SENSITIZATION TO THE HOUSE-DUST MITE, DERMATOPHAGOIDES-FARINAE, IN DOGS WITH SARCOPTIC MANGE

Sensitisation to the house dust mite, Dermatophagoides farinae, was de monstrated by skin testing and allergen-specific IgG determination in 15 out of 20 dogs in which a definitive diagnosis of sarcoptic mange w as made following recovery of Sarcoptes scabiei mites on skin scraping s. After therapy, no dogs exhibited clinical signs of atopic dermatiti s. Intradermal skin testing and 40 per cent of specific IgG assays for Dermatophagoides farinae were negative 90-180 days after the original diagnosis.
