Pulmonary Nocardiosis in a Non-Immuncompromised Patient with Bronchiectasis

Introduction: Nocardia spp are found worldwide ubiquitous in the environment, forming part of the usual microbiota of soil and water as saprophytes. About 25 species are causing human infections. Nocardia spp belong to the aerobic actinomycetes group of bacteria which are gram-positive and weakly acid-fast bacilli showing branching filamentous (“fungal”) pattern. Human infections are infrequent, most of the patients are immunocompromised (1). Inhalation of the bacteria can result in pulmonary nocardiosis, i.e. pneumonia, lung abscess, and cavitary lesions. Contact of the bacteria with abraded skin causes cutaneo…
