title: Effect of damage to the teat end on the experimental induction of mastitis in dry cows with Corynebacterium pyogenes.
abstract: The teat ends of 12 dry cows were contaminated with Corynebacterium pyogenes. To determine whether a pre-existing (an)aerobic bacterial infection of the udder was a predisposing factor for a C pyogenes mastitis they included infected and uninfected quarters. Anaerobic bacteria could not be found and mastitis was not induced. When the teats were contaminated with C pyogenes after the teat ends had been injured 30 of the quarters became infected, and anaerobic bacteria were demonstrated in many quarters.
