A Case of Feline Demodicosis Caused by Demodex sp.

Abstract

Scurf, without pruritus, appeared on the body surface, especially the dorsal area, of a 15-month-old castrated Russian blue cat. Examination of feces and skin scrapings revealed two types of Demodex mites. The larger type was 111.6μm in size and had a 49.1μm opisthosoma. The smaller type was 77.4μm with an opisthosoma of 30.9μm. In both types, the opisthosoma end was blunt. Fifty-four days after treatment with Amitraz and Ivermectine, no mites were detectable; and, after 98 days, no scurf had reappeared.
