Abstract (opening): Fecal glucocorticoid metabolites (FGM) are widely used to assess hypothalamic-pituitary-adrenal (HPA) activity in vertebrates, but their applicability to reptiles, and more specifically to snakes, remains poorly explored. The objective of the present study was to determine how changes in housing conditions, from a standard racking system to enriched terraria, affect fecal glucocorticoid metabolite concentrations as a proxy potentially related to endocrine activity and stress response. A total of 58 fecal samples were collected across three different phases from 12 snakes representing four species: <i>Boa constrictor</i> (BC), <i>Lampropeltis polyzona</i> (LP), <i>Pantherophis guttatus</i> (PG), and <i>Python regius</i> (PR). FGM concentrations ranged from 54.9 to 832.2 ng/g, with a mean value of 298.4 ± 171.6 ng/g (mean ± SD). Data showed marked inter-individual variability, while within-individual concentrations remained relatively stable across experimental phases. PG exhibited the highest FGM concentrations during the study, with LP showing intermediate levels and PR and BC the lowest. The results showed that housing conditions did not have a significant effect on FGM concentrations in the studied population. In conclusion, the present study showed that fecal hormone analysis provides an integrated measure of glucocorticoid metabolites concentrations over time, potentially reflecting physiological differences among snake species.\n  Source: https://pubmed.ncbi.nlm.nih.gov/42193776/\n- **PMID 41793465 (2026, Parasitology research)** — Single oral-dose fluralaner treatment against Ophionyssus natricis infestation - a large scale study demostrating long-term efficacy in captive snakes.. Abstract (opening): The hematophagous mite Ophionyssus natricis, vector of several viral and bacterial diseases in snakes, is one of the most challenging pathogens for snake breeders. The high environmental resistance of its larval stage makes repeated treatment of the animals unavoidable, while eradication of the mites from enclosures requires extensive cleansing and disinfection, often involving chemical products with known toxicity. The use of ectoparasiticides of the family of isoxazoline have recently proved effective against both adult and larvae of O. natricis, nevertheless data for fluralaner remains limited, particularly in large cohorts. In this study, 1579 snakes representing 18 different species were treated orally with a liquid formulation of fluralaner (Exzolt®) at 2.5 mg/kg, administered either by injection into the prey prior to feeding or via gastric gavage. Mite detachment and mortality occurred within 5 h, and no reinfestation was observed during subsequent 6-months follow-up period, despite the absence of environmental treatments. No side effects were reported in any treated animals, and no negative impact was observed on oviposition or hatching rate. The prolonged efficacy observed in this study further supports its suitability as a minimally invasive yet highly effective treatment of O. natricis infestations in snakes, given the long half-life of fluralaner already documented in mammals.\n  Source: https://pubmed.ncbi.nlm.nih.gov/41793465/\n- **PMID 42071908 (2026, Animals : an open access journal from MDPI)** — Composition and Legal Aspects of Reptiles and Amphibians Displayed at an Exotic Pet Fair in Warsaw (Poland).. Abstract (opening): The global exotic pet trade has expanded in recent decades, raising concerns related to animal welfare, biodiversity conservation, and compliance with international regulations. Reptiles and amphibians constitute a major component of this trade, yet information on species availability and trade practices at exotic pet fairs remains limited. The primary aim of this study was to identify the reptile and amphibian species offered for sale at an exotic pet fair in Warsaw, Poland. Secondary objectives were to assess the declared origin of the animals and the availability of information regarding their legal and conservation status. Photographic documentation of all exhibition tables was used to record species identity, number of individuals, and labeling practices. In total, 818 individuals representing 74 species from 31 families were recorded. Reptiles, particularly squamates, dominated the assemblage, while amphibians accounted for a smaller proportion of the animals offered. More than half of the individuals were labeled as captive-bred, whereas only a small fraction were identified as imported or wild-caught; however, information on origin was absent for nearly half of the animals. Over 50% of the recorded species were listed in Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora, yet no visible information on legal or conservation status was provided at the point of sale. These findings indicate that inconsistent labeling limits transparency and informed decision-making by buyers.\n  Source: https://pubmed.ncbi.nlm.nih.gov/42071908/\n- **PMID 41753677 (2026, Microorganisms)** — Preliminary Screening for &lt;i&gt;Ophidiomyces ophidiicola&lt;/i&gt; in Pet Snakes from Italy and Exploratory Evaluation of Droplet Digital PCR Assay.. Abstract (opening): <i>Ophidiomyces</i><i>ophidiicola</i>, the agent of ophidiomycosis, has recently been reported in wild snakes in Italy, but the status of captive populations remains unknown. We carried out an opportunistic survey of pet snakes from private collections and, in parallel, performed an exploratory evaluation of a droplet digital PCR (ddPCR) assay adapted from an established probe-based real-time PCR. Non-invasive skin swabs were collected by 32 private owners from 97 snakes, representing 31 species across ten Italian regions. All swabs tested negative for <i>O. ophidiicola</i> by both methods, including samples from four snakes that showed cutaneous lesions at the time of sampling. Both assays yielded consistent amplification up to the 1:1000 dilution (ddPCR 0.38 to 0.94 copies/µL for the culture-derived control and 0.24 to 0.33 copies/µL for the field-derived control at 1:1000), while ddPCR retained positive partitions in some replicates at higher dilutions (up to 1:8000). These results provide preliminary screening data for <i>O. ophidiicola</i> in an opportunistic sample of Italian pet snakes and suggest potential applicability of ddPCR as a complementary tool for low-template diagnostics, while highlighting the need for larger, standardised surveys and formal assay validation.\n  Source: https://pubmed.ncbi.nlm.nih.gov/41753677/\n- **PMID 42100220 (2026, Frontiers in veterinary science)** — Advancing evidence-informed practice in modern zoos: research priorities for animal welfare, conservation, and social legitimacy.. Abstract (opening): Modern zoos operate at the intersection of conservation responsibility, ethical accountability and scientific advancement, while facing increasing public scrutiny and rising expectations for transparency and measurable impact. This scrutiny often focuses on animal welfare and the justification for maintaining wild animals in captive environments. Consequently, there is a growing need for zoo-based research to move beyond often anecdotal practice toward robust, evidence-informed decision-making. Evidence refers to systematically collected data and critically evaluated research used to inform management strategies that promote the zoo's key aims. This article synthesises key areas in which contemporary zoo operations rely on limited or untested evidence and identifies priority research questions critical to the future legitimacy and effectiveness of zoos. The paper explores several interlinked themes: the welfare implications of reproduction and breeding management; the role of social bonds in welfare, stress resilience, and translocation outcomes; the underrepresentation of nutrition within animal welfare research; the impacts of human-animal interactions involving both staff and visitors; the maintenance of species-specific behaviours and behavioural diversity in ex situ managed populations; and the relationship between animal welfare, visitor experience, and a zoo's social licence to operate. These themes were identified through persistent assumptions in zoo practice, gaps in the empirical literature, and increasing societal expectations for transparency, ethical justification, and measurable outcomes. Across these areas, the paper highlights a recurring challenge: management practices are frequently justified on theoretical or historical grounds rather than validated, applied outcomes, and conclusions from single studies are often overinterpreted despite limited replication or contextual relevance. Our article therefore emphasises the importance of defining credible evidence, critically appraising published research, and adopting replicated, collaborative multi-institutional and mixed-methods approaches. By outlining these research priorities, this paper provides a framework for advancing zoo-based science that can directly inform management decisions, improve animal welfare outcomes, strengthen conservation impact, build public trust and thus future-proof the zoo industry. Ultimately, we argue that the future success of zoos depends on aligning ethical practice, rigorous research, and meaningful visitor engagement through transparent, evidence-driven approaches.\n  Source: https://pubmed.ncbi.nlm.nih.gov/42100220/\n- **PMID 41773901 (2026, Journal of virology)** — Experimental infection of carpet pythons (&lt;i&gt;Morelia spilota&lt;/i&gt;) with sunshinevirus.. Abstract (opening): Sunshinevirus was originally isolated in 2008 from a collection of Australian pythons suffering an outbreak of neuro-respiratory disease. Sunshinevirus infection cases, including chronic asymptomatic infections, have subsequently been detected throughout Australia by PCR testing. To investigate the association between sunshinevirus infection and disease, controlled experimental infection studies in carpet pythons (<i>Morelia spilota</i>) were undertaken. The study aims were to determine if there was a causal relationship between sunshinevirus and disease, as well as collecting information on potential virus transmission routes, infectious doses, target organs for viral replication and pathology, and incubation period. Between August 2016 and February 2018, six pythons were inoculated with sunshinevirus, two were sham inoculated as control animals, and two were co-housed with infected animals. All animals were sampled weekly and sunshinevirus was detected in virus-inoculated animals by PCR 6-14 days post-inoculation. Five of the six virus-inoculated carpet pythons developed neuro-respiratory disease, and sunshinevirus could be re-isolated from liver and kidney tissues as well as blood. One of the co-housed pythons became infected, consistent with natural transmission. The other co-housed python remained uninfected. Clinical signs commenced 3-7 months after viral exposure. They were slow to develop, often subtle, and predominantly neurological. Histologically, there was a non-suppurative encephalomyelitis, with the most consistent finding being vacuolation and gliosis in the brain. Cytoplasmic inclusions were found in a range of predominantly epithelial tissues. Infected pythons shed infectious virus 2.5-7 months before they showed obvious clinical signs of disease and remained viremic (for several months) until euthanasia.<h4>Importance</h4>Australian pythons are extensively kept in captivity. Since the 1990s, native Australian snakes with neuro-respiratory signs of disease, sometimes fatal, had been presenting to veterinarians in Australia. Research conducted at Murdoch University on some of these snakes resulted in the discovery of a novel virus, now named sunshinevirus (Sunviridae). Widespread follow-up PCR testing of pythons throughout Australia linked sunshinevirus infection to both asymptomatic virus-carriers and pythons showing signs of disease. Experimental infections were conducted to determine whether sunshinevirus infection caused disease in Australian pythons. The experiments demonstrated a causal relationship by fulfilling Koch's postulates, and 5/6 infected animals developed neurological disease. Infected pythons shed virus persistently for months, but control animals remained uninfected. Our findings provide veterinarians with valuable information for the management of sunshinevirus in zoos and private collections.\n  Source: https://pubmed.ncbi.nlm.nih.gov/41773901/\n- **PMID 42514655 (2026, Veterinary sciences)** — Effects of a Single Intramuscular Dose of Rasburicase on Plasma Uric Acid Concentrations in Fasted and Fed Ball Pythons (&lt;i&gt;Python regius&lt;/i&gt;).. Abstract (opening): <b>Background:</b> Hyperuricemia is a common problem in captive reptiles and is associated with gout and renal disease. Rasburicase is a recombinant urate oxidase that converts uric acid into allantoin, a more water-soluble metabolite. This study evaluated the safety and efficacy of rasburicase in clinically healthy ball pythons (<i>Python regius</i>). <b>Methods</b>: Eight adult ball pythons were included in a prospective crossover study. Six experimental conditions were evaluated: fasting with and without rasburicase (0.2 mg/kg IM), feeding with a day-old chick with and without rasburicase, and feeding with a mouse with and without rasburicase. Plasma uric acid concentrations were measured at 0, 24, 48, 72, and 96 h. <b>Results</b>: Rasburicase did not significantly affect fasting uric acid concentrations. Feeding increased plasma uric acid concentrations, with peak values occurring between 24 and 72 h. Following chick consumption, rasburicase promoted a faster decline in UA concentrations, although differences were not significant (<i>p</i> = 0.907). Following mouse consumption, rasburicase significantly reduced UA concentrations (<i>p</i> = 0.002), with a mean reduction of 37.85%. No changes were observed in behavior, appetite or defecation. <b>Conclusions</b>: Rasburicase was well tolerated and reduced postprandial uric acid concentrations in ball pythons.\n  Source: https://pubmed.ncbi.nlm.nih.gov/42514655/\n- **PMID 42154891 (2026, Brazilian journal of biology = Revista brasleira de biologia)** — Determination of the candidate gene responsible for BEL (Blue Eye Leucistic) expression in the ball python (Python regius).. Abstract (opening): The ball python, scientifically known as Python regius, is a popular exotic pet due to its beautiful colors and patterns. One of the most famous characteristics of the ball python is the white coloration seen in the blue-eyed leucistic (BEL) variant. This study indicates that the endothelin receptor type B (EDNRB) gene is a candidate gene responsible for the white color and blue eyes characteristic of the BEL. The results from quantitative PCR (qPCR) show an 11.83% difference in the cycle threshold (Ct) values between the wild type and the platinum complex group. This finding suggests that both alleles in the wild type carry normal EDNRB genes, while the platinum complex group shows that one of its alleles possesses a normal EDNRB gene, indicating a heterozygous condition. Notably, there were no qPCR products detected in the BEL, implying that it lacks a normal EDNRB gene. This is the first finding demonstrating that the EDNRB gene is the candidate gene which responsible for the BEL phenotype.\n  Source: https://pubmed.ncbi.nlm.nih.gov/42154891/\n- **PMID 41927739 (2026, Scientific reports)** — New host record of Amblyomma pakhtunensis on the Indian Pangolin (Manis crassicaudata) with detection of a distinct Borrelia lineage.. Abstract (opening): Pangolins are mammals of the order Pholidota, with most species listed as endangered or critically endangered. They are distributed in both Asia and Africa, with the Indian pangolin (Manis crassicaudata) found in South Asia, including Pakistan. The tick genus Amblyomma, in the family Ixodidae, is widely distributed in tropical and subtropical regions and infests a variety of terrestrial and semi terrestrial vertebrates. The bacterial genus Borrelia is Gram-negative and consists of three main groups, one of which is mainly linked to reptiles, some birds, and mammals. This study focuses on investigating the Indian pangolin as a potential host for Amblyomma pakhtunensis, a recently described tick species previously reported only on monitor lizards and with no known microbial associations. It also aims to determine whether ticks from pangolins contain Borrelia species and assesses their phylogenetic relationships. Ticks collected from a pangolin were morphologically identified as A. pakhtunensis. DNA from a subset of ticks was extracted to confirm their molecular identity and to detect Borrelia spp. in these ticks using conventional PCR. For the former, a partial fragment of tick 16S rRNA was targeted, while for the latter, partial fragments of the Borrelia 16S rRNA, flaB, and glpQ genes were targeted for amplification. A single live pangolin, conventionally identified as M. crassicaudata, was found. Twenty‑seven ticks were collected (16 males, 11 females), all morphologically identified as A. pakhtunensis. BLAST analysis of A. pakhtunensis 16S rDNA sequence showed 99.75% identity with the same tick species. BLAST analysis of Borrelia 16S rDNA and flaB sequences revealed highest identities of 99.25% and 95.91%, respectively, with Candidatus Borrelia javanense. The overall Borrelia infection rate was 50% (5/10), with infections detected in 4/5 female ticks and 1/5 male tick. In both 16S rDNA and flaB based phylogenetic analyses, the detected Borrelia species clustered with Candidatus B. javanense from China. In addition to expanding the vertebrate host diversity of A. pakhtunensis, this study also expands knowledge of the third group of Borrelia by extending their known vertebrate host range and genetic diversity. This study can enhance our understanding of the regional epidemiology of tick-borne diseases and may specifically aid pangolin conservation strategies by taking into account the control of ticks and their associated pathogens.\n  Source: https://pubmed.ncbi.nlm.nih.gov/41927739/\n- **PMID 41317138 (2026, Veterinary medicine and science)** — Detection of Cryptosporidium and Giardia duodenalis in Reptiles in Thailand.. Abstract (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.\n  Source: https://pubmed.ncbi.nlm.nih.gov/41317138/\n- **PMID 41908419 (2026, ACS omega)** — Microarchitecture of &lt;i&gt;Python regius&lt;/i&gt; Scale Surface: A Natural Strategy for Bacterial Adhesion Prevention.. Abstract (opening): Microscale surface structures on natural materials can provide unique functional properties, <i>inter alia</i>, for biological defense. Here, we report that the dorsal scales of ball python (<i>Python regius</i>), feature regularly distributed sharp microprotrusions (spikes) that may serve as a model surface for topography-driven prevention of bacterial adhesion and biofilm formation. The chemical composition and microarchitecture of the skin grain and flesh sides were characterized by Fourier Transform Infrared (FTIR) spectroscopy and scanning electron microscopy (SEM), confirming a keratin-rich, highly organized outer surface bearing dense arrays of spikes with micrometer-scale height and spacing. SEM imaging further corroborated markedly reduced colonization of the spike-bearing dorsal scale surface. Quantitative biofilm assays based on standard colony-forming unit (CFU) enumeration were performed using the newly developed scale-pair model. Relative to the smooth polystyrene reference, <i>Escherichia coli</i> and <i>Staphylococcus aureus</i> attachment and subsequent biofilm formation decreased by 88 and 78%, respectively, after 48 h of incubation in 37 °C. Other cultivation experiments ruled out chemical effects of any residual antimicrobial substances on the skin on bacterial growth, demonstrating that the topography alone mediates inhibition. These findings indicate that <i>P. regius</i> scale microstructures may function as a passive antimicrobial defense, and could inspire biomimetic, antibiofilm materials for biomedical and industrial applications.\n  Source: https://pubmed.ncbi.nlm.nih.gov/41908419/\n- **PMID 42032687 (2026, BMC veterinary research)** — Species-specific variations in corticosterone concentrations in captive snake shed skins: implications for housing systems and welfare.. Abstract (opening): <h4>Background</h4>Captive reptiles may experience stress related to environmental conditions, and housing design is considered a key factor influencing their welfare. This study assessed corticosterone concentrations in shed skins as a non-invasive biomarker of chronic stress in three commonly kept snake species-Boa imperator, Python regius, and Pantherophis guttatus-maintained either in low-stimulus rack systems or enriched terraria. Shed skins were collected from privately owned snakes and from a breeders, prepared following standardized protocols, and analyzed using ELISA assays. Non-parametric statistical methods (Mann-Whitney U tests) were applied due to non-normal data distribution.<h4>Results</h4>Variation in corticosterone concentrations was observed among the studied species, with higher values recorded in P. guttatus compared to B. imperator and P. regius. The effects of housing conditions differed between species. In P. regius, individuals kept in enriched terraria exhibited higher corticosterone concentrations than those housed in rack systems, whereas the opposite pattern was observed in P. guttatus, where snakes maintained in rack systems showed elevated corticosterone levels. No clear housing-related differences were observed in B. imperator. Species-specific relationships between enclosure volume and corticosterone concentration were identified, with positive associations in P. regius, negative associations in P. guttatus, and no apparent relationship in B. imperator.<h4>Conclusions</h4>The study indicates interspecific variation in corticosterone deposition in snake shed skin and demonstrates that the relationship between housing conditions and corticosterone levels is species-specific. More active species, such as P. guttatus, may be more sensitive to spatial restriction and limited environmental complexity, whereas less active species, such as P. regius and B. imperator, may respond differently to housing conditions. These findings underscore the importance of species-tailored welfare guidelines, suggesting that enclosure design and enrichment strategies should be adapted to the behavioural ecology and physiological characteristics of individual snake species rather than applied uniformly across taxa.\n  Source: https://pubmed.ncbi.nlm.nih.gov/42032687/\n\nSource text: `pdf-raw/evidence/europepmc_ball_python_husbandry_health_2026-08-01.txt` (Europe PMC first-hand abstracts, pulled 2026-08-01).\n","sources":["Europe PMC — Evidence cluster — Ball python (Python regius) husbandry, health & nutrition (peer-reviewed, Europe PMC) (retrieved 2026-08-01)"],"source":{"authority":"Europe PMC","title":"Evidence cluster — Ball python (Python regius) husbandry, health & nutrition (peer-reviewed, Europe PMC)","url":"https://pubmed.ncbi.nlm.nih.gov/42193776/","retrieved":"2026-08-01","ref":"PMID 42193776","doc_type":"official PDF","source_document":"Peer-reviewed snake husbandry/health/nutrition literature (Europe PMC, first-hand abstracts)","verification_file":"pdf-raw/evidence/europepmc_ball_python_husbandry_health_2026-08-01.txt"},"source_document":"Peer-reviewed snake husbandry/health/nutrition literature (Europe PMC, first-hand abstracts)","source_file":"pdf-raw/evidence/europepmc_ball_python_husbandry_health_2026-08-01.txt","tokens_estimated":600,"generated_at":null,"tip":"Use /api/v1/topics to discover more topics. /api/v1/nutrient for precise single-point queries. /api/v1/cross_compare for 2-3 standard comparisons."}
