Abstract

Extracts of Lepidoglyphus destructor were examined for the presence of digestive enzymes known to be allergenic in the pyroglyphid mites, such as Dermatophagoides pteronyssinus and D. farinae, with particular emphasis on the proteases and carbohydrases. Three serine proteases and one cysteine protease were detected, each with an apparent molecularweight of 25 K as judged by gel filtration. The serine proteases appeared to correspond to the trypsin, chymotrypsin and collagenolytic enzymes previously demonstrated in mites belonging to the genus Dermatophagoides. Chromatofocusing studies showed that each of the serine proteases was polymorphic. Extracts of L. destructor were also found to contain amylase, glucoamylase and an enzyme(s) that lysed Gram-positive bacteria, such as Micrococcus lysodeikticus and Bacillus megatarium. These data indicate that extracts of L. destructor contain a spectrum ofdigestive enzymes similar to that shown to be present in the Pyroglyphid mites. The allergenicity of such enzymes in L. destructor remains to be determined. (C) 1998 Elsevier Science Inc.
