Brucellosis of camels in Kuwait.
This study investigated the presence of Brucella antibodies in serum and milk obtained from camels in Kuwait. Brucella strains were also isolated from the foetus using standard technique (Webridge Lab Techniques). Three serological tests for serum were adopted. These tests were Rose Bengal Plate Test (RBPT), the Serum Tube Agglutination Test (SAT) and the Complement Fixation Test (CFT). The RBPT was used for all sera samples, and both SAT and CET were used for the positive RBPT. Camels that showed a titer of 1:40 in SAT or 1:5 in CFT or greater were considered positive. Thirteen of the samples examined were found positive by CFT (at 1:5); by SAT, they showed a titer of 1:20. One serological test, the Milk Ring Test (MRT), was used for milk. Here 3 and 2 were considered positive reactors but 1+ was considered suspicious. We were unable to isolate the Brucella organism from Sedemine and Cream of milk, but we isolated them from Foetus Brucella abortus and it is confirmed by Webridge Laboratory, U.K. It is Brucella abortus (Biovar 1). The prevalence rate was 14.8% from serum by the CFT and RBPT methods and 10.8% by the SAT method. For milk, the prevalence rate was 8.0%. Two Brucella abortus were isolated from 5 foetuses.
