Abstract: | Respiratory allergy affects all age groups but the children are the worst affected by the respiratory allergy. Bioparticles
from different biological sources are the main cause of allergy. Pollen grains, fungal spores, insect and other materials
of biological origin form the most important allergen load in the air. For the efficient diagnosis of the allergy and its
effective treatment it is very important to know about the prevalence, seasonal and annual variations of aeroallergens of
the area. India being the climatically diversed country, there is diversity in the flora and fauna of different parts of the
country. Atmospheric surveys carried out in different parts of India reveal that,Alanus nitida, Amarantus spinosus, Argemone mexicana Cocos nucifera, Betula utilis, Borasus flabellifer, Caraica papaya, Cedrus
deodara, Cassia fistula, Parthenium, Chenopodium album,Dodonaea viscosa, Malotus phillipensis, Plantago ovata, Prosopis juliflora, Ricinus communis, Holoptelea intergifolia are the allergenically important pollens of the country. Among the fungal aeroallergens,Altemaria, Candida aibieans, Aspergillus versicolor, Aspergillus terreus, Aspergillus japonicus, Cladosporium cladosporoides,
Fusarium roseum, Ganoderma lucidum,Neurospora sitophila Helminthosporium, Ustilago trtici, Uromyses are important allergens. Dust mitesD. farinae,D.pteronyssinus are also important source of inhalant allergens particularly in the coastal areas of the country. Cockroaches, beetles, weevils,
mosquitoes, house flies also contribute towards the aeroallergen load and are allergenically implicated. Avoidance of the
indoor and outdoor aeroallergens is recommended for better management of respiratory allergy. |
