Mycobacterium kansasaii and Mycobacterium scrofulaceum dual pulmonary infection in an immunocompetent male: first report from India

Abstract

A 57-year-old farmer presented with chronic cough and recurrent hemoptysis, previously treated for sputum positive pulmonary tuberculosis. Referred to us for evaluation of drug resistant tuberculosis as his sputum was persistently positive for acid fast bacilli along with radiological worsening even after 6 months of antitubercular treatment. Bronchoalveolar lavage was done and he was diagnosed with a rare mixed non-tuberculous mycobacyteria (NTM) pulmonary infection despite no immune dysfunction. He was successfully treated with multidrug regimen of rifampicin, isoniazid, ethambutol and clarithromycin.
