The interference between coagulase negative staphylococci and Corynebacterium bovis and the common udder pathogens in the lactating cow.

In these experiments it was studied whether the presence of the low pathogenic coagulase negative staphylococci or Corynebacterium bovis in the lactating bovine udder would have a protective effect against some of the common udder pathogens such as Staphylococcus aureus, the streptococci and the Gram negative bacteria.
