Abstract

The incidence of coliform mastitis has been on the increase since a serious effort has been made to eliminate Streptococcus agalactia and Staphylacoccus aureus mammary infections in dairy herds throughout the U.S. As somatic cell counts decrease in dairy cows, they tend to be more susceptible to coliform mastitis. It is likely that this trend will continue as long as stringent controls are being placed on somatic cell levels and premiums are being offered for better quality milk.
