An investigation was carried out to study the pathological changes in canine skin due to demodicosis. The predominant changes included folliculitis, perifolliculitis, furunculosis, acanthosis and hyperkeratosis, parakeratosis and hyperplasia of superficial epidermis. The cut sections of mites were seen in hair follicles, stratum corneum, sweat glands, sebaceous glands as well as in the dermis and epidermis with mild to heavy mononuclear cell reactions. There was ulceration of the epidermis in the severe pustular lesions. | Int.J.Curr.Microbiol.App.Sci 2019 8 3 2176-2179 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 03 2019 Journal homepage http www.ijcmas.com Original Research Article https doi.org 10.20546 ijcmas.2019.803.260 Histopathological Changes in Canine Demodicosis Moneesh Thakur1 Hriyadesh Prasad1 R.S.
