Biotypes, serotypes and phage types of caprine strains of Staphylococcus aureus

Summary Nine of 11 caprine strains of Staphylococcus aureus examined belong to biotype C. They were typable serologically using antisera developed for typing human strains of Staphylococcus aureus . H 2 was found to be the dominant thermostable antigen whilst 1 and 0 were the most common thermolabile antigens. Some strains possessed protein A and poly A β ( β -glucosaminyl ribitol teichoic acid). Phage typing of the strains was achieved with an international set of phages for typing human strains of Staphylococcus aureus and they belong to phage groups II, and the mixed group.
