| MYCOBACTERIUM AVIUM SUBSP PARATUBERCULOSIS, JOHNE'S DISEASE, IN CATTLE | |
| Description | MYCOBACTERIUM AVIUM subspecies PARATUBERCULOSIS causes infectious chronic granulomatous enteritis in cattle. Calves are most susceptible to infection from birth to a few months of age but the incubation period prior to the onset of clinical signs generally ranges from 2 to 10 years. Affected cattle continue to eat even as chronic diarrhea and weight loss persist. Fecal-oral transmission from cows to calves is believed to be the most common method of spread; also shed in milk and colostrum. Intrauterine infection can occur but does not appear to be of major importance in the transmission of paratuberculosis. |
