Descriptive Epidemiology of Bovine Tuberculosis in Michigan (1975–2010)‎ : Lessons Learned

Abstract EN

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.
