A cross-sectional study of bovine tuberculosis BTB detected by the comparative intradermal tuberculin test CIDT was conducted in livestock of the Somali region in southeast Ethiopia—in four pastoral associations from January to August 2009. In 94 herds, each of 15 cattle, camels, and goats was tested per herd leading to a total of 1,418 CIDT tested animals, with 421 cattle, 479 camels, and 518 goats. A herd was considered positive if it had at least one reactor. Prevalence per animal species was calculated using a xtgee model for each species. The individual animal prevalence was 2.0% 95% confidence interval CI, 0.5–8.4, 0.4% 95% CI, 0.1–3%, and 0.2% 95% CI, 0.03–1.3 in cattle, camels, and goats, respectively. Prevalence of avian mycobacterium purified protein derivative PPD reactors in cattle, camels, and goats was 0.7% 95% CI, 0.2–2.0%, 10.0% 95% CI, 7.0–14.0%, and 1.9 95% CI, 0.9–4.0%, respectively, whereby camels had an odds ratio of 16.5 95% CI, 5.0–55.0 when compared to cattle. There was no significant difference between livestock species in BTB positivity. In the present study, the prevalence of bovine tuberculosis was low in Somali pastoral livestock in general and in camels and goats in particular. The high proportion of camel reactors to avian PPD needs further investigation of its impact on camel production.
