Extract from house dust mite (Dermatophagoides farinae) was treated with glutaraldehyde (GA) and examined for its allergenicity and immunogenicity. The allergenicity of glutaraldehyde-treated mite extract (GA-M) was decreased significantly when compared with untreated mite extract (UN-M) by skin test in mite allergic individuals. Immunogenicity of GA-M was at least similar with that of UN-M, when examined by formation of antibodies to UN-M in guinea pigs. Fractionations of GA-M and UN-M revealed that polymerization occurred and proteins of higher molecular weight increased after the treatment of mite extract with GA. The results suggest potential usefulness of the polymerized mite antigens in immunotherapy.

D008925 Mites Any arthropod of the subclass ACARI except the TICKS. They are minute animals related to the spiders, usually having transparent or semitransparent bodies. They may be parasitic on humans and domestic animals, producing various irritations of the skin (MITE INFESTATIONS). Many mite species are important to human and veterinary medicine as both parasite and vector. Mites also infest plants. Acarus,Mite
