House dust mite excrements and allergy

House dust mites are a major source of allergens and a major contributor to allergic diseases such as asthma, rhinitis, and atopic dermatitis. House dust mite excrements are considered the main source of allergy (1). The house dust mite excrements are pellets with a diameter of about 10–40 µm. These pellets dry up, decompose into fine dust, float into the air and are inhaled. The small size of the excrements can cause problems for people who are sensitive to house dust mites because the smaller the faecal particle carrying active enzymes, the deeper it can travel into the lungs, even reaching delicate areas of gas exchange.

We can deliver excrements from the house dust mites D. pteronyssinus and Dermatophagoides farinae in vials of 1 mg. These mite products are analysed for cysteine and serine protease and will be delivered with a certificate of analysis. Please contact us for more information and pricing.
