Summary
Acarid mites (Psorergates cercopitheci) infested vervet monkeys, causing skin lesions around the eyes. Topical treatments proved effective in eradicating the mite infestation in most cases.
Area of Science:
- Veterinary Dermatology
- Parasitology
- Primate Health
Background:
- Acariasis, a skin infestation by mites, can affect various animal species.
- Understanding mite prevalence and host-parasite interactions is crucial for wildlife health management.
Observation:
- Seven cases of acariasis were identified in a colony of vervet monkeys (Cercopithecus pygerythrus).
- Lesions were localized to the eyelids (palpebrae) and the areas surrounding the eyes (periorbital).
Findings:
- The causative mite was identified as Psorergates cercopitheci through skin scrapings and biopsies.
- Biopsies revealed that the parasite invaded only the superficial epidermis.
- Skin scrapings from other body areas of infested monkeys did not yield mites.
- Despite physical contact with conspecifics, most other monkeys remained uninfested, suggesting limited transmission or specific host susceptibility.
Implications:
- This study highlights Psorergates cercopitheci as a potential pathogen in vervet monkeys, affecting facial skin.
- The superficial epidermal invasion and localized lesions suggest a specific host-parasite relationship.
- The effectiveness of topical treatments indicates a viable therapeutic strategy for managing acariasis in this primate species.
- Further research could explore transmission dynamics and host resistance factors in Psorergates cercopitheci infestations.
