Abstract (opening): Both avian and nonavian reptiles excrete excess nitrogen in solid form─colloquially termed \"urates\"─as an evolutionary adaptation that aids in water conservation. Yet, there are many open questions regarding the composition, structure, and assembly of these biogenic materials. Here, analyses of urate excretions from ball python (<i>Python regius</i>) and 20 other reptile species reveal a clever and highly adaptable system employed to handle both nitrogenous waste and salts. Primitive species excrete urates consisting of 1-10 μm microspheres of turbostratic uric acid monohydrate (UAM) nanocrystals. The nanocrystals' high surface area and ionizable nature provides a platform to coeliminate substoichiometric concentrations of various salts through surface-ion pairing. In contrast, the granular urates produced by species from more advanced snake lineages are phase mixtures consisting of predominantly ammonium urate hydrate (AUH) and smaller amounts of other crystalline forms. Identification of microspheres as a minor but highly soluble component of these excretions suggests their likely role as reactive precursors to AUH, a hypothesis supported by in vitro experiments. Importantly, this points to a previously unrecognized physiologic function of uric acid, namely the ability to sequester ammonia by transforming it into a solid. The potential implications of this function in other species are discussed. *[CC BY — Open Access, verbatim with attribution.]*\n  Source: https://pubmed.ncbi.nlm.nih.gov/41123193/\n- **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.]*\n  Source: https://pubmed.ncbi.nlm.nih.gov/40218366/\n- **PMID 40558139 (2025, Antibiotics (Basel, Switzerland))** — Antibacterial Activity of Some Essential Oils/Herbal Extracts Against Bacteria Isolated from Ball Pythons (&lt;i&gt;Python regius&lt;/i&gt;) 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.]*\n  Source: https://pubmed.ncbi.nlm.nih.gov/40558139/\n\nSource text: `pdf-raw/evidence/europepmc_ball_python_nutrition_2026-08-01.txt` (Europe PMC first-hand abstracts, pulled 2026-08-01).\n\n## License & attribution\n\nMixed licensing per COPYRIGHT_POLICY §3: Open Access (CC BY / CC BY-NC /\nCC BY-NC-ND) studies are reproduced verbatim with attribution under their specific\nCC license; non-Open-Access studies are paraphrased as derived fact summaries\n(numbers and proper nouns preserved, sentences rewritten).
