ABSTRACT

Brucellosis is responsible for massive economic losses around the word due to losses of meat and milk (according to abortion, stillbirth, weak of spring and prolonging calving period). The study was conducted at Algetaina Locality of White Nile State of Sudan, during the period of six months of the year 2018. The study was aiming at detection of bovine brucellosis in different dairy farms within the Locality. A total of 100 blood samples and 100 milk samples were collected from the same lactating cows. Sera were separated from blood samples and subjected using Rose Bengal Plate Test (RBPT) and modified Rose Bengal Plate Test (mRBPT 1:2) for detection of Brucella antibodies. Milk samples were examined using Milk Ring Test (MRT)for detection of Brucella antibodies. According to questionnaire survey of dairy farms in Algetaina locality there were no records about brucellosis in the locality, but there were records about stillbirth 5 (45.5 %) and cases of retained placenta 8 (72.2 %). Six (6%) serum samples gave positive results with RBPT and 12 (12%) were positive for mRBPT 1:2. Only 2 (2%) milk samples gave positive reaction with MRT. From this study we conclude that mRBPT is more specific and sensitive than RBPT and MRT in detecting Brucella antibodies.
