Rabid bats showed weight loss, aggression, increased vocalization, hypersalivation, and refusal of food. Antigenic typing and virus sequencing confirmed that all five bats were infected with an identical rabies virus variant that circulates in E. fuscus in the US. Two bats with no signs of rabies virus infection were seropositive for rabies virus-neutralizing antibodies; the brains of these bats had no detectable viral proteins by the direct fluorescence antibody test. We suspect bat-to-bat transmission of rabies virus occurred among our bats because all rabies-infected bats were confined to the cage housing the index case and were infected with viruses having identical sequences of the entire rabies nucleoprotein gene. This outbreak illustrates the risk of rabies virus infection in captive bats and highlights the need for researchers using bats to assume that all wild bats could be infected with rabies virus.","PeriodicalId":22805,"journal":{"name":"The Journal of Wildlife Diseases","volume":"33 1","pages":"197 - 202"},"PeriodicalIF":0.0,"publicationDate":"2020-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73881596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Batrachochytrium dendrobatidis (BD) is a pathogen associated with amphibian population declines but also occurs without causing mass mortalities. The impact of BD in populations without associated declines is not well understood, and food abundance could play a role in determining the magnitude of its effects. We exposed American toad (Anaxyrus americanus), northern leopard frog (Lithobates pipiens), and cricket frog (Acris blanchardi) metamorphs to BD under low or high food treatments. Overall, anuran species responded differently to BD exposure and the combined effect of BD exposure and food abundance was additive. American toad survival was lowered by BD exposure and low food availability. Based on these results, we developed a population model for American toads to estimate how reductions in survival could influence population growth. We found that BD could reduce population growth by 14% with high food availability and 21% with low food availability. In contrast, survival of northern leopard frogs was high across all treatments, but their growth was negatively impacted by the additive effects of BD exposure and low food availability. Cricket frog growth and survival were unaffected by BD exposure, suggesting that this species is not sensitive to the effects of this pathogen in terms of growth and survival across environments of different quality in the time period examined. Our results showed that low food availability additively increased the species-specific lethal and sublethal impacts of BD on hosts, which could have implications for long-term host population dynamics.","PeriodicalId":22805,"journal":{"name":"The Journal of Wildlife Diseases","volume":"2 1","pages":"338 - 349"},"PeriodicalIF":0.0,"publicationDate":"2019-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73114580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These events are often under-diagnosed and, when observed, predictive health factors are unavailable prior to death. At Kickapoo State Park in central Illinois, USA, ranaviruses caused observed mortality events in amphibians and chelonians in 2014 and 2015. Following these outbreaks, eastern box turtles (n=36) were affixed with radio transmitters and temperature data loggers to obtain repeated location and temperature data from spring 2016–spring 2018. Bimonthly, samples of blood and oral and cloacal swabs were collected to investigate health parameters (hematology and cytokine transcription) and presence of multiple pathogens. Deaths of instrumented turtles occurred in 2016 (n=5), 2017 (n=15), and 2018 (n=2). The largest single die-off occurred in February 2017 (n=7). Seventeen turtles were necropsied and multiple pathologic processes were identified, most frequently decreased adipose stores (n=6). Two turtles had pathologic findings consistent with multisystemic inflammation. In addition, infectious pathogens were identified in turtles prior to death, but no single agent was associated with each mortality event. Ranavirus was not detected in any turtle. Hot spot analysis revealed spatial clustering at the center and edges of the study area for body temperature as well as for relative cytokine transcription of interleukin-1 beta, tumor necrosis factor alpha, and interleukin-10 associated with turtle death. Though no single causal factor could be identified, the information from this mortality event can direct future chelonian mortality investigations by providing baseline longitudinal data prior to death and in surviving turtles.","PeriodicalId":22805,"journal":{"name":"The Journal of Wildlife Diseases","volume":"24 1","pages":"306 - 315"},"PeriodicalIF":0.0,"publicationDate":"2019-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90475883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In May 2011, six fox squirrels (Sciurus niger) in Clinton State Park, Kansas, US were euthanized after exhibiting clinical signs of neurologic disease. Postmortem examination of two squirrels revealed that these individuals died of Baylisascaris larva migrans, which resulted in meningoencephalitis and variable pneumonia and myocarditis. Fecal flotation of raccoon (Procyon lotor) feces collected in the area revealed Baylisascaris sp. ova, presumably Baylisascaris procyonis, in one of nine samples. Additional fox squirrel carcasses were submitted for diagnostic evaluation from eastern Kansas for 1 yr following the Baylisascaris sp. outbreak. This monitoring unexpectedly resulted in the detection of Francisella tularensis, the zoonotic pathogen that causes tularemia, in two fox squirrels. The increased attention to fox squirrel mortalities prompted by the outbreak of Baylisascaris sp. larva migrans revealed cases of tularemia that may not have been otherwise detected. Although F. tularensis is endemic in Kansas, the current distribution and prevalence of B. procyonis in raccoons and other hosts in Kansas are poorly understood. This yearlong mortality investigation illustrated the importance of wildlife health monitoring as a means of assessing public health risks, especially during unusual wildlife mortality events.","PeriodicalId":22805,"journal":{"name":"The Journal of Wildlife Diseases","volume":"181 1","pages":"457 - 461"},"PeriodicalIF":0.0,"publicationDate":"2019-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80239106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, over the last 25 yr, sarcoptic mange has been increasingly reported in black bears in the northeastern US. Syndromic monitoring is the most common surveillance approach for mange in bears, but tools to monitor exposure to Sarcoptes scabiei in bear populations have not been thoroughly evaluated under field conditions. In this study, we validated a commercially available enzyme-linked immunosorbent assay (ELISA), designed to detect antibodies against S. scabiei in dogs, for use in black bears with a sensitivity and specificity of 95.6% and 96.6%, respectively. To further examine the performance of this assay, serial serum samples from seven black bears with confirmed sarcoptic mange were collected posttreatment to determine the persistence of detectable antibody response with the ELISA. Antibodies in black bears waned to below the limit of detection between 4 and 14 wk, suggesting that serology studies might underestimate the number of exposed black bears after antibodies have waned. State-wide serosurveys in Pennsylvania from hunter-harvested black bears in 2017 and 2018 showed a significant difference in seroprevalence between regions with high occurrence of mange (mean seroprevalence 6.7%, range of 6.6–6.8%) and low occurrence of mange (no seropositive black bears were detected). Within Pennsylvania, these data indicate that the geographic distribution of exposure to S. scabiei, based on serologic testing, generally reflects the distribution of overt disease, as determined by syndromic surveillance. Collectively, these results indicate the evaluated ELISA is an effective tool for monitoring S. scabiei exposure in bear populations and provides the framework for additional studies regarding sarcoptic mange epidemiology in black bears.","PeriodicalId":22805,"journal":{"name":"The Journal of Wildlife Diseases","volume":"22 1","pages":"350 - 358"},"PeriodicalIF":0.0,"publicationDate":"2019-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90504847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
