Studies on house dust mites in Great Cairo, Egypt
1Department of Zoology, Faculty of Science, Al Azhar University, Nasr City, Egypt.
Abstract:
Nowadays, house dust mites have showed themselves as one of the health problem worldwide. They have to be considered in the differential diagnosis of allergy particularly in children. House dust mites were collected from eight different areas in Great Cairo. Nine species of mites were recovered from indoors. In order of abundance, they were Dermatophagoides pteronyssinus, D. farinae, Tyrophagous putrescentiae, Acarus siro, Cheyletus malaccensis, Blomia kulagini, Acheles graciles, Ornithonyssus bacoti and Lepidoglyphus destructor. All these mites were collected mainly from Bolak Al Dakrour (28.8%) and Al Wayly (27.6%). The least number (1.8%) and species (only three) were collected from Madent Al Salam. Pet and stray dogs and cats, domestic birds and commensal rodents were more or less reported in the majority of the examined areas. Also, patients with history of allergy of unknown cause, were reported in ten out of 80 houses examined (12.5%). The role played by house dust mites in causing allergic manifestations was important environmental disease agents.
Insights
House dust mites are a significant global health concern, especially for children
Area of Science:
- Environmental Science
- Allergology
- Medical Entomology
Background:
- House dust mites are recognized as a worldwide health issue.
- They are crucial in the differential diagnosis of allergies, particularly in pediatric cases.
- Understanding mite prevalence is vital for public health initiatives.
Purpose of the Study:
- To identify and quantify house dust mite species in various areas of Great Cairo.
- To investigate the association between mite presence and allergic conditions in households.
- To determine the distribution and abundance of indoor mite populations.
Main Methods:
- Mites were collected from eight distinct locations in Great Cairo.
- Species identification and abundance counts were performed for recovered mites.
- Households were surveyed for the presence of pets, domestic animals, and allergic patients.
Main Results:
- Nine species of house dust mites were identified, with Dermatophagoides pteronyssinus and D. farinae being the most abundant.
- The highest mite concentrations were found in Bolak Al Dakrour (28.8%) and Al Wayly (27.6%).
- Madent Al Salam showed the lowest mite presence (1.8%) with only three species.
Conclusions:
- House dust mites are prevalent in indoor environments in Great Cairo.
- The identified mite species play a significant role as environmental agents causing allergic manifestations.
- Further research and control strategies are warranted to mitigate mite-related allergies.
