Corynebacterium ulcerans infection associated with untreated milk

Infection with Corynebacterium ulcerans has been previously reported in association with cows' milk. Further evidence that the disease is a zoonosis is given in this report of infection in a consumer of untreated milk. The organism was isolated from a sample of milk, and from two cows in a herd of 93 Jersey cattle. One of the farm workers was a symptomless nasal carrier.
