title: Restriction endonuclease analysis of Brucella abortus.
abstract: The restriction endonuclease profiles of bacterial DNA from Brucella abortus isolates were evaluated. It was not possible to distinguish between vaccine strain 19 and virulent (biotype 1 and biotype 2) strains of B abortus. Restriction endonuclease analysis is therefore not a suitable epidemiological tool in bovine brucellosis investigations. The genetic homogeneity of the Brucella genus was reinforced by these findings.
