Introduction: Pulmonary mycosis is a fungal infection of the lungs caused by either endemic or opportunistic fungi or a combination of both. They comprise a large group of fungal diseases, the etiologic agents are potential pathogens among the immunocompromised or debilitated patients. Objective: The study aims to identify the occurrence of pulmonary mycoses in clinically suspected cases of pulmonary tuberculosis .by isolating the fungi and identifying the various fungi causing pulmonary mycoses. Methods: Two hundred sputum samples were collected from 100 patients who were clinically suspected to have pulmonary tuberculosis. Acid Fast staining was performed to identify the presence of Acid Fast Bacilli (AFB). Potassium hydroxide (KOH) mount also performed separately to examine the presence of fungal elements. Gram stain was performed to identify the presence of bacteria and fungi elements. All the samples were cultured on Sabouraud__ampersandsignrsquo;s Dextrose Agar (SDA) slants to study the morphology of the fungal colony. A germ tube test was performed to identify Candida albicans. Lacto Phenol Cotton Blue tease mount preparations were made to identify the morphological feature of fungal components in culture. Results: The results were analyzed and various types of pathogens were detected. Out of 100 patients, 29 showed positive reports. Among the 29 cases, eight were positive for AFB, while fungus as a primary etiological agent was detected in 10 patients. Fungus as a secondary etiological agent was detected in 4 patients [AFB with fungus]. Bacteria as the primary cause of pulmonary infection were detected in 7 patients. The isolated fungi as the primary pathogen in clinically suspected cases of pulmonary tuberculosis were Candida species in 6% and Aspergillus species in 4% of patients. Conclusion: Pulmonary mycosis may be a primary infection in non-tuberculosis cases or co-infection in pulmonary tuberculosis. Therefore Pulmonary mycoses can be easily misdiagnosed and mistreated as pulmonary tuberculosis. Investigation for fungal cause in clinically suspected cases of pulmonary tuberculosis will prevent this type of misdiagnosis and management. The present study indicates that fungal aetiology should also be sought in all clinically suspected pulmonary tuberculosis patients.
