Contagious ecthyma in lambs and laboratory personnel
Laboratory Animal Science
|October 1, 1983
Summary
Contagious ecthyma (orf virus) can transmit from lambs to humans through direct contact with infected secretions. Zoonotic disease prevention guidelines are crucial for healthcare workers handling infected animals.
Area of Science:
- Veterinary Medicine
- Infectious Diseases
- Public Health
Background:
- Contagious ecthyma is a viral skin disease common in sheep and goats.
- Zoonotic diseases pose risks to humans, especially those in close contact with animals.
Observation:
- Three lambs diagnosed with contagious ecthyma were studied.
- Two researchers contracted the disease after direct contact with oral secretions from infected lambs.
- Electron microscopy confirmed viral particles in a lamb's gingival biopsy.
Findings:
- Direct transmission of contagious ecthyma from lambs to humans occurred.
- Contaminated gavage feeding tubes likely facilitated lamb-to-lamb transmission.
- The study highlights the potential for zoonotic transmission of orf virus.
Implications:
- The findings underscore the importance of biosafety measures in veterinary settings.
- Development of safety guidelines is essential to prevent zoonotic disease transmission, including orf virus and Q fever.
- Protecting healthcare workers and the public from zoonotic pathogens is a priority.
