“…This cross-allergenicity was further supported by Voorhost et al, 6 ; Pepys et al, 7 ; Frankland et al, 8 and Billioti et al, 9 In contrast, Kawai et al 10 and Stenius and Wide 11 contested the above conclusions on the grounds that there was no significant correlation between reactions to house dust extract and mite extract. Other determinants were suggested for this non-interaction and included cotton linters, 12 human dander, animal epithelium and a variety of miscellaneous substances. 13 In an excellent review by Maunsell et al, 14 the mite was found in highest numbers on the bedding, slightly lower on the bedroom floors and in lowest numbers on the living room floor.…”
