Summary
This study found that Baylisascaris potosis roundworm larvae can migrate in chicken tissues for up to 30 days, suggesting chickens may act as paratenic hosts and posing a potential foodborne risk to humans.
Area of Science:
- Veterinary Parasitology
- Zoonotic Disease Research
- Foodborne Pathogen Studies
Background:
- Baylisascaris larvae cause larva migrans in various hosts.
- Baylisascaris potosis is the roundworm of kinkajous (Potos flavus).
- Understanding avian paratenic hosts is crucial for parasite control.
Purpose of the Study:
- To investigate the larval migration of Baylisascaris potosis in chickens.
- To identify clinical manifestations associated with B. potosis infection in chickens.
- To assess the potential of chickens as paratenic hosts for B. potosis.
Main Methods:
- Oral inoculation of 3-week-old chickens with 3,000 B. potosis eggs per chick.
- Necropsy of chickens at 1, 2, 3, 7, 30, and 90 days post-inoculation.
- Larval counts in various organs and tissues.
Main Results:
- Larvae were detected in the liver, lungs, and breast muscles of 36.1% of chickens up to 30 days post-inoculation.
- No clinical signs of infection were observed in the chickens.
- Larval migration was confirmed in chicken tissues, with peak presence at 3 days post-inoculation.
Conclusions:
- Chickens can serve as paratenic hosts for Baylisascaris potosis.
- B. potosis larvae can migrate and survive in chicken tissues for at least 30 days.
- B. potosis infection in chickens represents a potential foodborne disease risk for humans.
