The Strep. Agalactiae Herd

An Alternate Approach

Abstract

Strep. agalactiae as the causative agent in problem mastitis, elevated somatic cell count (SCC), and/or high tank standard plate count (SPC) herds has been around for some time. It is not as new and exotic as are some of the more recently identified pathogens, yet it remains a significant contributor to the number of problem mastitis herds throughout the country, despite its relative ease of control. Therefore, it is important that we not bypass Strep. Ag. in a discussion of Quality Milk Production.

This case is typical of the way a Strep. ag. problem herd has presented itself during my clinical experience.
