Chronic cholera-like lesions caused by Moraxella osloensis
Abstract:
Cholera-like lesions appeared in four house-confined flocks of tom turkeys on one farm from October 30, 1980, to December 2, 1980; Moraxella osloensis was isolated from the tissues. All flocks were treated with 0.04% sulfaquinoxaline in the water for 3 days. The flocks returned to normal and had normal condemnation rates at slaughter. An experiment was conducted in which six hen turkeys were inoculated with a M. osloensis isolate. The same gross lesions were produced as seen in the field cases.
Insights
Moraxella osloensis caused cholera-like lesions in tom turkeys. Treatment with sulfaquinoxaline resolved the condition, and experimental inoculation reproduced the lesions, confirming M. osloensis as the causative agent.
Area of Science:
- Veterinary Pathology
- Avian Medicine
- Microbiology
Background:
- Outbreaks of cholera-like lesions were observed in domestic turkey flocks.
- Moraxella osloensis was identified as a potential causative agent in affected turkeys.
Purpose of the Study:
- To investigate the etiology of cholera-like lesions in turkeys.
- To confirm the role of Moraxella osloensis in disease development.
Main Methods:
- Isolation and identification of Moraxella osloensis from affected turkey tissues.
- Clinical observation of naturally infected flocks.
- Experimental inoculation of hen turkeys with Moraxella osloensis isolates.
Main Results:
- Moraxella osloensis was consistently isolated from turkeys exhibiting cholera-like lesions.
- Affected turkey flocks treated with sulfaquinoxaline showed clinical recovery.
- Experimental inoculation of turkeys with M. osloensis successfully reproduced the observed gross lesions.
Conclusions:
- Moraxella osloensis is identified as the causative agent of cholera-like lesions in turkeys.
- Sulfaquinoxaline treatment is effective in managing M. osloensis infections in turkeys.
- Experimental models confirm the pathogenicity of M. osloensis in avian species.
