Urban Magpies Frequently Feed on Coyote Scats and May Spread an Emerging Zoonotic Tapeworm
AbstractAllocoprophagy, in which animals feed on the feces of other individuals or species, has been little studied in vertebrates, despite its relevance to parasite transmission. These relationships may be especially important in cities, where animal density, disease incidence, and spatial overlap of humans and wildlife increase. Our goal was to document the incidence and predictors of coprophagy by black-billed magpies (Pica hudsonia) at coyote (Canis latrans) scats in Edmonton, Canada. We detected scats by following coyote trails and recorded whether coprophagy had occurred. We used multiple logistic regression to deter...

Serological Survey for Three Canine Viruses in Brazilian Wild Carnivores
AbstractWe evaluated the presence of antibodies against CaHV-1, CDV, and CPV-2 in serum samples from Brazilian wild carnivore species. Nine maned wolves and six crab-eating foxes were tested for CaHV-1 and CDV by virus neutralization test and CPV-2 by hemagglutination inhibition assay. Antibodies to CaHV-1, CDV, and CPV-2 were detected in serum samples of 1 (6.7%), 5 (33.3%), and 10 (66.7%) wild carnivores, respectively. Two maned wolves and one crab-eating fox were seropositive simultaneously for CDV and CPV-2. Antibodies against all viruses were detected in one crab-eating fox. This is the first report of CaHV-1 antibody...

Salmonella enterica Infection of Synanthropic Non-native Geckos in Southern Florida
AbstractWild geckos are a significant source of human salmonellosis. We swabbed the cloacas of 37 non-native synanthropic geckos (Gekko gecko, n = 16;Phelsuma grandis,n = 21) from southern Florida, USA, and assayed swab DNA extracts using quantitative polymerase chain reaction of theinvA gene.Salmonella enterica was detected in both species with a pooled prevalence of 13.5% (5/37; 95% CI 5.3 –27.1%), indicating the potential for zoonotic transmission. Implications for human health in the region are discussed. (Source: EcoHealth)

Orthohantavirus Infection in Two Rodent Species that Inhabit Wetlands in Argentina
AbstractPrevious research conducted in central-east region of Argentina recorded potential orthohantavirus host rodents in diverse environments, but no research has focused particularly on islands, the environments that present the greatest risk to humans. For this reason, the aims of this research were to determine the orthohantavirus host in the rodent community focused on islands of Paran á River Delta, central-east region of Argentina, to identify temporal and spatial factors associated with orthohantavirus prevalence variations, to compare the functional traits of seropositive and seronegative rodents, and to explore...

Metagenomic and Molecular Detection of Novel Fecal Viruses in Free-Ranging Agile Wallabies
This study highlighted the utility of non-invasive sampling as well as the integration of broad-based molecular assays (consensus PCR and next generation sequencing) for monitoring the emergence of potential pathogenic viruses i n wildlife species. Furthermore, the novel marsupial viruses identified in this study will enrich the diversity of knowledge about marsupial viruses, and may be useful for developing diagnostics and vaccines.

Bacterial and Viral Diversity of Didelphid Opossums from Brazil
AbstractMarsupials belonging to theDidelphis genus are widely distributed in the American Continent, andDidelphis albiventris andDidelphis aurita, are common in all of their areas of distribution in Brazil. Here we describe the bacterial and viral diversity of samples from opossums captured in three forest fragments in the State of S ão Paulo, Brazil. Microbiomes from the same body site were more similar across species and sampling sites while oral swabs presented higher bacterial diversity than rectal swabs. We also identified sequences related to bacterial species involved in zoonotic diseases. The detection of pathogen...

Vector-Borne Disease in Wild Mammals Impacted by Urban Expansion and Climate Change
AbstractEcologies of zoonotic vector-borne diseases may shift with climate and land use change. As many urban-adapted mammals can host ectoparasites and pathogens of human and animal health concern, our goal was to compare patterns of arthropod-borne disease among medium-sized mammals across gradients of rural to urban landscapes in multiple regions of California. DNA ofAnaplasma phagocytophilum was found in 1 –5% of raccoons, coyotes, and San Joaquin kit foxes;Borrelia burgdorferi in one coyote, rickettsiae in two desert kit foxes, andYersinia pestis in two coyotes. There was serological evidence of rickettsiae in 14 â€...

Wildlife Consumption, Health, and Zoonotic Disease in China After the Emergence of COVID-19
AbstractThere has been much discussion in the conservation and policy realms of COVID-19 as a zoonotic disease, or a disease transmitted from wildlife to humans. However, wildlife consumption in China is not only a potential source of disease but also a practice embedded in complex beliefs about health. This paper used survey data (N = 974) collected in China in June 2021 to examine attitudes and behaviors related to (a) wildlife consumption, (b) Traditional Chinese Medicine (TCM) and (c) zoonotic risk after the emergence of the COVID-19 pandemic. 40.1% of respondents self-reported that they are less likely to consume ...
