title: A non-hemolytic, group B Streptococcus infection of cultured bullfrogs, Rana catesbeiana, in Brazil.
abstract: A systemic streptococcal infection in cultured bullfrogs in Brazil was characterized by necrotizing splenitis and hepatitis with hepatic and renal hemorrhage. A non-hemolytic Group B Streptococcus appeared to be the cause of the lesions, and the stimulus for the splenic reticuloendothelial hyperplasia observed in the animals. Stress may have been a factor in the development of the pathological condition.
