Pollen, Fungus and House Dust Mites Survey at the Residence of 90 Allergic Patients in Greater Silchar Area of Assam, India

Dhruba Sharma, B.K. Dutta and A.B. Singh

In the present study, the quality and quantity of atmospheric pollen, fungus and house dust mites was evaluated at the residence of 90 allergic patients in Greater Silchar area of Assam, India. Atmospheric pollen and fungal survey was done using volumetric Burkard personal slide sampler and volumetric Andersen sampler, respectively. Dust mites survey was done by collecting 500 mg of house dust sample from bed and floor of 90 atopic allergic patient`s residence. Atmospheric pollen concentration was found to be higher in outdoor environment as compared to the indoor air. The dominant pollen types recorded were Poaceae followed by Allium sp., Cocos nucifera, Cassia sp. etc. In contrast, the fungal concentration was found higher inside the patient room as compared to the outdoor air. The dominant fungal genus recorded were Aspergillus sp., followed by Botrytis sp., Cladosporium sp. etc. The dominant house dust mites recorded were Blomia sp., Dermatophagoides sp., Chyletus sp. and Acharus sp. No significant difference was found between the indoor and outdoor pollen and fungal types. Similar kind of result was recorded in the distribution of floor and bed mites` population. Patients showing higher indoor biopollutants were found to be suffering from severe respiratory allergic disorders which indicate that some of the indoor fungus, pollens and dust mites could be responsible for eliciting allergic response in respective patients.
