Abstract
Thirty-four cultures recovered from material of bovine origin in England, Scotland and Wales were identified unequivocally as Brucella abortus strain 19 (S19). All had the properties of carbon dioxide-independent B abortus biotype 1 strains, were inhibited by penicillin G and thionin blue at standard concentrations and behaved in oxidative metabolism and guinea pig virulence tests as typical S19. Their sensitivity to i-erythritol varied somewhat between cultures as did reference subcultures of S19. Of the total number of isolates, 11 were recovered from abortion material or cyetic products, 10 were from calves which died from a hypersensitivity reaction within 24 hours of S19 vaccination and the remainder were from milk or internal organs. From the evidence available, there is little to suggest that calfhood vaccination with S19 has resulted in persistent systemic infection in other than a very small proportion of the animals inoculated.
