Lepidoglyphus destructor extract
Freeze-dried extract of Lepidoglyphus destructor whole culture.
Lepidoglyphus destructor, also known as storage mite, belongs to the Acaridae family. In Europe, Lepidoglyphus destructor has been reported to be a major source of mite allergy in rural and urban environments. Our Lepidoglyphus destructor extract is delivered in freeze-dried form and available from stock. This mite is usually found in places where animal and plant food are produced and the humidity is very high. Therefore, it doesn’t come as a surprise that Lepidoglyphus destructor is generally stored in hay and frequently causes respiratory allergies among farm workers. Moreover, it is present in 21-38% of the commercially purchased cereal based foods.
These mites feed on variety of protein – rich compounds, above all on plants and microorganisms. Furthermore they grow at a relative air humidity of 65 – 100%, prefer light environment and temperatures between 20 – 30°C.
A number of allergenic proteins have been isolated from Lepidoglyphus destructor. 90% of patients are allergic to Lep d 2, which has its two variants Lep d 2.0101 and Lep d 2.0201. It has been pointed out that Lep d 5, Lep d 7 and Lep d 13 respectively bind to 9%, 62% and 13% sera from L. destructor sensitised subjects.
