TL;DR: Examination of skin scrapings from the affected sites revealed different developmental stages of Knemidokoptes mutans and Laminosioptes cysticola mites, which is reported for the first time from India.
Abstract: Birds reared in backyard poultry farming system are more prone to parasitic infestation resulting in economic losses to rural community. The present study reports occurrence of Knemidokoptes mutans and Laminosioptes cysticola mites in a male Aseel bird. Clinical signs observed in the affected bird include hyperkeratosis with whitish film layer on shank and hock region of legs. Focal areas of sloughing of skin with oozing of blood were also observed on the back and on the legs. Examination of skin scrapings from the affected sites revealed different developmental stages of Knemidokoptes mutans and Laminosioptes cysticola mites. This paper reports occurrence of L. cysticola for the first time from India. The bird was treated with ivermectin injection through intramuscular route.
TL;DR: A routine examination of a captive juvenile great-horned owl (Bubo virginianus) revealed bilateral proliferative papillary hyperkeratosis on the feet, the first record of this parasite in a great- horned owl.
Abstract: A routine examination of a captive juvenile great-horned owl (Bubo virginianus) revealed bilateral proliferative papillary hyperkeratosis on the feet. Microscopic examination of skin scrapings produced numerous mites identified as Knemidokoptes mutans. This is the first record of this parasite in a great-horned owl. A single dose of ivermectin (200 μg/kg) was effective in treatment of this infection.
