|July 1, 1984
Abstract:
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.
Insights
Mycoplasma gallisepticum caused infectious sinusitis in Nigerian turkeys. This diagnosis marks the first reported isolation of the pathogen in turkeys within Nigeria, with low flock mortality observed.
Area of Science:
- Veterinary Microbiology
- Avian Pathology
Background:
- Infectious sinusitis is a significant respiratory disease in poultry.
- Mycoplasma gallisepticum (MG) is a primary causative agent of respiratory disease in turkeys.
- Limited data exists on MG prevalence in Nigerian turkey populations.
Purpose of the Study:
- To identify the causative agent of severe sinusitis in imported broad-breasted white turkeys in Nigeria.
- To report the first isolation and diagnosis of Mycoplasma gallisepticum in turkeys in Nigeria.
Main Methods:
- Clinical examination of affected turkeys.
- Bacteriological culture and isolation of Mycoplasma gallisepticum from respiratory tissues.
- Serological testing to confirm Mycoplasma gallisepticum infection.
Main Results:
- Thirty out of 70 turkeys (42.8%) tested positive for Mycoplasma gallisepticum.
- Both cultural and serological methods confirmed the presence of MG.
- A low flock mortality rate of 5.7% was recorded.
Conclusions:
- Mycoplasma gallisepticum was identified as the cause of infectious sinusitis in the studied turkey flock.
- This study represents the first documented isolation of Mycoplasma gallisepticum in turkeys in Nigeria.
- The findings highlight the need for surveillance and control measures for MG in Nigerian poultry.
