Bacteriological and serological study on brucellosis infection in camel (Camelus dromedaries), Al-Hodeida governorate, Yemen

Camels are highly susceptible to brucellosis caused by Brucella melitensis and Brucella abortus however, diagnosis of camel brucellosis is difficult because most camels appear normally and there are no clear clinical signs on affected camels. Study of camel brucellosis especially on Al-Hodeida governorate and the association of Brucella spp. with abortion cases in camel’s population are very limited. Total 295 samples were collected from 100 camels and 195 samples were subjected for isolation other 100 serum samples were examined by Rose Bengal Plate Test (RBPT), febrile agglutination tests to determine prevalence of brucellosis. Result recoded high prevalence of brucellosis in camels by using RBPT, culture of vaginal swabs, Milk ring test (MRT) and culture of whole blood sample with prevalence 0.11, 0.10, 0.05 and 0.02 respectively. Eight camel’s abortion cases have been recorded in current study and it were positively associated with Brucella spp. Infection. In conclusion, high prevalence of brucellosis needs serious controlling measurement to avoiding economical losses and zoonosis hazard aspect. Both Brucella melitensis and Brucella abortus is a major cause of brucellosis in camels rather than highly association with abortion cases.
