Comparison of standard tube and microagglutination techniques for determining brucella abortus antibodies

ABSTRACT

A microagglutination method for determining the agglutinating and blocking antibodies to Brucella abortus is described. A collection of sera from cattle in 2 rural areas of Saudi Arabia were tested by the microagglutination methods and the standard methods in tube. The results were compared and showed that where discrepancies occurred, these were due to the microagglutination methods being more sensitive. It is concluded that these are suitable methods for screening animal stocks
