EXTRACELLULAR PRODUCTS OF THE MASTITIS-INDUCING PATHOGENS, ESCHERICHIA COLI (EC) AND STAPHYLOCOCCUS AUREUS (SA), ACTIVATE BOVINE MILK KALLIKREINS.

A conference paper on the role of extracellular products of the mastitis-inducing pathogens, Escherichia coli (EC), and Staphylococcus aureus (SA) in the activation of bovine milk kallikreins is presented. The study indicated that the presence in milk of the pathogens is associated with elevated bradykinin (BK) levels. It showed that both EC and SA directly activate BK formation in milk by activating synthetic tissue- and plasma-kallikreins-like activity in the milk.
