House dust mite, Dermatophagoides pteronyssinus, and its allergens: effects of washing



House dust mite, Dermatophagoides pteronyssinus, and its allergens: effects of washing



Allergy 44(6): 396-400



The study was undertaken to evaluate the effect washing at various temperatures would have on the house dust mite, Dermatophagoides pteronyssinus, and its allergens. Young and old mite cultures underwent a simulated washing programme. To record the number of live mites prior to and after washing a new counting method was applied. The findings demonstrated that although washing reduced the number of live mites, a washing programme at minimum temperature 58.degree. C was required in order to achieve complete extermination of the house dust mites. A distinct protein loss was observed when washing at higher temperature, thus further reducing the total allergen pool without loss of allergen activity as determined by direct RAST.
