An Unusual Enteritis in Turkeys Jim Hanson Provincial Veterinary Laboratory
A group of 12-week-old heavy turkeys was submitted to the Edmonton Laboratory on October 16, 1993. One percent mortality per day was being experience in this flock of 6,000 birds. There were 24,000 birds on the barn. Birds were on range, with access to floor pens. The birds were dying acutely as evidenced by their body condition at time of post mortem examination. Gross lesions were confined to the large intestine and cecum. Lesions were prominent, distinct ulcers with raised necrotic material elevated above the surrounding intestinal epithelium. Salmonella agona was isolated from the large intestine and cecum. The flock responded well to antibiotic therapy. Subsequent submissions from this flock produced a number of birds with markedly swollen ceca containing caseous necrotic cores. A second flock of birds on the same farm subsequently broke with a similar disease. Salmonella agon (with heavy growth from the lesions) was again isolated. The focal ulcerative lesions with prominent elevated cones of necrotic debris had not been seen in previous intestinal salmonellosis in turkeys at our laboratory.
