Abstract

Nocardiosis is a localized or disseminated infection caused by soil-borne aerobic actinomycetes. Pulmonary nocardiosis is a rare infection mostly occurring in immunocompromised patients. We reported a case of 36 year old immunocompetent non-smoker female patient with no premorbid illness who presented with fever, cough with scanty sputum, hemoptysis, left sided chest pain and exertional dyspnea for two weeks. There was no past history of tuberculosis, diabetes mellitus or steroid therapy. Chest X-ray showed homogenous peripherally based opacity in the left upper zone. Bronchoscopy was done and brushing sent for culture, which showed colonies with features of Nocardia species after 48 hours. Further phenotypic characterization revealed it to be Nocardia otitidiscaviarum. Patient was treated with cotrimaxazole for six months after which complete recovery was evidenced symptomatically and radiologically. We report this case to emphasize the fact that among the Nocardia species, Nocardia otitidiscaviarum as causative agent of pulmonary disease is rarely reported even in immunocompromised individuals.
