Outbreak of Mycoplasma iowae infection in commercial turkey poults.
In September 1989, 17-day-old turkey poults were submitted to Iowa State University because of leg weakness and dehydration. These birds were commercial large white toms from a flock of 23,214. Lesions observed at necropsy included chondrodystrophy of the hock joints, clear fluid in hock joint spaces, valgus deformities and shortening of the tarsometatarsal bones, and curled toes. Mycoplasma iowae was isolated and identified from swabs of the air sac, cloaca, hock joint, and large intestine. Approximately 1.4% of the flock was culled between 2 and 8 weeks of age because of leg problems. M. iowae infection did not severely affect overall flock performance. Eighty-seven percent of the flock was marketed at 18 weeks of age with an average per turkey weight of 29.5 pounds.
