Summary
Dictyocaulus arnfieldi lungworm was found in donkeys at a zoological garden. Biological data on its development stages were recorded, with larval development taking 84 hours.
Area of Science:
- Veterinary Parasitology
- Zoological Wildlife Health
- Donkey Respiratory Diseases
Background:
- Donkeys in zoological gardens can be susceptible to parasitic infections.
- Lungworm infections pose a significant health risk to equid populations.
- Postmortem examinations are crucial for identifying endemic pathogens.
Purpose of the Study:
- To identify and document Dictyocaulus arnfieldi in donkeys at Kafr El-Sheikh Zoological Garden.
- To record and analyze the biological data of Dictyocaulus arnfieldi developmental stages.
- To contribute to the understanding of parasitic diseases in captive equid populations.
Main Methods:
- Postmortem examination of 54 adult donkeys.
- Identification of Dictyocaulus arnfieldi in lung tissues.
- Recording of biological data for parasite maturation, hatching, and larval development.
Main Results:
- Dictyocaulus arnfieldi was confirmed in the lungs of slaughtered donkeys.
- The maturation, hatching, and development of 2nd and 3rd stage larvae required 84 hours.
- Biological data for various developmental stages were collected and analyzed.
Conclusions:
- Dictyocaulus arnfieldi is a prevalent lungworm affecting donkeys in this zoological setting.
- Understanding the parasite's life cycle is vital for disease management strategies.
- Findings highlight the importance of monitoring parasitic infections in captive wildlife.
