Abstract:
A Persian cat with the complaint of lustreless dry coat, salt and pepper appearance was brought to the dermatology unit of Madras Veterinary College, Chennai. Microscopical examination of the tape impression and hair coat brushings revealed Lynxacarus radovskyi mites with eggs adhering to the hair shaft. The cat was treated with Ivermectin @ 300 µg/kg body weight subcutaneously once a week for 5 weeks after getting owner's consent. The cat was free from the parasites 5 weeks post treatment. Fomite and close contact might aid the spread of infestation. Isolation coupled with full course of treatment favours complete recovery from the infestation.
Insights
A Persian cat infested with Lynxacarus radovskyi mites, causing a dry coat, was successfully treated with Ivermectin. The cat achieved complete parasite clearance after a five-week treatment regimen.
Area of Science:
- Veterinary Dermatology
- Parasitology
- Feline Medicine
Background:
- Feline dermatological conditions can significantly impact animal well-being.
- Lynxacarus radovskyi is an ectoparasite that affects cats, leading to coat abnormalities.
- Accurate diagnosis and effective treatment are crucial for managing parasitic infestations.
Purpose of the Study:
- To report a case of Lynxacarus radovskyi infestation in a Persian cat.
- To describe the clinical presentation and diagnostic findings.
- To evaluate the efficacy of Ivermectin treatment for this specific mite infestation.
Main Methods:
- Clinical examination of a Persian cat presenting with a lustreless, dry coat.
- Microscopical analysis of tape impressions and hair brushings to identify ectoparasites.
- Treatment administration of Ivermectin at 300 µg/kg subcutaneously weekly for five weeks.
Main Results:
- Microscopy confirmed the presence of Lynxacarus radovskyi mites and eggs on the cat's hair shafts.
- The cat showed complete resolution of parasitic infestation five weeks after the treatment concluded.
- No adverse effects were reported during the treatment period.
Conclusions:
- Ivermectin is an effective treatment for Lynxacarus radovskyi infestations in cats.
- Prompt diagnosis and consistent treatment are essential for successful parasite eradication.
- Preventive measures, including isolation and hygiene, may help control the spread of this mite.
