JPG, Corynebacterium bovis: A Practical Summary for Controlling Mastitis

This publication is available in a PDF file format only.

Corynebacterium bovis is a contagious, Gram-positive mastitis-causing pathogen. C. bovis will typically produce little to no growth on blood agar after 24
hours of culture, but it will show creamy, gray, or white nonhemolytic colonies at 48 hours. C. bovis is mildly pathogenic and will usually cause only a mild
increase in somatic cell count and a slight reduction in milk production. Information in this publication
was summarized from the National Mastitis Council’s Laboratory Handbook on Bovine Mastitis (Hogan et al. 1999).
