This study was conducted to adopt a serological test for sheep abscess disease
diagnosis using whole cell or toxoid as an antigen, and serum samples from
naturally or experimentally infected animals. The employed conventional
serological tests included tube agglutination test (TAT), card agglutination test
(CAT), and gel diffusion test (GDT). All tests showed agglutination with positive
sera. A total of 50 sera randomly collected from naturally infected sheep was
tested, 41 were found positive. TAT was chosen to monitor the immune response
of the disease. CAT was chosen as test of choice.
