Figure 2

Percent prevalence of Mycobacterium bovis–positive coyotes (Canis latrans) and white-tailed deer (Odocoileus virginianus) in Montmorency, Alpena, Alcona, and Oscoda Counties, Michigan, 2003–2005. Prevalence estimates for white-tailed deer are expressed as a mean calculated from discrete sampling periods conducted in 2003, 2004, and 2005. Error bars for coyote estimates represent the standard error of the mean calculated across townships for each county. Estimates of M. bovis prevalence for white-tailed deer were not available for individual townships; standard errors were not calculated for counties.
