Abstract:
One of the more important etiological factors of allergies are mites occuring in the closest vicinity of humans, i.e. in the house dust and in the stored foodstuffs. The most important are the species representing the families: Pyroglyphidae (mainly Dermatophagoides pteronyssinus, D. farinae, and Euroglyphus maynei), Glycyphagidae (e.g. Lepidoglyphus destructor, Blomia sp.), and Acaridae (e.g. Tyrophagus putrescentiae, Acarus siro). Mites shed an abundance of allergenic proteins. Particularly abundant in allergens are the extracts of mite faeces as well as the extracts of their purified bodies or culture substrate. In humans the may inflict atopic allergies (respiratory and dermal), such as bronchial asthma, rhinitis, or atopic eczema. It has been estimated that some 5% of the human population is sensitive to dust mites allergens.
Insights
House dust mites are a major cause of allergies, triggering conditions like asthma and eczema in 5% of the population. Allergenic proteins from mite bodies and feces are key culprits.
Area of Science:
- Allergen research
- Immunology
- Environmental health
Context:
- Mites, particularly house dust mites, are significant etiological factors in human allergies.
- Common allergenic mite species include Dermatophagoides pteronyssinus, Dermatophagoides farinae, and Acarus siro.
- Allergens are found in mite feces, bodies, and culture substrates.
Purpose:
- To identify and characterize the role of mites as allergens in human health.
- To understand the sources and types of mite-derived allergens.
- To inform strategies for allergy prevention and management.
Summary:
- Mites in house dust and stored food are primary allergy triggers.
- Key mite families involved are Pyroglyphidae, Glycyphagidae, and Acaridae.
- Exposure to mite allergens can lead to atopic allergies like asthma, rhinitis, and eczema.
Impact:
- Approximately 5% of the human population exhibits sensitivity to dust mite allergens.
- Highlights the importance of controlling mite populations in living environments.
- Provides foundational knowledge for developing targeted allergy therapies and diagnostics.

Asthma I: Introduction
Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
