Abstract

453 cattle blood samples were collected from northern Jordan. They were examined for Brucella abortus antibodies by ap < /strong>plication of the tube aglutination test (SAT) and the complement fixation test (CFT). In SAT, 18(4%) samples were seropositive and 43(9.5%) were doubtful, while in CFT 8(1.7%) samples were seropositive. The highest titre recorded in SAT was 1:80 and in CFT was 1:40. The obtained results indicate a 4.6% incidence of brucellosis among cattle. The positive reactors are strong evidences of the presence of a potent focci responsible for spreading the infection among herds in northern Jordan.
