Summary
Fowl cholera outbreaks caused severe eye infections like blepharoconjunctivitis and hypopyon in turkeys. Experimental Pasteurella multocida exposure confirmed these ocular lesions, including panophthalmitis.
Area of Science:
- Veterinary Ophthalmology
- Avian Pathology
Background:
- Fowl cholera, caused by Pasteurella multocida, is a significant disease in domestic poultry.
- Ocular manifestations of fowl cholera are not well-documented, particularly in turkeys.
Purpose of the Study:
- To investigate and describe the ocular lesions associated with fowl cholera in turkeys.
- To identify the causative agent, Pasteurella multocida, in affected ocular tissues.
Main Methods:
- Observation of clinical cases during two natural fowl cholera epornitics in turkeys.
- Experimental inoculation of turkeys with Pasteurella multocida via drinking water.
- Isolation and identification of P. multocida from ocular lesions.
Main Results:
- Blepharoconjunctivitis and hypopyon were consistently observed during natural outbreaks.
- Experimental exposure resulted in sporadic blepharoconjunctivitis, hypopyon, anterior synechiae, and panophthalmitis.
- Pasteurella multocida was successfully isolated from the observed ocular lesions.
Conclusions:
- Pasteurella multocida can cause significant ocular pathology in turkeys, including severe conditions like panophthalmitis.
- Blepharoconjunctivitis and hypopyon are key clinical signs of fowl cholera affecting turkey eyes.
- Understanding these ocular manifestations is crucial for diagnosing and managing fowl cholera in poultry.
