Summary
Severe dermal necrosis in turkeys was linked to Pasteurella multocida Serotype 1. Mouse bites likely introduced the bacteria, causing significant skin lesions and carcass condemnation in a commercial flock.
Area of Science:
- Veterinary Pathology
- Bacteriology
- Poultry Science
Background:
- Poultry farming faces economic losses due to disease outbreaks.
- Pasteurella multocida is a significant pathogen in avian species.
Observation:
- Severe dermal necrosis was observed in turkeys from a commercial flock.
- Affected birds included live turkeys and condemned carcasses at a processing plant.
Findings:
- Pasteurella multocida Serotype 1 was identified as the causative agent.
- Experimental inoculation confirmed P. multocida Serotype 1's ability to induce progressive dermal necrosis in turkeys.
- The bacteria were successfully reisolated from induced dermal lesions.
- Mouse infestation in turkey houses was noted, suggesting a potential vector for skin injury and infection.
Implications:
- Mouse bites may serve as a primary route for P. multocida infection in turkeys.
- Understanding transmission routes is crucial for preventing future outbreaks.
- Implementing biosecurity measures to control rodent populations can mitigate risks associated with P. multocida dermal necrosis.
