The present paper deals with the results of an exploratory study of 52 house-dust samples taken randomly between April-September, 1982, from 30 houses in Bombay occupied by persons with or without suspected respiratory allergy to house-dust. Out of 52 house-dust samples examined for the presence of mites by the floatation method, 48 samples were found to contain mites. The most common species was Dermatophagoides farinae which was particularly abundant in floor-dust followed by Dermatophagoides pteronyssinus which showed dominating occurrence in matress-dust of allergic patients. Other than mites, allergenic pollen and fungal spores were also detected in the dust samples.
