch with spikey scales. [1] > They have a broad, triangular head, round bodies, stout legs, and robust tails. [1] > Color for this species depends on the soil of the region they live in, ranging from dull brown to tan with red or gold highlights (Tosney 1996). [1] > Both sexes have a beard, but males display more frequently, especially for courtship rituals. [1] > The beard turns dark to jet black and inflates during the display. [1] > The bearded dragon may also open its mouth and gape in addition to inflating its beard to appear more intimidating. [1] > Pogona vitticeps are opportunistic omnivores. [1] > They live in areas where food may be hard to find, so bearded dragons are not finicky eaters. [1] > Their stomachs are large to accommodate large quantities of plant matter, insects, and the occasional small rodent or lizard (Grenard 1999). [1] > However, captive indoor dragons do not seem to be seasonal and can breed year round (Grenard 1999). [1] > Females dig a burrow and lay up to 24 eggs per clutch, and up to 9 clutches per year. [1] > It is believed that the "founder stock" of captive bred bearded dragons found outside of Australia today were smuggled out of the country between 1974 and 1990 (Grenard 1999). [1] > Pogona vitticeps is the most commonly found captive bred bearded dragon species. [1] ## Life-Stage Care Young, adult and senior care for this species, drawn from first-hand care pages and veterinary references. ### Reptile — life stage (owner-practical care, Merck Veterinary Manual pet-owner) *All lines in this block are paraphrased derived summaries — non-Open-Access source.* > Offering a variety of foods at each feeding, particularly to younger reptiles, may reduce picky-eating problems. [2] > High-protein commercial diets can drive rapid growth but may cause serious long-term problems such as hyperuricemia. [2] ## Is this pet right for you? - **A desert lizard from Australia:** Pogona vitticeps has a wide natural distribution in eastern and central Australia, occupying habitats from desert to dry forests and scrublands, and is the most commonly kept captive bearded dragon. [1] - **13–24 inches, semiarboreal:** inland bearded dragons are 13 to 24 inches long including the tail; they are semiarboreal and often bask on branches, fence posts and picnic tables. [1] - **Omnivorous and not fussy:** they are opportunistic omnivores with large stomachs for plant matter, insects and the occasional small rodent, and are not finicky eaters. [1] - **Prolific breeders:** females dig a burrow and lay up to 24 eggs per clutch and up to 9 clutches per year. [1] - **Observe, don't over-handle:** reptiles suit adults or older children who enjoy observing them rather than handling them. [2] - **Novice-friendly but demanding:** bearded dragons are perhaps the most popular US pet reptile and do better in larger wooden or fiberglass vivaria than glass tanks, needing broad-spectrum lighting and regular calcium supplementation. [3] ## Daily & Weekly Care Checklist Every day: - **Insect-to-plant balance:** juveniles need about 70% insects and 30% vegetables/fruit, while adults need about 20–30% insects and 70–80% vegetables/fruit. [4] - **Gut-loaded insects:** young dragons need a protein-rich diet of primarily gut-loaded insects (feed insects a nutrient-rich diet before offering). [4] - **Calcium and vitamins:** they need regular calcium and vitamin D3 supplementation, including a calcium supplement with vitamin D and a reptile multivitamin powder. [4] - **UVB and basking:** provide broad-spectrum (UVB 290–300 nm) lighting for vitamin D3 synthesis and calcium regulation; basking lamps are the preferred heat/light source for lizards. [3] [2] - **Check the temperatures:** keep at least two thermometers (cool and warm ends) and measure the temperature just above the substrate where the animal rests to confirm the correct basking temperature. [2] Every week: - **Vary the menu:** offering a variety of foods at each feeding, particularly to younger reptiles, may reduce picky-eating problems. [2] - **Avoid toxic foods:** toxic foods to avoid include avocados, beet greens, spinach and rhubarb. [4] - **Keep it clean:** a simpler substrate is easier to keep clean; newspaper is the preferred substrate for ill reptiles. [2] ## Nutrition The short version: bearded dragons are omnivores whose insect-to-plant ratio shifts with age (juveniles ~70% insects, adults ~20–30%), fed gut-loaded insects with calcium and vitamin D3, plus UVB for calcium regulation. [4] [3] Avoid high-protein commercial diets that can drive hyperuricemia. [2] The quotes below summarise this species' dietary requirements and nutrition-related disease risks, drawn from professional veterinary references. ### Bearded dragon feeding — omnivore; juveniles 70% insects / 30% veg, adults 20-30% / 70-80%; gut-loading; toxic foods *All lines in this block are paraphrased derived summaries — non-Open-Access source.* > Bearded dragons are omnivores needing a balanced diet of insects, vegetables and fruit, with the insect-to-plant ratio changing as they mature. [4] > Juveniles need about 70% insects and 30% vegetables/fruit; adults need about 20-30% insects and 70-80% vegetables/fruit. [4] > Young bearded dragons need a protein-rich diet of primarily gut-loaded insects; gut-loading means feeding insects a nutrient-rich diet before offering them. [4] > Safe feeder insects include crickets, mealworms, hornworms, waxworms, calciworms, roaches and superworms. [4] > Bearded dragons need regular calcium and vitamin supplementation, including a calcium supplement with vitamin D and a reptile multivitamin powder. [4] ### Bearded dragon safe greens & vegetables — omnivore; safe leafy greens, wild plants, foods to limit *All lines in this block are paraphrased derived summaries — non-Open-Access source.* > Bearded dragons are omnivorous, eating live invertebrates ('livefood') and plant matter ('greens'); juveniles need about 65% livefood and 35% greens, while adults over 30 cm need about 40% livefood and 60% greens. [5] > Safe greens include watercress, rocket, chicory, cress and grated butternut squash, plus wild plants such as dandelion, clover and plantain leaves; provide as much variety as possible. [5] > Avoid spinach (it prevents calcium absorption) and limit cabbage or kale (these can affect hormone production); Swiss chard, spinach and beet greens should also be fed sparingly because their oxalates bind calcium and other trace minerals. [5] > Most plant material (80-90%) should be leafy green vegetables and flowers, with only 10-20% fruit; avoid fibre-rich, nutrient-poor light greens such as celery and iceberg or head lettuce. [5] ### Reptile nutrition — UVB-dependent vitamin D3 synthesis and calcium regulation *All lines in this block are paraphrased derived summaries — non-Open-Access source.* > For most active (diurnal) lizards and turtles, UVB light is needed to make vitamin D3, which controls calcium balance. [6] ### Reptile nutrition — calcium:phosphorus ratio and UVB-dependent D3 *All lines in this block are paraphrased derived summaries — non-Open-Access source.* > X-rays often show mineralized or radiolucent tophi in organs and joints (as seen in gout). [7] > Primary visceral gout is urate crystal deposition in organs from chronic hyperuricemia, usually excess dietary protein. [7] > Correcting the diet treats primary visceral gout. [7] > Among reptile metabolic bone diseases, nutritional secondary hyperparathyroidism is the most common. [7] > It stems from poor diet (low calcium-to-phosphorus ratio, vitamin D3 lack) or poor husbandry (no UVB, insufficient heat). [7] > Affected animals are usually fast-growing herbivorous or insectivorous lizards and turtles. [7] > Late-stage findings include hyperphosphatemia and low total and ionized calcium. [7] > Critical cases need fluid therapy, nutritional support, parenteral calcium if hypocalcemic, and phosphate binders if hyperphosphatemic. [7] > Correcting diet and husbandry is the mainstay of successful treatment, with a favorable prognosis especially if the animal is still eating. [7] > *[Paraphrased derived summary — non-Open-Access source.]* UVB light (290–300 nm) is especially important for most day-active lizards and turtles/tortoises (chelonians) for vitamin D3 synthesis and calcium regulation. [3] > *[Paraphrased derived summary — non-Open-Access source.]* Feeding insects a calcium-rich diet and dusting them with a high-calcium reptile supplement just before offering prevents nutritional deficiencies. [3] > *[Paraphrased derived summary — non-Open-Access source.]* Bearded dragons are perhaps the most popular US pet reptile; they need broad-spectrum lighting and their insect-and-plant diet needs regular calcium supplementation to avoid secondary nutritional hyperparathyroidism; they do better in larger wooden or fiberglass vivaria than glass tanks. [3] > *[Paraphrased derived summary — non-Open-Access source.]* It is caused by poor diet (low calcium:phosphorus ratio, vitamin D3 deficiency) or poor husbandry (no UVB light, insufficient heat). [8] > *[Paraphrased derived summary — non-Open-Access source.]* Critical cases need fluid therapy, nutritional support, and injectable calcium if blood calcium is low. [8] > Swiss chard, spinach, and beet greens should be fed sparingly because they contain oxalates that bind calcium and other trace minerals and prevent their absorption, which can lead to nutritional deficiencies. [9] > A calcium powder containing vitamin D3 can be sprinkled on food two to three times per week, but inappropriate supplementation with calcium and vitamins (especially vitamin D3) is a common problem, so follow veterinary guidance. [9] > *[Paraphrased derived summary — non-Open-Access source.]* Metabolic bone disease (MBD) is commonly seen in herbivorous lizards and chelonians and is associated with dietary calcium deficiency, a negative (low) calcium-to-phosphorus ratio, or lack of exposure to ultraviolet UVB radiation. [10] ## Husbandry The home is a terrestrial desert vivarium at 25–32°C and 20–30% humidity with a temperature gradient and broad-spectrum UVB lighting; they do better in larger wooden or fiberglass vivaria than glass tanks. [3] Housing, environment and daily-care essentials for this species. ### Bearded dragon environment — terrestrial desert; POTZ 25–32°C, 20–30% humidity, UVB essential, omnivorous *All lines in this block are paraphrased derived summaries — non-Open-Access source.* > Bearded dragons are terrestrial desert lizards; recommended 25–32°C (77–90°F) at 20–30% relative humidity. [3] > All reptiles, including nocturnal and crepuscular species, benefit from broad-spectrum lighting; unfiltered sunlight is best, with artificial UVB bulbs as a useful alternative. [3] > Humid microclimates are often critical for arid species (e.g. tortoises, leopard geckos) to reduce shell pyramiding and abnormal sheds. [3] > It is a semiarboreal lizard that can be found basking on fallen branches, fence posts and picnic tables (Grenard 1999). [1] > *[Paraphrased derived summary — non-Open-Access source.]* For some species, painting a solid black band 8 inches (20 cm) up from the cage bottom on the glass wall adds a sense of security. [2] > *[Paraphrased derived summary — non-Open-Access source.]* Smaller microhabitats inside the enclosure can raise humidity locally without making the whole cage humid. [2] > *[Paraphrased derived summary — non-Open-Access source.]* The enclosure should offer a temperature gradient spanning the species' preferred range from one end to the other, to keep occupants healthy. [2] > *[Paraphrased derived summary — non-Open-Access source.]* Under-tank heaters should cover no more than 30% of the enclosure floor, letting reptiles move away from the heat; they must be designed for reptile tanks. [2] > *[Paraphrased derived summary — non-Open-Access source.]* Furnishing the enclosure with appropriate cage furniture and hiding spaces helps lower stress and competition. [2] > *[Paraphrased derived summary — non-Open-Access source.]* Infrared panels come in many sizes and can be mounted on the cage roof to radiate heat downward. [2] > *[Paraphrased derived summary — non-Open-Access source.]* Diurnal, highly social species kept in groups need several separate basking (under a heat or UV bulb), feeding, and drinking stations positioned out of sight of dominant cagemates and human observers. [2] > *[Paraphrased derived summary — non-Open-Access source.]* Overcrowding must be avoided to limit stress and competition for food, water, basking spots, and mates. [2] > *[Paraphrased derived summary — non-Open-Access source.]* Many terrestrial, digging, or burrowing species need hiding places such as boxes, logs, rocks, or similar objects. [2] > *[Paraphrased derived summary — non-Open-Access source.]* If reptiles are cohabited, the enclosure must be large enough to give each animal its own perch and/or hiding area. [2] > *[Paraphrased derived summary — non-Open-Access source.]* A simpler substrate is easier to keep clean, which is itself a good reason to choose one. [2] > *[Paraphrased derived summary — non-Open-Access source.]* Newspaper is the preferred substrate for ill reptiles: it is cheap, easy to clean, and makes it easy to spot regurgitated food or droppings. [2] > *[Paraphrased derived summary — non-Open-Access source.]* Most reptiles favor overhead bulbs for basking heat and light, likely because this most closely mimics their natural environment. [2] > *[Paraphrased derived summary — non-Open-Access source.]* Basking lamps are the preferred heat/light source for turtles, tortoises, and lizards. [2] > *[Paraphrased derived summary — non-Open-Access source.]* Suitable basking lights include incandescent bulbs, infrared devices, mercury-vapor lamps (which supply both heat and UV), and ceramic heat emitters. [2] > *[Paraphrased derived summary — non-Open-Access source.]* Combined with a basking lamp, under-tank heaters can supply heat both day and night. [2] > *[Paraphrased derived summary — non-Open-Access source.]* Mercury-vapor lamps make excellent basking lights and also emit some natural-sunlight-type ultraviolet light, which reptiles require for health. [2] > *[Paraphrased derived summary — non-Open-Access source.]* Whatever lamp or heater is used, always measure the temperature just above the substrate where the animal rests to confirm it matches the species' correct basking temperature. [2] > *[Paraphrased derived summary — non-Open-Access source.]* Reptile housing requires a suitable enclosure plus sources of light, heat, and water. [2] > *[Paraphrased derived summary — non-Open-Access source.]* For many lizards, turtles, and tortoises, suitable substrates include potting soil, commercial leaf litter, and modest amounts of sand. [2] > *[Paraphrased derived summary — non-Open-Access source.]* Heat lamps must be used with great caution because overheating is a common hazard. [2] > *[Paraphrased derived summary — non-Open-Access source.]* Heat sources should connect to programmable thermostats that switch heat on or off automatically as the temperature falls too low or rises too high. [2] > *[Paraphrased derived summary — non-Open-Access source.]* Every enclosure should have at least two thermometers — one at the cool end away from the heat, one at the warm end near it — to verify the species' recommended temperature range is maintained. [2] > *[Paraphrased derived summary — non-Open-Access source.]* Under-tank heaters are also useful for lizards and snakes. [2] > *[Paraphrased derived summary — non-Open-Access source.]* Reducing ventilation to hold temperature and humidity is a bad idea and often causes skin and respiratory disease. [7] > Sand, gravel, wood shavings, corn cob material, walnut shells, and cat litter should not be used as substrate because they can cause intestinal impaction if consumed, and cedarwood shavings are toxic to reptiles and must never be used. [9] > Lead and zinc are recognised reptile hazards: lead can come from old paint, ceramic food and water bowls, and lead-based materials, and zinc from some metals, so enclosures should use food-safe, lead-free materials. [9] > Use only non-toxic live or artificial plants in the enclosure; care sheets note artificial plants or live non-toxic plants can provide hiding places. [9] ## Behavior & Training Bearded dragons display their beard as aggression (females too), and while some reptiles are solitary, cohousing is possible only with no more than one male per group to avoid fighting. [1] [2] Socialisation, bonding, play and preventing boredom / behaviour problems. ### Reptile — behavior (owner-practical care, Merck Veterinary Manual pet-owner) *All lines in this block are paraphrased derived summaries — non-Open-Access source.* > Some reptile species are solitary and do better housed alone. [2] > Cohousing same-species reptiles is sometimes possible, but a group should contain no more than one male, since males may fight. [2] > Full-spectrum light, which resembles natural sunlight and contains ultraviolet (UV) rays, improves feeding, activity, and to a lesser extent reproduction in reptiles. [2] > The daily light-dark cycle (photoperiod) influences the behavior and bodily functions of all animals. [2] > Feeding behavior and digestion are tied to environmental temperature. [2] > Humidity, light, food type, and the presence of other animals also shape feeding behavior. [2] > Temperament varies: aggression during mating and feeding is common in some semiaquatic turtles, some skinks and iguanas, and many other lizards and snakes. [2] > Females will, however, display their beard as a sign of aggression also. [1] > *[Paraphrased derived summary — non-Open-Access source.]* Aggressive species may need to be separated at feeding time to prevent injury to cagemates. [2] ## Enrichment & Exercise Toys, foraging, hiding and exercise to prevent boredom. ### Reptile — enrichment (owner-practical care, Merck Veterinary Manual pet-owner) *All lines in this block are paraphrased derived summaries — non-Open-Access source.* > Arboreal (tree-dwelling) species should be given horizontal and vertical branches or other suitable climbing material. [2] > Because of these needs, reptiles suit adults or older children who enjoy observing them rather than handling them. [2] ## When to call a vet NOW Metabolic bone disease and Salmonella are the documented health issues for bearded dragons; the manual advises contacting a species-experienced veterinarian promptly when worrying signs appear. [3] [11] - **If UVB or calcium has lapsed:** nutritional metabolic bone disease (calcium/vitamin D3 deficiency) is common in pet reptiles, and UVB exposure raises calcium levels — if the lighting or supplementation setup has slipped, have a species-experienced vet check the dragon. [11] - **Household Salmonella risk:** bearded dragons can carry Salmonella (a 2024 US outbreak linked 27 cases, mostly children under 5) — restrict reptiles from food-preparation areas, stop them roaming freely, wash hands after handling, and seek medical advice if anyone falls ill after contact. [11] - **If it ate a toxic food:** avocados, beet greens, spinach and rhubarb are listed as toxic foods for bearded dragons — never feed them, and call a vet if any was eaten. [4] ## Health & Disease The recurring themes are nutritional metabolic bone disease from calcium/vitamin D3 deficiency and Salmonella carriage; toxic foods (avocado, beet greens, spinach, rhubarb) must be avoided. [11] [4] Common conditions and their clinical signs, drawn from professional veterinary references. If you notice worrying signs, contact a species-experienced veterinarian promptly. ### Bearded dragon health — diabetes mellitus associated with gastric neuroendocrine carcinomas *All lines in this block are paraphrased derived summaries — non-Open-Access source.* > Endocrine diseases are uncommon in reptiles, but diabetes mellitus has been reported in turtles/chelonians (glucosuria and high blood sugar are the main findings, with polyphagia variable); in bearded dragons it has been linked to gastric neuroendocrine carcinomas, though the cause is often unknown. [8] ### Reptile dysecdysis — abnormal shedding and retained skin *All lines in this block are paraphrased derived summaries — non-Open-Access source.* > Humidity needs are considerably higher while a reptile is shedding (ecdysis). [7] > High humidity has long been seen as essential for many tropical species (e.g. chameleons); but humid microclimates are also often critical for many arid species (e.g. tortoises, leopard geckos) to reduce shell pyramiding and abnormal sheds. [7] ### Reptile husbandry essentials — UVB (290–300 nm) for vitamin D3/calcium, species-specific temperature gradients *All lines in this block are paraphrased derived summaries — non-Open-Access source.* > The temperature figures given are air-temperature gradients. [3] ### Reptile metabolic bone disease — secondary nutritional hyperparathyroidism from low Ca:P / no UVB *All lines in this block are paraphrased derived summaries — non-Open-Access source.* > Secondary nutritional hyperparathyroidism is the most common bone disease seen in reptile practice. [8] > *[Paraphrased derived summary — non-Open-Access source.]* Reptiles with very soft jaw bones cannot chew and must receive liquid food via stomach tube or oral syringe. [2] ## Toxicology & Hazards Substances and environmental hazards to avoid. ### Bearded dragon keeper-practical toxicology & hazards (VCA; Merck Veterinary Manual; ASPCA Pro) > Fireflies (Photinus spp.) contain lucibufagins and are highly toxic to lizards; ASPCA reports death in bearded dragons within 2 hours of exposure, so fireflies must never be fed to bearded dragons. [9] > Avocado contains persin, the toxic principle that causes myocardial necrosis in mammals and birds, with horses and fish also susceptible, so avocado should not be fed to bearded dragons. [9] > Collecting insects from outside or the garden is not recommended, because fertilizers and insecticides present on them may be toxic if fed to bearded dragons. [9] ### Reptile metabolic bone disease (MBD) — calcium deficiency / low Ca:P / lack of UVB; pliable jaws, fractures, shell abnormalities *All lines in this block are paraphrased derived summaries — non-Open-Access source.* > MBD is commonly seen in juvenile reptiles. [10] > *[Paraphrased derived summary — non-Open-Access source.]* Toxic foods to avoid include avocados, beet greens, spinach and rhubarb. [4] ## Breeding & Neutering Neutering / spaying, reproduction and preventing unwanted litters. > The beard of Pogona vitticeps is used for both mating and agression displays. [1] > Inland Bearded dragons reach sexual maturity at 1 to 2 years of age. [1] > Mating occurs in the Australian spring and summer months of September to March.

[13] > **PMID 40958376 (2026, Veterinary ophthalmology)** — An Ocular Manifestation of a Systemic Disease With Encephalitozoon Pogonae in a Juvenile Central Bearded Dragon (Pogona vitticeps). (opening): Objective Encephalitozoon pogonae, a recently identified microsporidian species, has been associated with systemic infections in Central bearded dragons (Pogona vitticeps) manifesting as granulomatous inflammation and vasculitis. Despite the species similarity to Encephalitozoon cuniculi, which causes ocular, neurologic, and renal pathology in rabbits, ocular manifestations of E. pogonae in bearded dragons are underreported. This case report aims to explore the ocular manifestations of E. pogonae in a clinical case and highlight the challenges in diagnosis and treatment of microsporidial infections in reptiles. Animal studied A 6-month-old male central bearded dragon with initial presentation of unilateral blepharoconjunctivitis. Procedures The patient was treated with topical ofloxacin 0.3% ophthalmic solution, systemic nonsteroidal anti-inflammatories (meloxicam), and antimicrobials (ceftazidime). Diagnostic efforts included physical and ophthalmic examination, ocular high-frequency ultrasound (48 mHz transducer), cytological examination of conjunctiva, and histopathological examination with PCR analysis confirming E. pogonae in both liver and conjunctiva. Results Despite treatment, the patient died from hemopericardium. Necropsy demonstrated severe granulomatous inflammation in multiple organs, including the liver, intestines, and ocular structures (conjunctiva and uveal tissue), as well as hypermature cataracts and phacoclastic uveitis, consistent with systemic microsporidiosis. Conclusions This case highlights the potential for an ocular manifestation of a systemic disease caused by E. pogonae, underscoring the importance of considering microsporidial infections in the differential diagnosis of refractory ocular disease in reptiles. The findings also emphasize the challenges in diagnosing and treating these infections. *[CC BY — Open Access, verbatim with attribution.]* [14] > **PMID 41317138 (2026, Veterinary medicine and science)** — Detection of Cryptosporidium and Giardia duodenalis in Reptiles in Thailand. (opening): Cryptosporidium spp. and Giardia duodenalis are significant intestinal protozoan parasites affecting humans and animals worldwide. These infections are transmitted through the faecal-oral route, by contaminated water, food or close contact with infected hosts. The zoonotic risk of transmission from reptiles is considered low; yet, limited research exists regarding Cryptosporidium and Giardia infections in these animals. This study investigated the presence of Cryptosporidium spp. and G. duodenalis in reptile faecal samples from a breeding farm in the Chonburi Province, Eastern Thailand. The test population included 363 iguanas, 50 tortoises, 79 bearded dragons and nine snakes. DNA extraction from faecal samples was performed, followed by nested PCR for Cryptosporidium and G. duodenalis, and all positive samples were sequenced for molecular characterisation. Cryptosporidium and G. duodenalis were detected in 13 and 25 out of 501 faecal samples, respectively. Specifically, seven of 363 iguana samples and six of 79 bearded dragon samples tested positive for Cryptosporidium. Cryptosporidium avium was found in 11 samples, and one sample revealed Cryptosporidium serpentis; the remaining sample could not be identified at the species level. For G. duodenalis, 15 of 363 iguanas tested positive, along with six of 79 bearded dragons, two of 50 tortoises and two of nine snakes. Only G. duodenalis assemblage B was identified in positive samples. This study provides epidemiological information on the infection rate and distribution of species of Cryptosporidium and Giardia in a breeding reptile farm in Chonburi Province, Eastern Thailand, and the findings are discussed in the context of the scientific literature. SUMMARY: This study represents one of the largest surveys on Cryptosporidium and Giardia duodenalis in reptiles. Cryptosporidium avium, typically associated with avian hosts, was the predominant Cryptosporidium species identified in iguanas and bearded dragons. Giardia duodenalis assemblage B, known for its zoonotic potential, was the primary assemblage found in iguanas. *[CC BY — Open Access, verbatim with attribution.]* [15] > **PMID 42198584 (2026, Pathogens (Basel, Switzerland))** — Pathological, Immunohistochemical, and Bacteriological Characterization of Salmonellosis in Bearded Dragons (Pogona vitticeps). (opening): Salmonella spp. is a major zoonotic pathogen. Although reptiles are mostly considered subclinical carriers, clinical disease may develop following immunosuppression. Clinical salmonellosis in reptiles has been extensively reported; however, the condition has been rarely described in bearded dragons ( Pogona vitticeps ). We retrospectively analyzed six cases of salmonellosis in bearded dragons and characterized the pathological, immunohistochemical, and bacteriological findings. Clinical signs and gross findings were mostly non-specific. Histological findings mainly consisted of fibrinonecrotizing enterocolitis (83.3%); necrotizing or granulomatous hepatitis (66.7%); pneumonia including bronchopneumonia or interstitial pneumonia in one case each (33.3%); tubulointerstitial nephritis with tubular necrosis (16.7%); and coelomitis (16.7%). Salmonella enterica subsp. houtenae was cultured in three cases (33.3%), whereas S. enterica subsp. enterica serovar Rissen, S. enterica subsp. enterica serovar Cotham, and S. enterica subsp. diarizonae were cultured in one case each. Intralesional bacteria were detected via immunohistochemistry in kidneys and colon in two cases (33.3%). The predominance of lesions in the intestines and liver likely reflects initial intestinal colonization followed by hematogenous dissemination to the liver. Hepatic lesions are thought to represent different stages along a continuum, progressing from acute necrosis to discrete granuloma formation. Renal and respiratory involvement was infrequent, as reported in other reptile species. Some of the isolated Salmonella subspecies ( S. diarizonae and S. houtenae ) are well-recognized causes of clinical disease in other reptile species but not previously identified in bearded dragons. This study provides a comprehensive pathological, immunohistochemical, and bacteriological characterization of salmonellosis in bearded dragons, thus raising awareness and assisting in the identification of this condition. *[CC BY — Open Access, verbatim with attribution.]* [16] > **PMID 41007981 (2025, Animals: an open access journal from MDPI)** — Systemic CD3+ T-Cell Lymphoblastic Leukemia in a Bearded Dragon (Pogona vitticeps): Clinical, Therapeutic, and Pathological Findings. (opening): A three-year-old male bearded dragon ( Pogona vitticeps ) exhibited acute anorexia. Biochemistry revealed mild hyperproteinemia (88 g/L) and elevated liver enzymes (ALT 60 U/L, AST 272 U/L), while the hematology report showed marked lymphocytosis. The animal had been clinically normal at a routine examination 10 months earlier. Based on the clinical and laboratory findings, acute lymphoblastic leukemia was suspected. Treatment was initiated with methylprednisolone (1 mg/kg PO q24h), marbofloxacin (10 mg/kg IM q24h), and lomustine (80 mg/m 2 PO q14d), calculated according to reptile-specific body surface area formulas. A transient stabilization was followed by sudden deterioration on day 3, characterized by hematemesis and severe respiratory distress, leading to spontaneous death. A complete necropsy including histopathology and anti-CD3 immunohistochemistry revealed disseminated infiltration of neoplastic T-lymphocytes throughout all major visceral organs and confirmed the diagnosis of T-cell lymphoblastic lymphoma/leukemia (L/L). This case represents a rare report of systemic acute lymphoblastic L/L in a bearded dragon and underlies the importance of comprehensive diagnostics in reptiles with non-specific clinical signs and the challenges in the treatment of neoplastic diseases in exotic species. *[CC BY — Open Access, verbatim with attribution.]* [17] ### Evidence cluster — Bearded dragon (Pogona vitticeps) husbandry, health & nutrition (peer-reviewed, Europe PMC) > **PMID 41632107 (2026, Acta veterinaria Hungarica)** — *[Paraphrased derived summary — non-Open-Access source.]* In 36 one-month-old bearded dragons (Pogona vitticeps), dietary supplements with/without artificial UVB showed UVB enhanced calcium (P = 0.0489) and Ca2+ (P = 0.0222); a 24-h fast lowered uric acid (P < 0.0001); age affected total protein (lower in juveniles, P = 0.0016); treatments did not affect weight/length and all remained clinically healthy.

[20] ### Evidence cluster — Bearded dragon (Pogona vitticeps) nutrition (peer-reviewed, Europe PMC) > **PMID 40825569 (2025, GigaScience)** — A near telomere-to-telomere phased genome assembly and annotation for the Australian central bearded dragon Pogona vitticeps. (opening): Background The central bearded dragon (Pogona vitticeps) is widely distributed in central eastern Australia and adapts readily to captivity. Among other attributes, it is distinctive because it undergoes sex reversal from ZZ genotypic males to phenotypic females at high incubation temperatures. Here, we report an annotated near telomere-to-telomere phased assembly of the genome of a female ZW central bearded dragon. Results Genome assembly length is 1.75 Gbp with a scaffold N50 of 266.2 Mbp, N90 of 28.1 Mbp, 26 gaps, and 42.2% GC content. Most (99.6%) of the reference assembly is scaffolded into 6 macrochromosomes and 10 microchromosomes, including the Z and W microchromosomes, corresponding to the karyotype. The genome assembly exceeds standard recommended by the Earth Biogenome Project (6CQ40): 0.003% collapsed sequence, 0.03% false expansions, 99.8% k-mer completeness, 97.9% complete single-copy BUSCO genes, and an average of 93.5% of transcriptome data mappable back to the genome assembly. The mitochondrial genome (16,731 bp) and the model ribosomal DNA repeat unit (length 9.5 Kbp) were assembled. Male vertebrate sex genes Amh and Amhr2 were discovered as copies in the small non-recombining region of the Z chromosome, absent from the W chromosome. This, coupled with the prior discovery of differential Z and W transcriptional isoform composition arising from pseudo-autosomal sex gene Nr5a1, suggests that complex interactions between these genes, their autosomal copies, and their resultant transcription factors and intermediaries determine sex in the bearded dragon. Conclusion This high-quality assembly will serve as a resource to enable and accelerate research into the unusual reproductive attributes of this species and for comparative studies across the Agamidae and reptiles more generally. *[CC BY — Open Access, verbatim with attribution.]* [21] > **PMID 40872255 (2025, Pathogens (Basel, Switzerland))** — Phylogenetic Reclassification of Metarhizium granulomatis and Metarhizium viride Species Complex. (opening): Metarhizium (M.) granulomatis and M. viride have previously been described as pathogens causing hyalohyphomycosis in various species of captive chameleons and bearded dragons ( Pogona vitticeps ). Previous studies yielded different genotypes of M. granulomatis and M. viride based on sequencing of the internal transcribed spacer 1-5.8S rDNA (ITS-1-5.8S) and a fragment of the large subunit of the 28S rDNA (LSU). The aim of this study was to clarify the relationships between these genotypes and obtain a more accurate phylogenetic classification by sequencing two different loci of the RNA polymerase II second largest subunit (NRPB2), referred to as RPB1 and RPB2, and the translation elongation factor 1 alpha (EF1α). A total of 23 frozen isolates from 21 lizards, including the first isolates of M. granulomatis and M. viride from Parson's chameleons ( Calumma parsonii ), were available for phylogenetic analysis. A total of 13 isolates belonged to the M. granulomatis complex and 10 isolates belonged to the M. viride complex. Following the amplification and sequencing of the protein-coding genes, the resulting nucleotide sequences were analyzed, trimmed and assembled. These were further analyzed with regard to differences in single-nucleotide polymorphisms (SNPs) and amino acid structure. In consideration of the results of the present analyses, a phylogenetic reclassification is recommended. Three different genotypes of M. granulomatis can be distinguished, which can be phylogenetically addressed as subspecies. Six subspecies can be distinguished regarding M. viride. *[CC BY — Open Access, verbatim with attribution.]* [22] ### Bearded Dragon nutrition: peer-reviewed evidence (Europe PMC) > **PMID 40839529 (2025, MMWR. Morbidity and mortality weekly report)** — Reoccurring Salmonella Cotham Outbreak Linked to Pet Bearded Dragons - United States, 2024. (opening): In April 2024, CDC's PulseNet identified a cluster of seven Salmonella Cotham cases from five states. Isolates were highly related by whole genome sequencing (WGS), and one patient reported contact with a pet bearded dragon. CDC initiated a multistate investigation and as of December 10, 2024, an additional 19 cases had been identified, for a total of 26 confirmed cases from 13 states; state public health partners identified one probable case in an additional state for a total of 27 cases. Eighteen of 25 cases (72%) were among persons who reported contact with a bearded dragon or lizard. Children aged <5 years, especially infants, were disproportionately affected, accounting for 17 (65%) of the 26 confirmed cases; most had bearded dragons in the home without direct animal contact. WGS of two bearded dragon specimens collected in 2024 and three bearded dragon specimens collected during 2012-2014 confirmed genetic relatedness of this rare Salmonella strain and continued circulation among commercially sold bearded dragons. CDC implemented a One Health approach in response, working with pet industry representatives to disseminate information about biosecurity best practices to bearded dragon suppliers and retailers. Investigators contacted a common bearded dragon supplier identified in the traceback investigation to share biosecurity and prevention recommendations. CDC used social media and a website investigation notice to inform the public, recommending that caregivers prevent young children from indirect reptile contact by restricting reptiles from roaming freely, separating reptiles and supplies from food preparation areas, and washing hands and changing clothes after handling reptiles and before holding infants.
