Abstract (opening): <i>Listeria</i> (<i>L.</i>) <i>ivanovii</i> is a Gram-positive, facultatively intracellular rod-shaped bacterium. It is predominantly associated with animal infections, particularly in ruminants. Unlike <i>L. monocytogenes</i>, which is widely recognised as a major zoonotic and foodborne pathogen, <i>L. ivanovii</i> is often overlooked, despite documented cases of abortion, stillbirth, and neonatal septicemia in sheep, goats, and cattle. This review provides an overview of <i>L. ivanovii</i> taxonomy, microbiological characteristics, virulence determinants, host adaptation, epidemiology, transmission routes, diagnostic challenges, antimicrobial susceptibility, and preventive measures in animal husbandr<i>y</i>. Available evidence suggests that infections with <i>L. ivanovii</i> tend to be sporadic, with occasional outbreaks of abortions in small ruminant flocks. Large-scale epizootics and sustained interregional spread have not been documented. Human infections are rare and predominantly occur in immunocompromised individuals, which supports the assumption that the zoonotic potential is limited under normal conditions. Underdiagnosing and missing awareness likely contribute to the perception of rarity, as routine laboratory workflows often do not differentiate <i>Listeria</i> species beyond the genus level. The increasing use of molecular confirmation and whole-genome sequencing may improve species-level detection and clarify epidemiological patterns. Overall, <i>L. ivanovii</i> should be regarded as a specialised pathogen predominantly associated with ruminants and of veterinary relevance. Improved diagnostics and integration into existing surveillance frameworks could enhance our understanding of its true epidemiological role and prevent it from being endemic.\n  Source: https://pubmed.ncbi.nlm.nih.gov/42290788/\n- **PMID 41924379 (2026, International journal of ophthalmology)** — Differentially expressed genes in rabbits with traumatic proliferative vitreoretinopathy based on high-throughput sequencing.. Abstract (opening): <h4>Aim</h4>To identify differentially expressed genes (DEGs) in rabbits with traumatic proliferative vitreoretinopathy (PVR) using high-throughput sequencing (HTS).<h4>Methods</h4>Thirty-six rabbits were randomly allocated to the control group and the PVR group induced by scleral puncture. On the 28<sup>th</sup> day following modeling, fundus B-ultrasound and fundus photography were performed on all rabbits, and hematoxylin-eosin (HE) staining was conducted on retinal tissues. RNA sequencing (RNA-Seq) combined with bioinformatics analysis was used to screen PVR-associated DEGs. Gene Ontology (GO) functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were carried out for the identified DEGs. S100A6, EDNRB and CEBPD were randomly selected for quantitative reverse transcription polymerase chain reaction (RT-qPCR) validation to verify the reliability of the RNA-Seq results.<h4>Results</h4>Fundus B-ultrasound, fundus photography and retinal HE staining confirmed the successful establishment of the traumatic PVR rabbit model. A total of 1587 DEGs were screened, of which 1094 were significantly up-regulated and 493 were significantly down-regulated. GO function enrichment analysis showed that these DEGs were mainly enriched in immune response, extracellular region and inflammatory response. KEGG pathway enrichment analysis showed that DEGs were mainly involved in the cytokine-cytokine receptor interaction and hematopoietic cell lineage pathway. RT-qPCR results showed that S100A6, CEBPD and EDNRB were significantly increased in PVR group.<h4>Conclusion</h4>A large number of genes exhibit significant differential expression in rabbits with traumatic PVR, among which S100A6, CEBPD and EDNRB may play an important role in traumatic PVR.\n  Source: https://pubmed.ncbi.nlm.nih.gov/41924379/\n- **PMID 41893328 (2026, Metabolites)** — An Initial Assessment of Rabbit Cornea as a Biomarker of Trace-Element Load in Commercial Animal Production.. Abstract (opening): <b>Background/Objectives:</b> Assessing trace-element status is fundamental for maintaining health across species. However, serum primarily reflects acute physiological variability rather than chronic exposure. Thus, we investigate the cornea as a possible stable, practical alternative for assessing chronic copper and iron accumulation in rabbit's cornea. <b>Methods:</b> A group of laboratory rabbits was housed under standardized husbandry conditions with comparable environmental and dietary backgrounds for trace-element intake. After completion of the experimental phase, corneal tissues were collected and subjected to quantitative elemental analysis using validated spectrometric procedures. In parallel, the structural integrity of the cornea was evaluated with standard histological techniques to determine whether elevated trace-element levels were associated with detectable morphological alterations. <b>Results:</b> Copper and iron concentrations showed approximately normal distributions, with mean values of 0.93 ± 0.46 μg/g and 0.78 ± 0.32 μg/g. All elemental concentrations were calculated relative to the original (native) wet tissue weight. Several samples exhibited elevated levels of both elements. Importantly, even in the samples with the highest copper and iron concentrations, no histological abnormalities were observed. Epithelial layers were intact, stromal collagen was well organized, and no inflammation or edema was observed. <b>Conclusions:</b> Overall, the cornea contained measurable copper and iron levels, and higher concentrations were not associated with morphological disruption under the trace-element conditions studied. Because ocular tissues are not used in food processing and can be collected in a standardized way during slaughter, the cornea offers a practical matrix for post-mortem monitoring of trace-element load in commercial animal production.\n  Source: https://pubmed.ncbi.nlm.nih.gov/41893328/\n- **PMID 41831160 (2026, Tropical animal health and production)** — An assessment of Nigeria's microlivestock value chain: insights from six species.. Abstract (opening): Microlivestock farming offers potential to improve incomes and nutrition in Nigeria, yet the subsector remains fragmented and underdeveloped. There is, in addition, a lack of reliable data to support value-chain-wide development. This study presents an explorative, mixed-methods assessment of the value chains of six microlivestock species commonly raised in Nigeria. The study was conducted in six purposively selected states: Oyo (rabbits), Anambra (grasscutters), Ondo (snails), Katsina (guinea fowl), Plateau (quail), and Kwara (honeybees), spanning five agroecological zones, integrating data from questionnaire surveys (n = 114), gender-disaggregated focus group discussions (n = 120), and key informant interviews (n = 18). Microlivestock production was the primary source of livelihood for 10% (honeybees) to 33.3% (grasscutter) of farmers sampled. Across the value chains, the proportions of surveyed farmers engaged in multiple economic activities ranged from 10.0% (guinea fowl) to 88.9% (quail), indicating the supplementary role of microlivestock to household incomes. Farmer association membership was highest among rabbit (95%), honeybee (70%), and grasscutter (61.1%) farmers. In comparison, farmers of guinea fowl (10.0%), quail (17.0%), and snail (27.8%) in the sample had lower rates of association membership. The farmers reported persistent challenges, including limited access to specialized feed and veterinary services, and weak market linkages. The study participants also reported gender disparities and barriers to youth participation in microlivestock value chains, despite high youth interest. The study identified strategic opportunities in the formation of cooperatives, digital marketing, e-commerce, species-specific extension, and supporting youth-led enterprises. The findings underscore the need for gender-sensitive, youth-inclusive policies and programs, alongside species-targeted interventions in the subsector. This assessment provides evidence to support current livestock policies and strategies, as well as the integration of microlivestock into broader livestock reform agendas.\n  Source: https://pubmed.ncbi.nlm.nih.gov/41831160/\n- **PMID 42050646 (2026, Veterinary research)** — Cryptosporidium infections in animals across Asia (2015-2025): a systematic review and meta-analysis of prevalence, host range, geographic distribution, and molecular epidemiology.. Abstract (opening): Cryptosporidium spp. is a globally significant protozoan parasite with profound implications for animals, humans, and environmental health. Despite extensive research, its distribution, prevalence, and diversity across Asia remain fragmented. A systematic review and meta-analysis were conducted on studies published between 2015 and 2025, incorporating 329 investigations from 29 Asian countries and analyzing 142,484 animal specimens. Pooled prevalence was calculated, and molecular epidemiological data were synthesized to characterize species distribution and subtype diversity. The overall pooled prevalence of Cryptosporidium among animals across Asia was 12%, with the highest prevalence reported in West Asia (19.8%). Infections were most frequent in livestock (13.1%), followed by wildlife (9.1%), reflecting the parasite's expanding host range. Molecular analysis revealed the presence of > 74 species and 71 subtypes, with C. parvum (n = 93), C. andersoni (n = 55), C. bovis (n = 43), and C. ryanae (n = 40) being the most frequently reported. C. parvum demonstrated the broadest host spectrum, detected in > 37 animal species, with subtype family IId (n = 49) prevalent in > 22 hosts, underscoring its epidemiological importance. Over the past decade, the prevalence of Cryptosporidium and its host diversity has increased significantly across Asia, accompanied by marked genetic heterogeneity. These findings provide critical insights into transmission dynamics and regional hotspots. This synthesis highlights the urgent need for coordinated surveillance and a \"One Health Strategy\" to mitigate the risks posed by this adaptable and widespread pathogen.\n  Source: https://pubmed.ncbi.nlm.nih.gov/42050646/\n- **PMID 42276977 (2026, Health & social work)** — Mental Workload and Burnout among Social Work Professionals in Spain: The Protective Role of Psychological Capital and Perceived Social Support.. Abstract (opening): Social workers are at high risk of suffering from burnout syndrome due to the high work demands and the characteristics of their professional practice, yet there is little research that investigates the predictors and protectors of burnout among this group. This article examined the relationship between mental workload (MWL) and burnout in a sample of Spanish social workers. In addition, it analyzed whether psychological capital (PC) and perceived social support (PSS) mediate this relationship. For this purpose, 270 social work professionals completed an online questionnaire that collected information on MWL, PC, PSS, and burnout. The results show that MWL predicts burnout, and that PC and PSS only partially mediate the relationship between MWL and burnout. However, the direct effect of MWL on burnout remains significant, suggesting that other factors may also be involved. Nevertheless, PC and PSS act as internal and external protective factors, respectively, of burnout. This work underlines the importance of implementing interventions to strengthen personal resources and social support as a way to prevent burnout in social workers.\n  Source: https://pubmed.ncbi.nlm.nih.gov/42276977/\n- **PMID 42349044 (2026, Hearing research)** — Functional and histological assessment of 3D-printed helmet and hearing protection devices in preventing blast-induced auditory injury in Chinchillas.. Abstract (opening): Blast-induced auditory injury remains a persistent concern in many high-risk occupational environments, especially military service members and veterans. Although helmets and hearing protection devices (HPDs) have independently demonstrated efficacy in mitigating acoustic injuries, the synergistic protective effect of their combined use against blast overpressure (BOP) has not been comprehensively evaluated. The present study investigated the auditory protective performance of a custom-engineered 3D-printed helmet, both independently and in conjunction with HPDs, in a chinchilla model subjected to repeated high-intensity blast exposures. Finite element analysis (FEA) was harnessed to optimize the design and the material selections of the three-layered, stiffness gradient helmet, leading to 47% reduction of the peak stress in the chinchilla's skull. Four cases were tested during blast experiments including unprotected, earplugged, helmeted, and dual-protection. Animals were exposed to three consecutive blasts with a peak amplitude up to 25 psi (175 kPa, equivalent to 199 dB SPL) under anesthesia. Auditory function test of auditory brainstem responses (ABR), middle latency responses (MLR), and distortion product otoacoustic emissions (DPOAE) were performed. The dual-protection group demonstrated the smallest ABR threshold shifts with reductions of up to 40 dB compared with the unprotected group, along with the greatest preservation of ABR Wave I amplitudes and stable MLR amplitudes. The cochleae were harvested for histological analysis, involving immunostaining to assess hair cell survival and quantify hair cell loss across cochlear regions. DPOAE amplitudes showed pronounced recovery following blast exposures, corresponding with significant less losses of cochlear hair cells and improved preservation of both inner and outer hair cells.\n  Source: https://pubmed.ncbi.nlm.nih.gov/42349044/\n- **PMID 42405782 (2026, Microbiology spectrum)** — Establishment of a chinchilla model of &lt;i&gt;Achromobacter xylosoxidans&lt;/i&gt;-induced otitis media.. Abstract (opening): <i>Achromobacter xylosoxidans</i> (Ax) is an emerging opportunistic pathogen associated with chronic respiratory infections, particularly in individuals with cystic fibrosis; however, its role in otitis media (OM) and the mechanisms that underlie middle ear infection remain poorly defined. Despite its initial isolation from middle ear effusions decades ago, no experimental models of Ax-induced OM have been established. Here, we report the development of a reproducible chinchilla model of Ax-induced OM, which, to our knowledge, represents the first experimental model of Ax-induced middle ear infection. Following transbullar inoculation, two well-characterized clinical isolates established middle ear infection and induced measurable changes in tympanometry and otoscopic pathology. Notably, strain-specific differences in disease severity and persistence were observed, with one isolate inducing more pronounced inflammation, reduced tympanic membrane compliance, and prolonged bacterial survival within the middle ear mucosa. At the study endpoint, viable bacteria were recovered from a subset of infected ears despite resolution of overt clinical signs, which indicated a capacity for persistent mucosal infection. These findings demonstrate that Ax can establish and maintain infection within the middle ear and that clinical isolates exhibit distinct pathogenic phenotypes in this model. Together, this work establishes a reproducible and clinically relevant <i>in vivo</i> model for the study of Ax-induced OM and provides a foundation for future investigations into host-pathogen interactions, persistence mechanisms, and therapeutic interventions.<h4>Importance</h4><i>Achromobacter xylosoxidans</i> is an emerging opportunistic pathogen increasingly associated with chronic mucosal infection, yet its role in otitis media remains poorly defined. Mechanistic studies of middle ear infection have been limited by the absence of an experimental model. We establish the first reproducible animal model of <i>A. xylosoxidans</i>-induced otitis media and demonstrate that clinical isolates differ in their capacity to drive disease severity within the middle ear. By enabling controlled investigation of infection dynamics <i>in vivo</i>, this model provides a framework to define determinants of pathogenesis and directly compare strain-specific phenotypes across mucosal environments. These findings establish a foundation for future studies of <i>A. xylosoxidans</i> infection and therapeutic intervention.\n  Source: https://pubmed.ncbi.nlm.nih.gov/42405782/\n- **PMID 41986311 (2026, Cell death & disease)** — The RIPK3-IL-6 axis mediates kidney injury in cytokine storm syndrome.. Abstract (opening): Receptor-interacting protein kinase 3 (RIPK3) is best known as a mediator of necroptosis, a regulated necrosis pathway observed in diseases with high inflammatory components. We explored the role of RIPK3 in cytokine storm syndrome (CSS)-induced acute kidney injury induced by lipopolysaccharide (LPS) in wild-type and Ripk3-deficient mice. For the in vitro experiments, we treated both primary tubular epithelial cells and bone marrow-derived cells from wild-type and Ripk3-deficient mice with LPS. Ripk3 deficiency improved renal function and increased survival in CSS, a common condition observed in severe infections and other scenarios, and protection was associated with reduced inflammation. Mechanistically, the necroptosis pathway did not play a key role in kidney protection by Ripk3 deficiency, and the NLRP3 inflammasome was partially implicated. Olink plasma proteomics identified IL-6 as the most upregulated inflammatory protein in the kidney and circulation, and it was most responsive to Ripk3 deficiency. Ripk3-deficient mice had suppressed kidney, liver, and lung Il-6 expression as well as suppressed kidney activation of STAT3, a transcription factor downstream of IL-6. In bone marrow chimeric mice, RIPK3-expressing bone marrow-derived cells were required to drive IL-6 expression, and AKI and kidney Il-6 expression correlated with loss of renal function. In this regard, in vitro experiments have shown that RIPK3 mediates Il-6 expression in bone marrow cells but not in tubular cells. Additionally, targeting the IL-6 receptor improves kidney function and reduces kidney inflammation in CSS-AKI. Kidney transcriptomic data of human AKI associated with COVID-19 CSS were consistent with activation of the RIPK3-IL-6 axis. The RIPK3-IL-6 axis in bone marrow cells mediates systemic inflammation and kidney injury induced by a cytokine storm, independent of the necroptosis and inflammasome pathways. Specific targeting of bone marrow RIPK3 may limit kidney inflammation, without the potential adverse effects of systemic RIPK3 targeting.\n  Source: https://pubmed.ncbi.nlm.nih.gov/41986311/\n- **PMID 42354167 (2026, Foods (Basel, Switzerland))** — The Risk of Acrylamide Intake from Roasted Arabica Coffee (Pure, Torrefacto and Soluble) Consumed in Costa Rica.. Abstract (opening): Acrylamide (AA) is a contaminant with carcinogenic and genotoxic properties that occur in heat-produced food products. This study aimed to evaluate the occurrence of AA in different coffee products commercially sold in retail markets of Costa Rica and to develop a probabilistic exposure assessment model to assess the potential human health risk due to its consumption. The average AA concentration in the coffee samples analyzed (<i>n</i> = 110) was 110.29 ± 151.61 µg kg<sup>-1</sup>. The mean dietary exposure (DE) values, for the middle-bound (MB) approach, varied from 0.025 to 0.083 µg kg<sup>-1</sup> BW per day. The margin of exposure (MOE) was calculated with a BDML<sub>10</sub>: 430 μg kg<sup>-1</sup> BW day<sup>-1</sup> for neurotoxicity and 170 μg kg<sup>-1</sup> BW day<sup>-1</sup> for cancer effect, according to EFSA (2015). No neurotoxicity risk was identified as MOE values ranged from 4291 to 467,984 for the adult male population, from 4566 to 477,203 for the adult females, from 4265 to 506,062 for the male minors and from 2512 to 495,151 for the female minors. On the other hand, MOE values for the carcinogenic risk were below 10,000 for the mean and P95th coffee consumers, denoting a possible health concern. The values ranged from 1696 to 6717 for the adult male population, from 1805 to 7201 for the female adults, from 1686 to 6304 for the male minors and from 993 to 2155 for the female minors. The mean incremental lifetime cancer risk (ILCR) values for male adult, female adult, male minor, and female minor were 1.7 × 10<sup>-5</sup>, 1.6 × 10<sup>-5</sup>, 1.9 × 10<sup>-5</sup>, and 3.9 × 10<sup>-5</sup>, respectively, for the MB approach. These results denote a potential or considerable risk in consumption of coffee due to AA intake. Thus, no neurotoxicity risk was identified; however, a potential carcinogenic risk was observed based on MOE and ILCR results.\n  Source: https://pubmed.ncbi.nlm.nih.gov/42354167/\n- **PMID 42442253 (2026, Hearing research)** — Comparing physiological signatures of synaptopathic noise exposure and carboplatin-induced inner-hair-cell dysfunction in chinchillas.. Abstract (opening): Aging and noise over-exposure lead to complex mixtures of cochlear degradation that impair the structure and function of outer hair cells (OHCs), inner hair cells (IHCs), and the cochlear nerve. However, IHC damage and cochlear synaptopathy (CS) remain pathologies \"hidden\" from the audiogram. This study aimed to compare and contrast the physiological signatures of these two popular and distinct exposure paradigms using promising non-invasive assays: Envelope Following Responses (EFRs), Auditory Brainstem Response (ABRs), Wideband Middle-Ear Muscle Reflexes (WB-MEMRs), and Distortion Product Otoacoustic Emissions (DPOAEs). We utilized chinchilla models of carboplatin exposure (CA) (N = 4) and temporary threshold shift (TTS) noise-induced CS (N = 4) to compare the physiological signatures of each type of exposure. While both groups showed unchanged ABR thresholds two weeks after exposure, EFRs, ABR Wave 5/1 ratios, and MEMRs showed distinct effects of exposure. CA and TTS exposures showed differences in the pattern and degree of decreased EFR \"peakiness\" across different stimulus modulation types (e.g., sinusoidal vs. rectangular). Significant elevations in ABR Wave 5/1 ratios were less-pronounced in the TTS-exposed animals. Reduced WB-MEMR amplitudes and increased WB-MEMR thresholds occurred in both groups, although this effect was more pronounced for TTS. Opposite trends in DPOAE amplitudes suggest that effects on OHC integrity and auditory efferent physiology may differ between the two exposure types and their induced pathologies. Overall, these results suggest a combination of EFR \"peakiness\", ABR Wave 5/1 ratio, and WB-MEMR may be useful for profiling IHC dysfunction and CS as potentially distinct forms of hidden hearing loss.\n  Source: https://pubmed.ncbi.nlm.nih.gov/42442253/\n- **PMID 42240518 (2026, Medical mycology)** — Genotype structure of Trichophyton mentagrophytes complex from companion animals in France reveals restricted diversity.. Abstract (opening): The Trichophyton mentagrophytes complex includes pathogens of major relevance in both human and veterinary medicine. Despite growing knowledge of the rDNA Internal Transcribed Spacer (ITS) region diversity within the complex, data on circulating genotypes in animals remain scarce. We analyzed 348 T. mentagrophytes isolates obtained from companion animals in France in 2020 to describe ITS genotype distribution and assess the presence of T. indotineae and T. mentagrophytes ITS-genotype VII. Eight ITS genotypes were identified, with genotype III* largely predominant (62.4%), followed by genotypes III (22.4%) and II* (8.6%). No significant difference in genotype distribution was observed between cats and dogs. Genotype XXIV was exclusively detected in the three chinchilla isolates, while genotype XXVI-Uhrlass was identified in 17 cases. Three previously undescribed ITS genotypes were also recorded. Sequencing of tef1-α and tubb in a subset of isolates showed limited diversity within each ITS genotype, except for genotype III*, which exhibited several sequence variants. Mating-type analysis revealed both idiomorphs in the collection, although a single idiomorph was detected within each ITS genotype except genotype III*. Genotypes III and XXVI exhibited a restricted geographical distribution. Neither T. indotineae, T. mentagrophytes ITS-genotype VII, nor T. interdigitale ITS genotypes were identified. Our results highlight restricted genetic diversity among companion animal-derived isolates in France and support reduced genetic mixing among ITS genotypes, consistent with ongoing speciation processes within T. mentagrophytes species complex.\n  Source: https://pubmed.ncbi.nlm.nih.gov/42240518/\n\nSource text: `pdf-raw/evidence/europepmc_chinchilla_husbandry_health_2026-08-01.txt` (Europe PMC first-hand abstracts, pulled 2026-08-01).\n","sources":["Europe PMC — Evidence cluster — Chinchilla (Chinchilla lanigera) husbandry, health & nutrition (peer-reviewed, Europe PMC) (retrieved 2026-08-01)"],"source":{"authority":"Europe PMC","title":"Evidence cluster — Chinchilla (Chinchilla lanigera) husbandry, health & nutrition (peer-reviewed, Europe PMC)","url":"https://pubmed.ncbi.nlm.nih.gov/42290788/","retrieved":"2026-08-01","ref":"PMID 42290788","doc_type":"official PDF","source_document":"Peer-reviewed Chinchilla husbandry/health/nutrition literature (Europe PMC, first-hand abstracts)","verification_file":"pdf-raw/evidence/europepmc_chinchilla_husbandry_health_2026-08-01.txt"},"source_document":"Peer-reviewed Chinchilla husbandry/health/nutrition literature (Europe PMC, first-hand abstracts)","source_file":"pdf-raw/evidence/europepmc_chinchilla_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."}
