Abstract

The authors describe the histopathological features of dermatomycosis and sarcoptic mange mixed infection accompanied with chronic granulomatous hidradenitis in five camel's skin samples collected from Al-Najaf slaughter house in Republic of Iraq. Direct examination of the skin scraping with 10% KOH revealed fungal organisms (mycelia and arthrospores) and mites which were consistent with Sarcoptic spp (Sarcoptes scabiei var cameli) in the macerated debris. Histological examination of the skin sections revealed dermatitis characterised by acanthosis with marked parakeratosis, hyperkeratosis and crust formation, rete-pegs, hyperplastic changes in sebaceous glands and hair follicles cells, granulomatous hidradenitis and infiltration with eosinophils, lymphocytes, macrophages and neutrophils. Sections stained with periodic acid-Schiff (PAS) and Gomori's Methenamine silver (GMS) stain, revealed large numbers of fungal arthrospores and hyphae coloured bright magenta with PAS and black with GMS. In conclusion, this study reported mite infestation that occurs concurrently with dermatomycosis accompanied with granulomatous hidradenitis in a species belonging to the Camelidae. Additional studies including better understanding of pathogenesis of mixed infection and its effects on the skin immunity will be desirable for further understanding of those skin diseases in camels.
