- PMID 40726532 (2025, Veterinary research forum : an international quarterly journal) — First case of serpentovirus infection in a ball python (<i>Python regius</i>) in Thailand: a case report with molecular characterization.. Abstract (opening): The pet snake industry in Thailand has seen a significant rise in popularity, with the ball python (<i>Python regius</i>) becoming a frequently kept species. However, respiratory disease poses a notable health concern, and various viral pathogens, including serpentoviruses (formerly classified as nidoviruses), have been implicated. While serpentovirus infections have been reported globally in diverse snake species, no documented cases had previously been identified in Thailand. This case report describes a 9-month-old ball python presenting to the Reptile Science Clinic at the Queen Saovabha Memorial Institute in Bangkok, Thailand, with respiratory distress and emaciation. Despite veterinary intervention, the snake succumbed to the infection within two weeks. Post-mortem examination revealed marked mucus accumulation within the oral cavity and necrotic oral mucosa. Histopathological analysis demonstrated severe catarrhal pneumonia. Molecular investigations confirmed the presence of serpentovirus in the lung tissue of the affected python, with subsequent sequence analysis revealing close homology to known serpentoviruses in ball pythons. This report documents the first confirmed case of serpentovirus infection in a pet snake in Thailand. *[CC BY — Open Access, verbatim with attribution.]*

- PMID 41031330 (2025, Medical mycology case reports) — <i>Nannizziopsis arthrosporioides</i> infection mimicking ophidiomycosis in ball pythons (<i>Python regius</i>).. Abstract (opening): A wild caught snake presented with progressive dermatopathy and was euthanized due to a clinical suspicion for ophiomycosis. Over the next 7 days, six additional ball pythons, maintained in the same room but in separate cages from the index case developed similar progressive dermatomycoses and were euthanized. Histopathologic evaluation showed dermal granulomas with intralesional fungi and DNA from the lesions clustered in a monophyletic group with other isolates of <i>N. athrosporioides</i>. Colony and microscopic morphology of fungus from these cases matched published descriptions of <i>N. arthrosporioides</i>. While ophidiomycosis may be a major differential for dermatomycosis in snakes, molecular confirmation should be pursued, as additional fungi may cause similar lesions in this taxon. *[CC BY — Open Access, verbatim with attribution.]*

- PMID 40558139 (2025, Antibiotics (Basel, Switzerland)) — Antibacterial Activity of Some Essential Oils/Herbal Extracts Against Bacteria Isolated from Ball Pythons (<i>Python regius</i>) with Respiratory Infections.. Abstract (opening): <h4>Background</h4>Respiratory diseases are among the main causes of morbidity and mortality in captive reptiles. In Romania, pneumonia is a frequently observed illness affecting pet reptiles. Key factors contributing to the high incidence of pneumonia include inadequate animal husbandry, poor nutrition, and insufficient hygiene practices. Bacteria may act as primary pathogens or as facilitators of disease severity.<h4>Methods</h4>This study investigates bacterial strains from multiple genera and species (<i>Chryseobacterium</i> (<i>C.</i>) <i>indologenes</i>, <i>Staphylococcus</i> (<i>S.</i>) <i>epidermidis</i>, <i>Escherichia</i> (<i>E.</i>) <i>coli</i>, and <i>Pseudomonas</i> (<i>P.</i>) <i>aeruginoasa</i>) from six ball pythons regarding their antibiotic susceptibility and the effect of essential oils. Bacteria were isolated from the lower respiratory tract, displaying clinical signs of pneumonia. All isolates were tested with essential oils (lemongrass, oregano, rosemary, and sage) and a grapefruit seed extract (GSE) at different dilutions.<h4>Results</h4>The incidence of <i>Chryseobacterium indologenes</i> was highest (3 isolates/12 samples, 25%), followed by <i>E. coli</i> and <i>Staphylococcus epidermidis</i> (2/12 each, 16.6%), and <i>Pseudomonas aeruginoasa</i> (1/12, 8.3%). Resistance profiling to different antibiotic classes revealed that all isolates (eight) were resistant to multiple antibiotics tested by us. All isolates were resistant to β-lactams and fluoroquinolones. One strain of <i>E. coli</i> exhibited intermediate resistance to quinolone and penicillin. All strains were categorized as multidrug-resistant. GSE showed antibacterial activity against all isolates.<h4>Conclusions</h4>Wanting to deepen our understanding of the microorganisms that can infect ball pythons and recognizing that all isolated bacteria have zoonotic potential, this paper highlights some common issues faced by exotic animal owners and suggests that treatments should also include the use of essential oils. *[CC BY — Open Access, verbatim with attribution.]*

- PMID 40218366 (2025, Animals : an open access journal from MDPI) — Chains of Commerce: A Comprehensive Review of Animal Welfare Impacts in the International Wildlife Trade.. Abstract (opening): The commercial wildlife trade involves billions of animals each year, consumed for various purposes, including food, fashion, entertainment, traditional medicine, and pets. The experiences of the animals involved vary widely, with negative welfare states being commonplace. To highlight the broad scope of animal welfare impacts across the commercial wildlife trade, we present ten case studies featuring a range of species traded globally for different purposes: (1) Ball pythons captured and farmed to serve as pets; (2) Zebrafish captive bred to serve as pets; (3) African Grey Parrots taken from the wild for the pet industry; (4) Sharks de-finned for traditional medicine; (5) Pangolins hunted for traditional medicine; (6) Crickets farmed for food and feed; (7) Frogs wild-caught for the frog-leg trade; (8) Crocodilians killed for their skins; (9) Lions farmed and killed for tourism; and (10) Elephants held captive for tourism. The case studies demonstrate that wild animals commercially traded can suffer from negative welfare states ranging from chronic stress and depression to frustration and extreme hunger. The individuals involved range from hundreds to billions, and their suffering can last a lifetime. Given the welfare issues identified and the growing recognition and scientific evidence for animal sentience, we propose reducing and redirecting consumer demand for these consumptive wildlife practices that negatively impact animals. *[CC BY — Open Access, verbatim with attribution.]*
