Experimental production of bovine mastitis with streptococci and other bacteria

Abstract

Certain aspects of the etiology of bovine mastitis have been studied but the majority of workers have dealt with organisms from milk from infected udders. The bacteria isolated have fallen, for the most part, into two groups, hemolytic and nonhemolytic streptococci. A smaller percentage is due to the staphylococci, B. pyogenes and members of the colon-aerogenes group. In the literature are few references to the experimental production of mastitis. This is due, in all probability, to the fact that the experiment is an expensive procedure because one cannot carry it on without a possibility of damaging the value of the animal.
