ABSTRACT
This work is focused on the aerobiology and allergenicity of Fomes pectinatis in India. The atmospheric concentration of Fomes basidiospores was recorded and the antigens were prepared from spore (FSE) and whole body (FWBE) materials. The intradermal (ID) and prick (PT) skin tests were conducted on 172 patients having respiratory allergy. The period from July to October has been recorded as having a higher concentration of Fomes spores. The maximum counts (67 spores/m3) were observed from the North Delhi site in the month of July, 1989, compared with 550 spores/m3 in the South Delhi site. Marked skin positivity (2+ and above) varied from 9.8% to FSE to 22% to FWBE. Nine out of twelve ID positive patients (2+ to 3+) to FSE also gave PT positive response. For FWBE, similar ID and PT response was obtained in 80% of cases. The soluble protein content of FSE was 0.37 mg/ml, whereas, for FWBE it was 0.70 mg/ml. It was observed through ELISA that almost all patients had significantly raised FP specific IgE levels in their sera. The current study, therefore, indicates that Fomes pectinatis may be a prevalent aeroallergen in India.
