Serologic Surveillance of Anthrax in the Serengeti Ecosystem, Tanzania, 1996–2009
Figure 3. 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 expected.
