Investigating selective media for optimal isolation of Brucella spp. in South Africa

Onderstepoort Journal of Veterinary Research, 2020
Bovine brucellosis in South Africa is caused mainly by Brucella abortus biovar (bv.) 1 and less frequently by B. abortus bv. 2. Bacterial isolation is regarded as the gold standard for diagnosis of Brucella species; however, it is not very sensitive. The
