Abstract (opening): Social housing of animals is well recognized as a fundamental element in providing for the well-being of social animals during laboratory research activities but is contraindicated in some experimental designs. To ascertain if social housing represented a potential confounder in studies determining influenza A virus (IAV) pathogenicity conducted in the ferret model, we analyzed data from ferrets inoculated with 56 distinct IAV strains, where animals were housed either singly or in pairs postinoculation. Parameters examined included frequency of lethal outcomes, timing and magnitude of clinical signs (weight loss and fever), and magnitude and kinetics of viral shedding in the upper respiratory tract. Statistical differences between IAV-inoculated ferrets housed in either setting were not consistently detected among any parameters examined, supporting that data from ferrets inoculated with a diverse range of avian- and mammalian-origin IAV housed singly or in social pairs may be combined and analyzed without confounding based on this variable. This study supports the utility of performing retrospective analyses to ensure results obtained from in vivo experimentation are interpreted to the highest standard possible. Further, it aligns with ethical obligations of researchers who perform in vivo experimentation to ensure these studies are designed to meet both animal welfare considerations and research goals.\n  Source: https://pubmed.ncbi.nlm.nih.gov/41698665/\n- **PMID 41902252 (2026, Viruses)** — Animal Models for Swine Influenza Virus Research: Pathology, Viral Dynamics, and Immune Responses.. Abstract (opening): Swine influenza virus (SIV) continues to evolve and possesses notable zoonotic potential, making it an important respiratory pathogen of concern for both the global swine industry and public health. Owing to antigenic drift, genetic reassortment, and regional lineage diversity, vaccine efficacy against SIV shows marked variability across different epidemiological contexts. Therefore, establishing appropriate animal models to dissect its pathogenic mechanisms, transmission characteristics, and immune response patterns is of critical importance. This review systematically summarises the animal models commonly used in SIV research, including mice, ferrets, guinea pigs, pigs, and non-human primates, and provides an integrated analysis across three core dimensions: pathological manifestations, viral replication kinetics, and immune architecture. The evidence indicates that substantial inter-model differences exist in pulmonary lesion distribution, transmission efficiency, mucosal immune development, and cellular immune complexity, which in turn define their functional roles in mechanistic studies, transmission research, and vaccine evaluation. Building on this framework, this review further emphasises the value of a tiered, multi-model strategy in SIV research. In vitro systems and mouse models are well suited for early mechanistic exploration and preliminary vaccine screening; ferret and guinea pig models facilitate the evaluation of transmission dynamics; and the pig model, as the natural host system, remains the critical platform for confirming protective efficacy, identifying potential immunopathological risks, and assessing translational relevance. Importantly, the potential occurrence of vaccine-associated enhanced respiratory disease under antigen-mismatched conditions highlights the need to evaluate both protective performance and immunological safety during vaccine development. Overall, rational integration of evidence across multiple models, anchored to the natural host, will improve the predictability and translational reliability of SIV vaccine research.\n  Source: https://pubmed.ncbi.nlm.nih.gov/41902252/\n- **PMID 41987827 (2026, ISME communications)** — How \"pro\" are probiotics for wildlife species? Novel data, lack of evidence, and future directions.. Abstract (opening): Treatments that aim to purposefully manipulate host-associated microbiomes are now prevalent in human and animal medicine. Probiotics that contain live bacteria are purported to improve microbiome function and host health. Although research is advancing, commercial probiotic development has outpaced empirical study of probiotic efficacy. Probiotics are widely used in <i>ex-situ</i> wildlife care despite a lack of empirical study or support. We interrogate the relevance of commercial probiotics in <i>ex-situ</i> wildlife by (a) sequencing the composition of commercial probiotics used to treat wildlife, (b) comparing the probiotic sequences to data on the microbiomes of >900 animal species, and (c) characterizing the effects of a commercial probiotic on probiotic colonization, prevalence of a potential enteric pathogen (<i>Clostridium perfringens</i>), and metagenomic function in endangered black-footed ferrets (<i>Mustela nigripes</i>). We found mislabeling and potential contaminants in probiotics marketed for a range of species. The probiotic bacteria were rare or absent in published animal microbiomes. In black-footed ferrets, probiotic treatment induced minimal probiotic colonization, negligible functional change, and limited influence on the potential enteric pathogen. Given our findings, which reiterate concerns about the efficacy of commercial probiotics across human and animal sectors, greater effort must be put towards identifying species-specific probiotic candidates and studying alternative microbial therapies for wildlife under human care.\n  Source: https://pubmed.ncbi.nlm.nih.gov/41987827/\n- **PMID 41569108 (2026, Journal of virology)** — Immune history confers antibody- and T cell-dependent cross-protection against highly pathogenic avian influenza H5N1 viruses.. Abstract (opening): The outbreak of highly pathogenic avian H5 influenza (HPAI) clade 2.3.4.4b in cattle has spread across the United States. Mice with pre-existing immunity to H1N1 virus or with a live-attenuated influenza vaccine showed protection against a lethal bovine-derived HPAI H5N1 viral challenge. Notably, ferrets with mixed immunity also demonstrated protection against a feline-derived H5N1 virus, independent of cross-reactive neutralization titers, but antibodies to whole virus were observed. To investigate protective factors, we conducted T cell epitope mapping using published H1N1 viral sequences and found high conservation of key T cell epitopes in the bovine HPAI H5N1 strain. Depletion of T cells in mice prior to and during primary H1N1 infection impacted cross-protective antibodies to H5N1 virus, with CD4 depletion increasing mortality and CD8 depletion mildly impacting morbidity upon H5N1 viral challenge. This underscores the need to investigate memory T cell responses alongside antibodies in assessing preexisting cross-protection to HPAI H5N1 viruses.IMPORTANCEThe rapid spread of highly pathogenic avian H5 influenza (HPAI) clade 2.3.4.4b in U.S. cattle represents an urgent and evolving public health threat. Our findings reveal that pre-existing immunity, whether from seasonal H1N1 infection or live-attenuated vaccination, can confer substantial protection against lethal bovine- and feline-derived HPAI H5N1 viruses, even in the absence of strong cross-neutralizing antibody titers. By integrating T cell epitope mapping with mechanistic depletion studies, we demonstrate that conserved CD4 and CD8 T cell epitopes across H1N1 and H5N1 strains underpin this cross-protection. Critically, loss of CD4 T cell help during primary H1N1 infection disrupts the development of cross-reactive antibody responses and markedly worsens outcomes after H5N1 challenge. These results identify memory T cell responses as important determinants of heterosubtypic immunity and highlight the need to incorporate T cell-focused metrics into risk assessment, vaccine evaluation, and preparedness strategies for emerging HPAI H5N1 viruses.\n  Source: https://pubmed.ncbi.nlm.nih.gov/41569108/\n- **PMID 42200669 (2026, Journal of virology)** — Going wild: prioritizing experimental models of rodent-borne viruses to decode zoonotic spillover and pandemic risk.. Abstract (opening): Rodent-borne viruses pose threats to global health because of their capacity for zoonoses with the potential to cause outbreaks of high morbidity and mortality. Gaining a deeper understanding of how these viruses persist in their reservoir hosts and spillover into human populations requires an integrated approach blending both laboratory- and field-based research. Here, we review our current understanding of rodent-borne virus dynamics-primarily mammarenaviruses and orthohantaviruses-within their natural rodent reservoirs. We highlight key insights gained from experimental infection models seeking to replicate authentic host-pathogen interactions under controlled conditions. We argue that expanding and refining experimental models, particularly those that simulate natural reservoir conditions, is crucial to identifying the host and viral factors facilitating viral persistence in nature, and transmission to human populations. We propose a framework for future research that prioritizes hypothesis-driven research in model systems that are both natural and translatable to bridge these knowledge gaps.\n  Source: https://pubmed.ncbi.nlm.nih.gov/42200669/\n- **PMID 41577806 (2026, Scientific reports)** — Development of a paediatric model of diffuse traumatic brain injury in ferrets.. Abstract (opening): Traumatic brain injury (TBI) is a leading cause of death and disability in children, especially those under five, with younger children more vulnerable to persistent cognitive and neuropsychological effects due to disrupted brain development. Paediatric brains are biomechanically more susceptible to diffuse axonal injury due to anatomical differences, with axonal injury observed in up to 80% of hospitalized children. Despite this, many preclinical TBI models focus on focal injuries, whereas to better model the evolution of axonal injury in the paediatric brain, clinically-relevant diffuse pre-clinical models are required. In this study gyrencephalic paediatric ferrets (2–3 months) equivalent to a 3–5-year-old child were injured with the Closed Head Impact Model of Engineered Rotational Acceleration (CHIMERA), and the axonal injury response and resultant motor and cognitive deficits examined to 72 h post-injury. Injury was associated with extensive axonal injury, as detected via both the amyloid precursor protein (APP) for transport disruption and neurofilament light (NFL) for neurofilament integrity, in key structures including the corpus callosum, fornix and cortical white matter. Serum GFAP was increased within 30 min of injury, returning to baseline by 72 h, with NFL elevated from 24 h to 72 h post-injury. Injured ferrets had deficits in balance, working memory and spatial memory. The adaptation of the CHIMERA model to paediatric ferrets provides the opportunity to investigate factors driving axonal pathology post-injury and how these interact with neurodevelopment.\n  Source: https://pubmed.ncbi.nlm.nih.gov/41577806/\n- **PMID 41969628 (2026, Acta biochimica Polonica)** — Species barriers in AAV tropism: mechanisms, models, and emerging solutions for clinical translation.. Abstract (opening): Adeno-associated virus (AAV) vectors have become central to <i>in vivo</i> gene therapy across genetic and acquired diseases. Yet despite extensive preclinical validation, AAV programs often encounter translational gaps when advancing from rodents to non-human primates (NHPs) and ultimately to humans. These species barriers arise from differences in capsid-receptor interactions, intracellular trafficking, immune landscapes, and tissue microanatomy. Even within species, strain-level genetic variation can markedly alter vector performance, exemplified by the LY6A-dependent central nervous system (CNS) tropism of AAV-PhP.B in C57BL/6J mice. Old world monkeys, which are evolutionarily closer to humans than new world species, remain the most widely used models for systemic and CNS delivery, yet discrepancies in seroprevalence, complement activity, endothelial biology, and neuronal susceptibility still limit predictability. Recent advances, including machine learning-guided capsid design, deep mutational scanning, and human-derived organoids and explant models, offer powerful tools to bridge these barriers. This mini-review synthesizes current understanding of AAV species barriers and outlines strategies that enhance the robustness and human relevance of AAV gene therapy development.\n  Source: https://pubmed.ncbi.nlm.nih.gov/41969628/\n- **PMID 42498819 (2026, Nature microbiology)** — Antiviral GHP-88310 blocks contact-mediated and airborne transmission in a ferret model of measles-like disease.. Abstract (opening): The 2025/2026 measles resurgence in North America highlighted that antivirals may be valuable in protecting child health because of mounting vaccination hesitancy. The drug candidate GHP-88310 is an orally efficacious broad-spectrum orthoparamyxovirus polymerase inhibitor, but its effect on viral transmission is unclear. Here we used canine distemper virus, which causes measles-like disease in ferrets, and established direct-contact and airborne canine distemper virus transmission models to examine pharmacological suppression of virus spread. Prophylactic GHP-88310 administration alleviated clinical signs of direct contacts and all sentinels survived. Pre- and post-exposure prophylactic GHP-88310 given twice daily to air contacts prevented transmission. Once-daily prophylactic administration mediated complete survival with all air contacts undergoing seroconversion. Therapeutic treatment of air contacts mitigated clinical signs, and animals survived, whereas all vehicle-treated air contacts succumbed. Therapeutic treatment of infected source animals shortened the contagious phase by 5 days. These results establish conceptual proof that GHP-88310 can suppress social contact transmission. Therapeutic treatment of sources promises epidemiological gain in addition to therapeutic benefit.\n  Source: https://pubmed.ncbi.nlm.nih.gov/42498819/\n- **PMID 42144799 (2026, Journal of viral hepatitis)** — Impact of Fatigue on Patient-Reported Outcomes and Work Productivity in Chronic Hepatitis B and C: Insights From a Multinational Registry Study.. Abstract (opening): Fatigue in chronic viral hepatitis may be associated with decreased health-related quality of life and other patient-reported outcomes (PROs). We evaluated the relationship between fatigue and PROs in patients with chronic hepatitis B (CHB) and chronic hepatitis C (CHC). Patients with CHB and CHC enrolled in the Global Liver Registry completed PRO instruments: FACIT-F, CLDQ (for CHB), CLDQ-HCV (for CHC), and WPAI:SHP. Fatigue was defined as FACIT-F Fatigue Scale (FS) score < 30 (scale range: 0-52). Among 2888 patients from 14 countries, 1561 had CHB (mean age 47 ± 13 years; 60% male; 13% advanced fibrosis; 13% depression; 17% fatigue) and 1327 had CHC (50 ± 13 years; 47% male; 21% advanced fibrosis; 18% depression; 28% fatigue). CHB-fatigue was associated with younger age, female, obesity, anxiety, depression (all p < 0.01) and worse PRO scores: CLDQ (scale 1-7): 4.1 ± 0.9 vs. 5.8 ± 0.9; FACIT score (range 0-108): 67.6 ± 14.5 vs. 87.7 ± 13.7; work productivity impairment (range 0-1): 0.33 ± 0.29 vs. 0.11 ± 0.22 (all p < 0.0001). Multivariable analysis confirmed the association of fatigue with lower PRO scores, impairment up to -23% (p < 0.01). CHC-fatigue was associated with female sex, obesity, type 2 diabetes, anxiety, depression (all p < 0.05) and worse PRO scores: CLDQ-HCV: 3.8 ± 1.0 vs. 5.5 ± 1.0; FACIT: 61.8 ± 14.1 vs. 85.6 ± 14.5; work productivity impairment: 0.49 ± 0.32 vs. 0.17 ± 0.25 (all p < 0.0001). In multivariable models, fatigue remained associated with reduced PRO scores, impairment up to -33% (p < 0.01). Almost one in five patients with chronic viral hepatitis report significant fatigue, which is associated with substantial PRO and work productivity impairment. Routine assessment for and management of fatigue in CHC or CHB care is essential.\n  Source: https://pubmed.ncbi.nlm.nih.gov/42144799/\n- **PMID 42381922 (2026, Bioinformatics advances)** — Interpretable machine learning for low-sample multi-omics: a case study of ferret vaccine response.. Abstract (opening): <h4>Motivation</h4>Machine Learning approaches continue to be critical to the modelling of complex biological pathways, but many of the most-used models suffer from being uninterpretable, providing little insight into underlying mechanisms. Interpretable machine learning (IML) offers a pathway to bridge predictive modeling and biological understanding.<h4>Results</h4>Here, we apply an IML framework combining TreeFARMS and Rashomon Set analysis to multi-omics data from a controlled ferret vaccination study as a case study. The dataset comprised transcriptomic, proteomic, lipidomic, and metabolomic profiles collected across ten time points from animals receiving different Inovio vaccine formulations. Using TreeFARMS, we generated sparse, interpretable decision trees optimized for accuracy and compactness, and explored their Rashomon Sets to identify stable and alternative molecular rules predictive of vaccination status. The resulting models outperformed the ensemble methods while producing concise if-then rules that directly linked measurable molecular features, such as AZGP1 expression and ketoleucine levels, to immune response patterns. This proof-of-concept study demonstrates that interpretable ML can capture biologically meaningful signatures of vaccine response without sacrificing predictive accuracy, providing a transparent and reproducible alternative to black-box approaches in multi-omics analysis.<h4>Availability and implementation</h4>The datasets generated and/or analysed during the current study are available at: https://github.com/nehlehk/iml-ferret-vaccine/tree/main/data .\n  Source: https://pubmed.ncbi.nlm.nih.gov/42381922/\n- **PMID 42236908 (2026, Cell death and differentiation)** — Cell death-induced release of the pro-aging protein acyl CoA binding protein (ACBP) into the circulation.. Abstract (opening): Acyl-CoA-binding protein (ACBP, encoded by diazepam binding inhibitor, DBI) is an abundant intracellular regulator of lipid metabolism that also circulates systemically, yet the mechanisms governing its release and its relationship to organ injury remain unresolved. Herein, we combine human multi-omics, mechanistic mouse models and controlled cell death assays to identify cell death-driven liberation of intracellular ACBP/DBI as a unifying mechanism underlying its elevation in disease. In a cohort of 1198 hospitalized adults, among whom 75% were acutely infected by SARS-CoV-2, plasma ACBP/DBI tightly correlated with inflammatory markers and biochemical signatures of cardiac, hepatic, renal, metabolic and hematologic dysfunction. SomaScan proteomics further revealed that ACBP/DBI co-varies with organ-enriched proteins, particularly those originating from skeletal muscle and pancreas, implicating tissue injury as a major determinant of its circulating abundance. Multiple forms of acute organ damage in mice, including hepatic or renal ischemia-reperfusion, bile duct ligation, pancreatitis and rhabdomyolysis, triggered rapid and robust increases in plasma ACBP/DBI. Using defined in vitro paradigms, we demonstrate that apoptosis, ferroptosis and necroptosis each cause loss of intracellular ACBP/DBI and its release upon plasma membrane permeabilization, independent of the upstream lethal pathway. These mechanistic insights translated in vivo: hepatocyte apoptosis, ferroptosis and necroptosis each elevated circulating ACBP/DBI in a manner attenuated by pathway-specific inhibitors. Finally, meta-analysis of >100,000 individuals across diverse populations revealed that elevated plasma ACBP/DBI consistently associates with systemic and organ-specific disease and predicts future morbidity. Together, our findings identify cell death-driven ACBP/DBI release as a conserved mechanism linking organ injury to increased plasma ACBP/DBI, positioning this molecule as an integrative biomarker of tissue damage across species, organs, and cell death modalities.\n  Source: https://pubmed.ncbi.nlm.nih.gov/42236908/\n- **PMID 42203822 (2026, Scientific reports)** — Intranasal infection of Rift Valley fever virus in the ferret model suggests multiple routes of neuroinvasion with consequential encephalitis and ophthalmitis.. Abstract (opening): Rift Valley fever virus (RVFV) causes haemorrhagic fever, ophthalmitis, and in severe cases, encephalitis in humans. Despite the well-recognised neurotropism, the mechanisms of central nervous system (CNS) invasion remain poorly understood. We investigated RVFV ingress into the CNS and resulting neuropathogenesis following intranasal inoculation in ferrets (Mustela putorius furo) (n = 15). At 3 DPI, before RVFV dissemination to the CNS, mild multifocal suppurative rhinitis and multifocal interstitial pneumonia were detected in the nasal cavity and lungs respectively, supported by detection of viral antigen and genome. From 6 DPI, infected ferrets exhibited neurological signs; by 6 - 8 DPI, a mild-to-moderate non-suppurative meningoencephalitis and myelitis was observed, progressing rostrally to caudally, with ophthalmitis observed from 7 DPI and 100% mortality by 8 DPI. Mild-to-moderate hyperaemia of the meninges was identified macroscopically in all infected ferrets. An immune response to infection was unable to prevent neuropathogenesis and clinical disease. Although our results suggest that neuroinvasion occurs via the olfactory route through the nasal turbinates to cranial nerves, virus replication in the lungs and presence of viremia implies that haematogenous dissemination into the CNS as a secondary route is possible. This relevant experimental ferret model may further contribute to understanding the pathogenesis of human RVFV infection.\n  Source: https://pubmed.ncbi.nlm.nih.gov/42203822/\n\nSource text: `pdf-raw/evidence/europepmc_ferret_husbandry_health_2026-08-01.txt` (Europe PMC first-hand abstracts, pulled 2026-08-01).\n","sources":["Europe PMC — Evidence cluster — Ferret (Mustela putorius furo) husbandry, health & nutrition (peer-reviewed, Europe PMC) (retrieved 2026-08-01)"],"source":{"authority":"Europe PMC","title":"Evidence cluster — Ferret (Mustela putorius furo) husbandry, health & nutrition (peer-reviewed, Europe PMC)","url":"https://pubmed.ncbi.nlm.nih.gov/41698665/","retrieved":"2026-08-01","ref":"PMID 41698665","doc_type":"official PDF","source_document":"Peer-reviewed Ferret husbandry/health/nutrition literature (Europe PMC, first-hand abstracts)","verification_file":"pdf-raw/evidence/europepmc_ferret_husbandry_health_2026-08-01.txt"},"source_document":"Peer-reviewed Ferret husbandry/health/nutrition literature (Europe PMC, first-hand abstracts)","source_file":"pdf-raw/evidence/europepmc_ferret_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."}
