Introduction: Fungi constitute a large diverse group of heterotrophic organisms, most of which are found as saprophytes in the soil and decaying plant material. They are eukaryotes with nearly 50,000 species. They are essential in breaking down and recycling of organic matter. Some species contribute to the production of food, spirits, antibiotics and an array of enzymes. Incidence of fungal infections has been grossly underestimated. Fungal infections are on the increase due to improved survival of immuno suppressed patients and better diagnostic facilities. Only 100 to 150 species are generally recognized as a cause of disease in humans. The present study was aimed at finding out the common fungus, predisposing factors for Otomycosis and doing drug susceptibility of the fungi isolated for Clo-trimazole. This was done at Government Rajaji Hospital attached to Madurai Medical College for a period of one and half year from 2005 to 2006. Conclusion: The incidence of Otomycosis is more during monsoon period. Males are more affected. Unilateral incidence of disease is common. CSOM is the most common predisposing factor. Aspergillus flavus is the most common fungal isolate. Aspergillus flavus is the most common isolate in agriculturists and labourers. (outdoor workers). Aspergillus niger is the common fungal isolate in females. A. flavus, A. niger, A. fumigatus and A. glaucus and candida are sensitive to Clo-trimazole drops. The frequency of recovery of certain fungal species such as A. flavus, A. niger, A. terreus and Candida albicans from Otomycosis reflects the great ubiquity of the distribution of their spores and hence exposure to them. Systemic illness play an important role in the recurrence of otomycosis. Inadequate aural toilet plays a role in recurrence.
