Evidence is presented that nearly all Staphylococcus aureus infections of the bovine mammary gland are by encapsulated organisms (94% of isolates examined). This observation is based on the demonstration of diffuse growth in serum-soft agar, of cultu

Strains of Staphylococcus aureus were isolated from bovine mastitis, subcultured and maintained in the laboratory for up to 3 years. Encapsulation was assessed by production of a diffuse colony in serum-soft agar. Eight (4%) of 200 strains were encap
