Seroprevalence of anthrax in sampled wildlife populations from Serengeti National Park (white bars) and Ngorongoro Crater (gray bars), Tanzania, 1996–2009. Error bars indicate 95% confidence intervals. Sample sizes used to calculate seroprevalence are indicated above the bars. Hyenas were not sampled in Ngorongoro Crater. Seropositive zebras were not detected; error bars indicate 95% confidence intervals based on a binomial distribution of the sample size and the seropositivity range that can be
