[An outbreak of Klebsiella pneumoniae mastitis].

A serious outbreak of mastitis caused by Klebsiella pneumoniae is described. Shortly after drying off, three cows died of mastitis caused by Klebsiella pneumoniae and five other cows became seriously ill but survived. Sawdust contiminated with Klebsiella pneumoniae was identified as the most likely source of these infections. In addition to detection of possible sources of infection, another important aspect of eradication is the detection of quarters infected with Klebsiella pneumoniae. Rigorous application of these measures led to resolution of the outbreak within a few months.
