牛结核分枝杆菌（Mycobacterium bovis）是美国密歇根州东北部下半岛的5个县（阿尔科纳、阿尔皮纳、蒙特莫伦西、奥斯科达和普雷斯克岛）的散养白尾鹿（Odocoileus virginianus）的地方病。密歇根州野生动物结核病宿主的存在和牛（Bos taurus）中bTB的发病率导致密歇根州失去了其无bTB认证的地位。随后的野生动物监测计划确定了相对较高的疾病患病率在郊狼（犬latrans），产生兴趣，他们的潜力作为一个哨兵物种，以检测白尾鹿的bTB患病率。我们的目标是建立一个经验基础，为未来的监测，管理和建模工作产生关于bTB感染的空间流行病学的假设在郊狼。虽然土狼的家范围大小的变化可能会混淆试图在空间上相关的疾病的发病率在哨兵和宿主物种在一个精细的尺度，相邻土狼的家范围之间的重叠区（OZs）可能是适当的样本单元空间相关的疾病流行在土狼和白尾鹿。由于重叠归属范围通常被配置在资源丰富的周围（例如，小型哺乳动物和白尾鹿）木材管理补丁，OZ集中在一个相对较小的区域相邻群体之间的空间互动。此外，有一个直接的相互作用的概率和这些补丁的空间色散之间的关系。后一个发现提供了一个有用的度量纳入未来的努力，开发空间明确的模型的bTB动态。建模工作，然后可以用来作为一个基础，预测在集中管理的森林景观的变化的流行病学后果。
Mycobacterium bovis, the causative agent of bovine tuberculosis (bTB), is endemic in free-ranging white-tailed deer (Odocoileus virginianus) in 5 counties (Alcona, Alpena, Montmorency, Oscoda, and Presque Isle) in the northeastern Lower Peninsula of Michigan, USA. The presence of a wildlife reservoir of tuberculosis in Michigan and the incidence of bTB in cattle (Bos taurus) resulted in Michigan losing its bTB accredited-free status. Subsequent wildlife surveillance programs identified relatively high disease prevalence in coyotes (Canis latrans), generating interest in their potential to serve as a sentinel species to detect bTB prevalence in white-tailed deer. Our goal was to develop an empirical basis for generating hypotheses about the spatial epidemiology of bTB infection in coyotes for future surveillance, management, and modeling efforts. Though variation in coyote home-range size may confound attempts to spatially correlate the incidence of disease in the sentinel and host species at a fine scale, overlap zones (OZs) between adjacent coyote home ranges may be the appropriate sample unit for spatially correlating disease prevalence in coyotes and white-tailed deer. Because overlapping home ranges are generally configured around resource rich (e.g., small mammals and white-tailed deer) timber management patches, the OZ concentrates spatial interaction between adjacent groups in a relatively small area. Furthermore, there is a direct relationship between interaction probabilities and the spatial dispersion of those patches. The latter finding provides a useful metric to incorporate into future efforts to develop spatially explicit models of bTB dynamics. Modeling efforts can then be used as a foundation to predict the epidemiological ramifications of alterations in intensively managed forested landscapes.
