Social Structure Defines Spatial Transmission Of African Swine Fever In Wild Boar, Kim M. Pepin, Andrew J. Golnar, Tomasz Podgórski
Social Structure Defines Spatial Transmission Of African Swine Fever In Wild Boar, Kim M. Pepin, Andrew J. Golnar, Tomasz Podgórski
United States Department of Agriculture Wildlife Services: Staff Publications
The spatial spread of infectious disease is determined by spatial and social processes such as animal space use and family group structure. Yet, the impacts of social processes on spatial spread remain poorly understood and estimates of spatial transmission kernels (STKs) often exclude social structure. Understanding the impacts of social structure on STKs is important for obtaining robust inferences for policy decisions and optimizing response plans. We fit spatially explicit transmission models with different assumptions about contact structure to African swine fever virus surveillance data from eastern Poland from 2014 to 2015 and evaluated how social structure affected inference of …
Surveillance Of Culex And Aedes Mosquitoes In Lincoln, Lancaster County, Nebraska, William Noundou
Surveillance Of Culex And Aedes Mosquitoes In Lincoln, Lancaster County, Nebraska, William Noundou
Department of Entomology: Dissertations, Theses, and Student Research
In 2018, West Nile virus (WNV) was identified as the leading cause of mosquito-borne disease in the continental United States. In response to this very serious problem, the Lincoln-Lancaster County Public Health Department (LLCHD) reinforced their mosquito surveillance program, which constitutes one of the best available tools to fight against this serious threat to human health. The objectives of this study were to 1) expand knowledge of the activity and relative abundance of mosquito communities in understudied areas and 2) evaluate differences in mosquito communities by urban and rural location, especially focusing on known vector species. A total of 6 …

The ecology of infectious disease in wildlife has become a pivotal theme in animal and public health. Studies of infectious disease ecology rely on robust surveillance of pathogens in reservoir hosts, often based on serology, which is the detection of specific antibodies in the blood and is used to infer infection history. However, serological data can be inaccurate for inference to infection history for a variety of reasons. Two major aspects in any serological test can substantially impact results and interpretation of antibody prevalence data: cross-reactivity and cut-off thresholds used to discriminate positive and negative reactions. Given the ubiquitous use …
Yersinia Pestis: Examining Wildlife Plague Surveillance In China And The Usa, Sarah N. Bevins, John A. Baroch, Dale L. Nolte, Min Zhang, Hongxuan He
Yersinia Pestis: Examining Wildlife Plague Surveillance In China And The Usa, Sarah N. Bevins, John A. Baroch, Dale L. Nolte, Min Zhang, Hongxuan He

Plague is a zoonotic disease caused by the bacterium Yersinia pestis Lehmann and Neumann, 1896. Although it is essentially a disease of rodents, plague can also be transmitted to people. Historically, plague has caused massive morbidity and mortality events in human populations, and has recently been classified as a reemerging disease in many parts of the world. This public health threat has led many countries to set up wild and domestic animal surveillance programs in an attempt to monitor plague activity that could potentially spill over into human populations. Both China and the USA have plague surveillance programs in place, …
Didactic Lessons Derived From The Shoshone River Skunk Rabies Epizootic, Craig A. Ramey, Kenneth H. Mills, Justin W. Fischer, Robert G. Mclean
Didactic Lessons Derived From The Shoshone River Skunk Rabies Epizootic, Craig A. Ramey, Kenneth H. Mills, Justin W. Fischer, Robert G. Mclean

Studying the lower Shoshone River Basin’s (SRB) striped skunk (Mephitis mephitis) rabies 6-year epizootic in northwestern Wyoming has produced four didactic lessons. First, physiographic changes by settlers circa 1900 affected its zoogeography by creating a canal system for irrigating crops originating at Buffalo Bill Reservoir (BBR). The resulting landscape changes increased agricultural lands and skunk habitat eightfold between the valley’s steep gravel benches. The valley was historically free of skunk rabies until the epizootic’s index case in August 1988. Second, human intervention began when the Bighorn County Predator Board (BCPB) proactively implemented rabies trapping surveillance and depopulation programs …

A rabies epizootic occurred in striped skunks from 1988-1993 in a previously rabies-free area of northwestern Wyoming. USDA APHIS Wildlife Services (WS) cooperated with state and local officials by providing a rabies monitoring and depopulation program starting in 1990. Wyoming WS asked for assistance in 1991 from the National Wildlife Research Center (NWRC) to analyze the epizootic’s movements. The goal was to address the public’s concerns about their health and safety and that of their domestic animals and livestock. All rabid skunks were diagnosed by the Wyoming State Veterinary Laboratory (WSVL) using standardized fluorescent antibody testing of brain tissues. The …
