To better understand the epidemiology of C. psittaci in Victoria, Australia, we conducted opportunistic sampling of more than 400 wild and captive birds presented to the Australian Wildlife Health Centre at Zoos Victoria's Healesville Sanctuary for veterinary care between December 2014 and December 2015. Samples were screened for the presence of chlamydial DNA using quantitative PCR, and positive samples were subjected to multilocus sequence typing analysis. The results showed a significantly higher prevalence of infection in captive birds (8%; 9/113) compared to wild birds (0.7%; 2/299). Multilocus sequence typing analysis revealed that C. psittaci sequence type 24 was detected in both wild and captive birds in the local region, while C. psittaci sequence type 27 was detected for the first time in an Australian avian host. The generally low prevalence of C. psittaci detection points to a generally low zoonotic risk to veterinary and support staff, although this risk may be higher when handling captive birds, where the prevalence of C. psittaci infection was almost 10-fold higher. Even with low rates of C. psittaci detection, appropriate hygiene and biosecurity practices are recommended due to the serious human health implications of infection with this pathogen.","PeriodicalId":22805,"journal":{"name":"The Journal of Wildlife Diseases","volume":"71 1","pages":"16 - 26"},"PeriodicalIF":0.0,"publicationDate":"2020-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84263078","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}

Ahlstrom","doi":"10.7589/2019-04-099","DOIUrl":"https://doi.org/10.7589/2019-04-099","url":null,"abstract":"Abstract: The proliferation of antibiotic-resistant bacteria in the environment has potential negative economic and health consequences. Thus, previous investigations have targeted wild animals to understand the occurrence of antibiotic resistance in diverse environmental sources. In this critical review and synthesis, we summarized important concepts learned through the sampling of wildlife for antibiotic-resistant indicator bacteria. These concepts are helpful for understanding dissemination of resistance through environmental pathways and helping to guide future research efforts. Our review begins by briefly introducing antibiotic resistance as it pertains to bacteria harbored in environmental sources such as wild animals. Next, we differentiate wildlife from other animals in the context of how diverse taxa provide different information on antibiotic resistance in the environment. In the third section of our review, we identify representative research and seminal works that illustrate important associations between the occurrence of antibiotic-resistant bacteria in wildlife and anthropogenic inputs into the environment. For example, we highlight numerous investigations that support the premise that anthropogenic inputs into the environment drive the occurrence of antibiotic resistance in bacteria harbored by free-ranging wildlife. Additionally, we summarize previous research demonstrating foraging as a mechanism by which wildlife may be exposed to anthropogenic antibiotic resistance contamination in the environment. In the fourth section of our review, we summarize molecular evidence for the acquisition and dissemination of resistance among bacteria harbored by wildlife. In the fifth section, we identify what we believe to be important data gaps and potential future directions that other researchers may find useful toward the development of efficient, informative, and impactful investigations of antibiotic-resistant bacteria in wildlife. Finally, we conclude our review by highlighting the need to move from surveys that simply identify antibiotic-resistant bacteria in wildlife toward hypothesis-driven investigations that: 1) identify point sources of antibiotic resistance; 2) provide information on risk to human and animal health; 3) identify interventions that may interrupt environmentally mediated pathways of antibiotic resistance acquisition and transmission; and 4) evaluate whether management practices are leading to desirable outcomes.","PeriodicalId":22805,"journal":{"name":"The Journal of Wildlife Diseases","volume":"15 1","pages":"1 - 15"},"PeriodicalIF":0.0,"publicationDate":"2020-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79618001","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}

Information on the life cycle and epidemiology of pseudaliids is very scarce and mostly concerns species that infect coastal or inshore cetaceans. Available evidence indicates that some pseudaliids are vertically transmitted to the host, whereas others are acquired via infected prey. We documented pseudaliid infections in an oceanic cetacean, the striped dolphin (Stenella coeruleoalba) in the western Mediterranean, and investigated the possibilities of vertical vs. horizontal transmission and the potential influence of host body size, sex, and season on infection levels. We found two species of lungworm in 87 dolphins that stranded along the Spanish Mediterranean coast between 1987 and 2018. One or two larvae of Stenurus ovatus were found in three adult dolphins. Larger numbers of larvae and adults of Skrjabinalius guevarai were collected in 51 dolphins, including unweaned calves. These observations suggested that Skrjabinalius guevarai could be vertically transmitted. The abundance of Skrjabinalius guevarai increased significantly with host size, which suggested that it could be trophically transmitted, as well, with larger hosts consuming more infected prey. Infection levels peaked in spring, outside of the calving season, which is likely a reflection of a seasonal shift in dolphin diet. In summary, results indicate that Skrjabinalius guevarai was capable of both vertical and horizontal transmission, but future research should be directed at clarifying the potential mechanics behind transmission and intermediate hosts.","PeriodicalId":22805,"journal":{"name":"The Journal of Wildlife Diseases","volume":"23 1","pages":"186 - 191"},"PeriodicalIF":0.0,"publicationDate":"2020-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82752650","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}

Our objective was to optimize a noninvasive method of oral sampling from semicaptive NP in Peru. We offered 40 NP at Taricaya Rescue Centre in Madre de Dios, Peru ropes coated in various attractants and measured variables (acceptance of the rope, chewing time, and volume of fluid eluted from ropes) that may affect sample acquisition and quality. We preserved samples by direct freezing in liquid nitrogen or by storing samples in RNA stabilization reagent at room temperature. Sample integrity was measured by testing for mammalian cytochrome b with the use of conventional PCR. The NP successfully chewed on a rope in 82% (125/152) of trials. Overall sample integrity was high, with 96% (44/46) of samples (both directly frozen and stored in stabilization reagent) testing positive for cytochrome b. The number of times that an individual NP was exposed to the rope procedure and NP age were associated with higher acceptance rates and the NP successfully chewing on the rope. We conclude that ropes serve as a feasible noninvasive method of obtaining oral samples from NP at rescue centers and could be used in future studies to evaluate population genetics and for pathogen surveillance for population health monitoring.","PeriodicalId":22805,"journal":{"name":"The Journal of Wildlife Diseases","volume":"1 1","pages":"192 - 196"},"PeriodicalIF":0.0,"publicationDate":"2020-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89373245","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}

At its essence, this is a history book that chronicles the role and evolution of state wildlife agencies (divisions, bureaus) in the management and conservation of wildlife in the US. I am also a wildlife biologist with nearly 40 yr of experience, so I appreciate the authors’ and editor’s efforts to capture this aspect of our wildlife management and conservation heritage in a single volume. However, why should a reader of the Journal of Wildlife Diseases add to their library a history book that has but one brief chapter dedicated to wildlife disease management? As underscored in this book, for the first 150 yr the primary emphasis of state wildlife agencies was on regulating harvest of game and furbearing species. Since then, the addition of several other topics has formed a more diversified mosaic of issues within the present-day mission of the state wildlife agency, such as habitat, nongame species, threatened and endangered species, invasive species, human–wildlife conflicts, and human dimensions. Oh, yes, add to this list attention to wildlife diseases as an integral area of focus for many state wildlife agencies. Brucellosis, chronic wasting disease, epizootic hemorrhagic disease, bovine tuberculosis, and avian influenza are among the notable disease catalysts behind this broadened interest. As poignantly emphasized in the chapter on State Management of Wildlife Disease, state wildlife agencies will be challenged in the future to provide expertise to conduct wildlife disease investigations and control programs in nearly all facets of wildlife management and conservation. In the face of changing landscapes, climate, and public attitudes among a diversifying constituency, greater capacity among state agency responsiveness on behalf of wildlife health seems a safe bet! Yet it is not the chapter on wildlife disease management that is driving my recommendation that readers of the Journal of Wildlife Diseases consider adding this book to their libraries. Although this brief chapter is an integral part of this book, it is the topics covered in other chapters that drive my recommendation, including the public trust doctrine and the legal basis for state wildlife management, the role of human dimensions, research, and human–wildlife conflicts. Collectively, these 14 chapters provide readers with a more comprehensive understanding of the state wildlife agency regulatory responsibility and niche for providing the best management practices across a diverse range of taxa under their purview, which by default includes considerations for wildlife health. For many, this book will not likely be a sitdown and read cover-to-cover experience. Rather, it fits more as an important one-stop shopping reference for the milestones and contributions of state wildlife agencies to date, with adequate references within each chapter","PeriodicalId":22805,"journal":{"name":"The Journal of Wildlife Diseases","volume":"15 1","pages":"255 - 256"},"PeriodicalIF":0.0,"publicationDate":"2020-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84736292","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}

Infected humans, dogs (Canis lupus familiaris), and nonhuman primates may remain asymptomatic or may develop Chagas disease, most commonly characterized by lymphoplasmacytic myocarditis with myocardial degeneration and fibrosis, ultimately resulting in heart failure. Although wildlife species have important roles as sylvatic reservoirs, investigations into the pathology of T. cruzi in wildlife are limited to a few studies documenting histologic lesions in opossums (Didelphis spp.) and raccoons (Procyon lotor). Pathology in coyotes (Canis latrans) has not, to our knowledge, been described, despite their recognition as a reservoir and close genetic relationship to domestic dogs. Our objectives were to perform a detailed, comparative cardiac pathology study of sympatric, naturally infected coyotes and raccoons, to characterize the overall T. cruzi infection prevalence in the heart and blood of each species via PCR, and to identify infecting discrete typing units (DTUs). We sampled hunter-harvested coyotes (n=120) and raccoons (n=24) in a 28 county region of central and south Texas, US. Raccoons were significantly more likely to have positive PCR results (P<0.001) with a prevalence of 62% (15/24), comprising DTU TcIV exclusively, with mild to no evidence of cardiac pathology. In contrast, coyotes had a lower infection prevalence (8%, 10/120), comprising DTU TcI exclusively, with lymphoplasmacytic myocarditis observed in four of the six PCR-positive animals. Many raccoons had PCR-positive blood and heart tissue simultaneously, supporting previous reports that raccoons maintain parasitemia into chronic stages of infection; in contrast, none of the PCR-positive coyotes were positive in both heart and blood. Our findings demonstrate marked differences in T. cruzi infection dynamics between coyotes and raccoons, with important implications for reservoir potential and their role in transmission cycles.","PeriodicalId":22805,"journal":{"name":"The Journal of Wildlife Diseases","volume":"123 1 1","pages":"134 - 144"},"PeriodicalIF":0.0,"publicationDate":"2020-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77573044","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 this experimental study, we compared the susceptibility of mule deer to FMD virus (FMDV) serotype O to that of cattle (Bos taurus). We also determined the potential for intra- and interspecies transmission of FMDV serotype O in mule deer and cattle, and assessed conventional laboratory tests in their ability to detect FMDV in mule deer. Two mule deer and one steer were each infected by intraepithelial tongue inoculation with 10,000 bovine tongue infective doses of FMDV, strain O1 Manisa.

All mule deer (n=14) and cattle (n=6) developed clinical signs and lesions consistent with FMDV infection. Deer had a high prevalence of myocarditis and high mortality. Virus was transmitted between mule deer, from cattle to mule deer, and from mule deer to cattle.
