Microscopic dust mites are found everywhere in the houses - in mattresses, Carpets, cushions, clothing, furniture, book shelves etc.
Dermatophagoides pteronyssinus and D. farinae are the most predominant species.
Dermatophagoides means skin eaters.
Faecal material from the mites and also their decomposing moulted skins provide an allergic response.
185 million adults worldwide suffer from dust mite allergies, Hay Fever, Eczema and asthma (increasing at 5% p.a.)
Exposure to dust allergens in childhood increases chances of adulthood asthma.
The wheeze-inducing proteins are digestive juices from the mite gut which are quite potent. The proteolytic activity of Der p I, the group I allergen of Dermatophagoides pteronyssinus, may influence the allergenicity of mites.
