Rachna Chaturvedi and Sushil Chaturvedi

Abstract

The present survey was conducted to observe allergic effect of various fungi in patients of respiratory allergy of terai area.Terai area has humid, subtropical climate, warm in winter and hot in summer total of 96 patients were studied after full clinical examination.
