Abstract
Sputum and bleed samples were analysed from 330 cases of bronchial asthmatics and 50 normal persons without features of bronchial asthma. The prevalence of aspergilli and antibodies to different Aspergillus species were detected using cultural methods and serological technique like agar gel double diffusion (DD), counter-immuno-electrophoresis (CIEP) and enzyme-linked immunosorbent assay (ELISA). Out of total 6.06% yielded Aspergillus species in sputum specimens repeatedly. Precipitins against Aspergillus species were detected in 7.88% of cases by DD and CIEP. ELISA test showed 20% of cases to be having antibodies to A. fumigatus. Allergic broncho-pulmonary aspergillosis can be detected in the early course of the disease in bronchial asthmatics using highly sensitive technique like ELISA.
