Cheyletiellosis in long-haired cats
Abstract:
Among 41 catteries, the majority of which were investigated because of problems of chronic pruritus, 27 proved to be infected by Cheyletiella mites. The skin lesions consisted of small erythematous papules with crusts and some loose hairs. After removal of the loose hairs Cheyletiella mites could be collected with adhesive tape for microscopic examination. Human involvement (papular urticaria) was observed in 20% of the cases. Bathing with Lindane was an effective mode of treatment.
Insights
Cheyletiella mites commonly infest catteries, causing pruritus and skin lesions in cats. This mite infestation can also affect humans, but bathing with Lindane effectively treats the condition.
Area of Science:
- Veterinary Dermatology
- Parasitology
Background:
- Chronic pruritus is a common issue in catteries.
- Cheyletiella mites are known ectoparasites that affect domestic animals.
Purpose of the Study:
- To investigate the prevalence of Cheyletiella mite infestations in catteries experiencing pruritus.
- To describe the clinical signs and transmission to humans.
- To evaluate treatment efficacy.
Main Methods:
- Survey of 41 catteries with a focus on chronic pruritus.
- Diagnosis of Cheyletiella mites via adhesive tape microscopy.
- Clinical observation of skin lesions and human papular urticaria.
- Treatment assessment using Lindane baths.
Main Results:
- 27 out of 41 catteries (65.9%) were infected with Cheyletiella mites.
- Skin lesions included erythematous papules, crusts, and hair loss.
- Human papular urticaria was observed in 20% of cases.
- Lindane bathing proved effective for treatment.
Conclusions:
- Cheyletiella mite infestation is a significant cause of pruritus in catteries.
- The mites pose a zoonotic risk, causing papular urticaria in humans.
- Topical Lindane is an effective treatment for Cheyletiella mites in cats.
