Infectious sinusitis in turkeys at Ibadan, Nigeria.

Thirty out of 70 imported broad-breasted white turkeys with severe sinusitis were both culturally and serologically positive for Mycoplasma gallisepticum. Infectious sinusitis due to M. gallisepticum was therefore diagnosed. A low mortality of 5.7% of the total flock was recorded. This appears to be the first published report on M. gallisepticum isolation in turkeys in Nigeria.
