Serological screening of Coxiella burnetii (Q fever) and Brucella spp. in sheep flocks in the northern prefectures of Japan in 2007
Ovine sera collected from the northern Prefectures of Hokkaido, Iwate and Aomori in Japan, were examined for the presence of antibodies against Coxiella burnetii (Q fever) using the complement fixation test and, against Brucella spp., using both the rapid serum agglutination test and the complement...
