Euroglyphus maynei
Summary
Euroglyphus maynei is one of the Pyroglyphinae family of dust mites, known commonly as Mayne's house dust mite. E. maynei thrives in humid conditions within the home, notably in bedding, carpets and furniture and is found in dust in around 30–40% of homes. Sensitization to house dust mites (HDMs) represents a major cause of respiratory allergy worldwide in children, adolescents, and adults.
Epidemiology
Worldwide distribution
Approximately 20% of the population in industrialized countries are sensitized to HDM allergens.
Route Of Exposure
Main
Inhalation.
Secondary
Ingestion and contact.
Clinical Relevance
Mites are the sources of potent allergens that sensitize and induce IgE-mediated allergic reactions. HDMs are a major cause of atopic sensitization with symptoms induced by direct contact (conjunctivitis, eczema), inhalation (rhinitis, asthma, eczema), and ingestion (urticaria, anaphylaxis).
Sensitization to house dust mites (HDMs) is a major cause of respiratory allergy worldwide in children, adolescents, and adults.
Prevention And Therapy
Prevention strategies
Several dust mite avoidance measures have been proposed, including mattress and pillow encasings, high efficiency particulate air filtration vacuum cleaners, air purification, acaricides, humidity control, and physical removal of mite reservoirs. The most common strategies that have been used to control domestic allergen exposure are physical barriers such as covers for pillows, duvet, and mattresses.
Cross-Reactivity
E. maynei produces an allergen that cross reacts with Der P1 and shows some cross-reactivity with Dermatophagoides pteronyssinus and Dermatophagoides farinae. Antigens from E. maynei are also cross-reactive with some antigens from the ectoparasitic scabies mite, Sarcoptes scabiei. Cross-reactivity due to tropomyosin and haemocyanin among shrimp, cockroach, and house dust has been suggested.
