By means of type differentiation of the serological B group streptococci isolated from the cow mammary glands the following type antigens could be found: Ia 8X, Ib 4X, II 40X, III 16X, R 4X, X 80X. In 54% of the cultures examined several antigenic types were concurrently found. In one mammary gland several antigenic differentiation; epizootological investigation; cross reactions impedes the utilization of type differentiation of the serological B group streptococci for epizootological investigation. The individual antigenic types of the serological B group streptococci can partially be separated by the examination of isolate colonies.
