A review of camel brucellosis

We reviewed the literature on camel brucellosis. The seroprevalence of brucellosis in camels appears to follow two distinct patterns: a low (2-5%) prevalence in nomadic or extensively kept camels and a high (8-15%) prevalence in camels kept intensively or semi-intensively. The infection is caused by different biotypes of Brucella abortus and Brucella melitensis. Many gaps exist in the literature on the epidemiology of camel brucellosis. There is no clear policy in any of the camel-keeping countries regarding the control of brucellosis in camels. We suggest whole-herd vaccination in low-prevalence countries and test-and-slaughter followed by vaccination in high-prevalence countries.
