[Acari of food storage facilities. An ecologic and immuno-allergic study]
Abstract:
The authors studied the commonest species of storage mites, living in granaries and in house dust. They found nine species of mites belonging to different systematic groups and were identified: Acarus siro, Tyrophagus putrescentiae, Glycyphagus domesticus, Lepidoglyphus destructor, Chortoglyphus arcuatus, Androlaelaps casalis, Cheyletus fortis, Cheyletus tenuipilis, Thyreophagus entomophagus. Skin tests were performed on 14 patients with house dust allergy, using extracts of three storage mites, most commonly found in house dust (Acarus siro, Glycyphagus domesticus, Lepidoglyphus destructor) and Euroglyphus maynei, Dermatophagoides pteronyssinus, Dermatophagoides farinae. The results of the skin tests have suggested that sensitization to storage mites may be due a degree of cross-reaction between storage species and the two Dermatophagoides.
Insights
This study identified nine common storage mite species and tested their allergenicity in patients with house dust allergy. Results suggest cross-reactivity between storage mites and Dermatophagoides species, impacting allergy management.
Area of Science:
- Allergenicity and Immunology
- Acarology
- Environmental Health
Context:
- Storage mites are prevalent in granaries and house dust, posing potential health risks.
- Nine common storage mite species were identified, including Acarus siro and Glycyphagus domesticus.
- House dust allergy is a significant public health concern often linked to mite allergens.
Purpose:
- To identify common storage mite species in domestic environments.
- To investigate the allergenic potential of storage mites through skin testing.
- To explore cross-reactivity between storage mites and Dermatophagoides species in allergic individuals.
Summary:
- Nine species of storage mites were identified in granaries and house dust.
- Skin tests were conducted on 14 patients with house dust allergy using extracts from common storage mites (Acarus siro, Glycyphagus domesticus, Lepidoglyphus destructor) and known house dust mites (Dermatophagoides pteronyssinus, Dermatophagoides farinae).
- Findings suggest that sensitization to storage mites may involve cross-reactivity with Dermatophagoides species.
Impact:
- The study highlights the potential role of storage mites as allergens in house dust allergy.
- Understanding cross-reactivity can inform more accurate diagnosis and targeted treatment strategies for allergic patients.
- This research contributes to the broader understanding of indoor allergens and their impact on respiratory health.
