PHAGOCYTOSIS OF CERTAIN MASTITIS BACTERIA IN COLD MILK1

Abstract

There was a highly significant decrease in viable bacteria due to storage for 24 hr. at 40 F of milk containing from 6.5-16 million leukocytes/ml, but no significant change due to continued storage to 72 hr. The difference in susceptibility to phagocytosis was not significant for the organisms showing the greatest and the least decreases in count after 24-hr. storage.
