Small volumes of milk containing on average less than 10 colony-forming units of Staph. aureus were injected into the teat cisterns of 39 quarters of 10 cows. Typical staphylococci were recovered from 14 quarters after overnight incubation of milk stripped manually from each quarter 10 min. after injection. There was an inverse relationship between the total leukocyte count of the milk taken from the quarter before infusion and recovery of staphylococci.
