Despite ongoing eradication efforts, bovine tuberculosis (BTB) remains a challenge in Michigan livestock and wildlife. The objectives of this study were to (1) review the epidemiology of BTB in Michigan cattle, privately owned cervids, and wildlife between 1975 and 2010 and (2) identify important lessons learned from the review and eradication strategies. BTB information was accessed from the Michigan BTB Eradication Project agencies. Cattle herds (49), privately owned deer herds (4), and wild white-tailed deer (668) were found infected with BTB during the review period. BTB has occurred primarily in counties located at the northern portion of the state's Lower Peninsula. Currently used BTB eradication strategies have successfully controlled BTB spread. However additional changes in BTB surveillance, prevention, and eradication strategies could improve eradication efforts.
尽管一直在努力根除，但牛结核病（BTB）仍是密歇根州家畜和野生动物面临的一项挑战。本研究的目的是：（1）回顾1975年至2010年间密歇根州牛、私人养殖的鹿科动物和野生动物中牛结核病的流行病学情况；（2）从回顾及根除策略中总结重要经验教训。牛结核病信息来自密歇根州牛结核病根除项目机构。在回顾期内，发现有49个牛群、4个私人养殖鹿群和668只野生白尾鹿感染了牛结核病。牛结核病主要发生在该州下半岛北部的县。目前采用的牛结核病根除策略已成功控制了牛结核病的传播。然而，牛结核病监测、预防和根除策略的进一步改变可能会改善根除工作。
