[Comparison, using RAST-inhibition, of the allergenic potency of Dermatophagoides pteronyssinus extracts obtained from: whole mite culture, fraction of enriched mite culture, fraction of feces enriched culture, purified mite bodies, commercial extracts].

The RAST-inhibition potency has been obtained from five extracts prepared by: whole mite culture, mites-enriched culture, faeces-enriched culture, purified mite bodies, commercial extract. The present study demonstrates that extracts of: a) purified bodies, and b) faeces-enriched culture are both potent preparations in RAST-inhibition.
