Currently, several mite growth culture media used in the production of allergenic extracts contain animal-derived components that limit their use diagnostic and/or therapeutic applications. The aim this study was to evaluate D. pteronyssinus and farinae mites a semi-synthetic medium without proteins produce highly reproducible for purposes be more consistent with regulations health authorities....

BACKGROUND House dust mites (HDMs) such as Dermatophagoides farinae and D. pteronyssinus represent major causes of perennial allergy. HDM proteomes are currently poorly characterized, with information mostly restricted to allergens. As of today, 33 distinct allergen groups have been identified for these 2 mite species, with groups 1 and 2 established as major allergens. Given the multiplicity o...

An in situ core sampling method was used to obtain absolute population density estimates for the mite, Dermatophagoides pteronyssinus Trouessart (Acari : Pyroglyphidae) in the mattress habitat. At the 95 % fiducial limit the numbers of D. pteronyssinus in the top 1.5 cm of substrata were 8,200-26,800 mites m• Mite densities that were calculated from vacuum samples of the same habitat underestim...
