Abstract
The present study has been carried out to assess the allergenicity of dominant pollen types from the atmosphere of nine districts of the state of Punjab, India. During the study period (2012–2014), 30 different kinds of pollens belonging to 17 families were recorded. Antigenic extract of thirteen pollen types were selected for skin prick tests (SPT). The allergenic pollens selected for the present study belong to families: Asteraceae, Amaranthaceae, Brassicaceae, Cannabaceae, Chenopodiaceae, Meliaceae, Moraceae, Myrtaceae and Xanthorrhoeaceae. Total 165 sensitized patients having diagnosed with bronchoprovocation test were selected for SPT. Diagnostic tests were performed in ENT department, Rajindra hospital Patiala, and SPT were done in the clinic of Dr. H.S. Bedi at Patiala. Antigenic reactivity (3+ to above) to various allergens varied from 2.4 to 9.09 %. Patients showed maximum allergenic sensitivity to Parthenium hystrophorus (9.09 %) followed by Morus alba (8.48 %), Amaranthus spinosus (7.87 %) and Ageratum sp. (6.06 %). Least reactivity was shown by Brassica compestris and Eucalyptus sp. (2.4 %).
