Solution
The correct option is A The presence of agglutinating antibody in dairy cattle
Milk ring test also called Brucellosis Ring Test (BRT) is conducted in dairies. A suspension of killed Brucella pathogen with haematoxylin is added to the milk sample and kept in a water bath. If the animal is infected with Brucellosis, the milk sample will contain antibodies. Hence the test will be positive and a bluish ring is formed at the cream line as the cream rises. If antibodies are absent no coloured ring is formed, and the milk remains uniformly blue.Thus the correct answer is option A.
