Abstract Koala populations are in catastrophic decline certain eastern Australian regions. Spanning from 1997–2013, a database derived wildlife hospitals southeast Queensland with N = 20,250 entries was classified by causes of morbidity and mortality. A total 11 aetiologies were identified, chlamydiosis, trauma, wasting being most common. The clinical diagnosis at submission varied significantly over the observation period. Combinations observed 39% koalas submitted, chlamydiosis frequently...

Per- and polyfluoroalkyl substances (PFAS) are persistent synthetic contaminants that pervasive in the environment. Toxicity resulting from elevated PFAS concentrations wildlife has been studied, yet evidence of their accumulation, developmental toxicity maternal offloading egg-laying species is limited. Here we show freshwater short-necked turtles (Emydura macquarii macquarii) exposed to biological impact on oviducal eggs. Total were determined serum adult females harvested eggs collected...

The spread throughout several states and was diagnosed for time California on May 11, 2020, a black-tailed jackrabbit (Lepus californicus). day, Department Food Agriculture (CDFA) issued an order banning entrance into lagomorph species their products from any state which had been detected last 12 mo. RHDV2 is threat to wild...

Per- and polyfluoroalkyl substances (PFAS) are environmentally persistent pervasive. Understanding the toxicity of PFAS to wildlife is difficult, both due complexity biotic abiotic perturbations in taxa under study practical ethical problems associated with studying impacts environmental pollutants on free living wildlife. One avenue inquiry into effects pollutants, such as PFAS, assessing impact host gut microbiome. Here we show microbial composition biochemical functional outputs from...

Turtles are a potential sentinel species of aquatic ecosystem health as they inhabit ecosystems, long lived, and potentially have high exposure to anthropogenic chemicals via food water. This study investigated per- polyfluoroalkyl substances (PFAS) tissue partitioning in female Emydura macquarii turtle, the maternal offloading into eggs then hatchlings well accumulation PFAS male serum. Significantly higher levels perfluorosulfonic acids (PFSAs) perfluorocarboxylic (PFCAs) were measured...

The development of human uterine cancer is a complex process involving the abnormal expression tumor suppressors, such as PTEN, ARID1A, and TP53; mismatch repair protein MSH6; transcription factors, PAX2 PAX8. functional changes that lead to adenocarcinoma in pet rabbits are not fully understood despite frequent occurrence this condition species. Thus, an immunohistochemical analysis was performed visualize pattern carcinogenesis-related molecules surgical biopsy specimens from 56...

Abstract Koalas are an iconic Australian marsupial undergoing precipitous population reduction in South-East Queensland from complex interacting threats. To investigate the causes of death and interaction comorbidities with demography koalas, a large scale, high-throughput prospective necropsy survey was conducted spanning 2013–2016. During this period, 519 necropsies were 155 young/subadult 235 mature, 119 old koalas 10 unknown age. Similar numbers males females assessed. Trauma infectious...

Per-and polyfluoroalkyl substances (PFAS) are a growing concern for humans, wildlife, and more broadly, ecosystem health. Previously, we characterised the microbial biochemical impact of elevated PFAS on gut microbiome freshwater turtles (Emydura macquarii macquarii) within contaminated catchment in Queensland, Australia. However, understanding impacts this species other aquatic organisms is still very limited, especially at host–gut molecular interaction level. To end, present study aimed...

Per- and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants known to pose significant risks human wildlife health. Freshwater turtles (Emydura macquarii macquarii), as long-lived species inhabiting aquatic ecosystems, particularly vulnerable PFAS bioaccumulation. This study investigated the multifaceted impact of contamination on these turtles, focusing metabolic disruptions, reproductive success, hatchling health, population impacts. Comprehensive analyses,...

Summary Ants provide variable protection against herbivores to ant‐plants (i.e. myrmecophytes and myrmecophiles). The ways in which dynamically adjust both their direct (chemical physical) indirect (biotic) defences response varying levels of herbivory are not well understood. We experimentally generated a broad range ant‐attendance pressures tropical myrmecophyte, C ordia nodosa, allowed exploration the inducibility interactions between resistance traits. In increased herbivory, host plants...

The prevalence of five avian haemoparasite groups was examined for effects on health and associations with extrinsic factors. Overall, 786 samples were from six sites in two Georgia (USA) watersheds, during breeding non-breeding periods 2010 2011. Among the four most commonly infected species, Haemoproteus significantly higher Northern Cardinals (Cardinalis cardinalis) compared to Indigo Buntings (Passerina cyanea) Tufted Titmice (Baeolophus bicolor) while White-throated Sparrows...

The Quichua porcupine (Coendou quichua) is a neotropical rodent with uncertain taxonomic and conservation status. Two porcupines severe hyperkeratosis alopecia were found in the Magdalena River Basin of Colombia. Sarcoptes scabiei, mite causing mange, disease carried mainly by domestic animals, was confirmed via parasitological molecular methods. This first report mange to date. population-level impact Coendou spp., related mammals predators Colombia might represent threat needs further...

Despite relevance for conservation, no study to date has focused on evaluating geriatric diseases in dunnarts. This describes pathology findings a group 36 captive-born, mostly that failed produce offspring over periods. A total 20 females 16 males were submitted postmortem examination, with ages ranging...

Leptospirosis is a widespread zoonotic disease with well-established impacts on human health in tropical and subtropical regions. Although Leptospira spp. are known to readily infect many wildlife species, the understanding of interspecies climatic variability patterns infection Neotropical mammals limited. To improve this interplay, 85 representing 17 species were sampled from four Colombian zoos along gradient. Prevalence 21 primary serovars against interrogans was determined using...

Gastrointestinal parasites colonizing the mammalian gut influence host immune system and health. Parasite infections, mainly helminths, have been studied intensively in both humans non-human animals, but relatively rarely within a conservation framework. The Udzungwa red colobus monkey (Procolobus gordonorum) is an endangered endemic primate species living Mountains of Tanzania, global biodiversity hotspot. Since this highly sensitive to human disturbance, here we investigate whether habitat...

To determine the relative importance of mortality factors for birds and to assess patterns in avian over time, we retrospectively examined data submitted Southeastern Cooperative Wildlife Disease Study (SCWDS; http://vet.uga.edu/scwds ), US, from 1976 2012. During this period, SCWDS, a wildlife diagnostic laboratory, received 2,583 wild bird specimens, taxonomic orders Apodiformes, Caprimulgiformes, Cuculiformes, Passeriformes, Piciformes, originating 22 states. Data 2,001 these were...

Mammals provide an important ecological habitat or niche space to microbial diversity, protistans (or protozoans) and metazoan parasites that can have profound effects on both human animal health. Thus, understanding the status of mammalian species as hosts for pathogens holds relevance, especially during this time anthropogenic environmental change. Despite great diversity in mammal fauna Colombia, data literature occurrence these mammals are scarce widely scattered. In order understand...

Leptospirosis is a zoonotic disease with worldwide distribution caused by pathogenic Leptospira spp. Pathogenic are shed in urine of infected hosts and transmitted via ingestion contaminated food or water, inoculation, inhalation aerosolized urine, absorption through mucous membranes. particular concern tropical subtropical regions such as Barranquilla, Colombia. Recent reports indicate that rodents, dogs, humans have high leptospiral seroprevalence; amongst zoo mammals, nonhuman primates...
