[Disseminated nocardiosis caused by Nocardia otitidiscaviarum in an immunocompetent host: a case report].

Nocardiosis can be caused by various Nocardia spp., including Nocardia asteroides, Nocardia brasiliensis, Nocardia cyriacigeorgica, Nocardia farcinica and Nocardia otitidiscaviarum. As compared with the other Nocardia spp., Nocardia otitidiscaviarum appears to be rare which can spread through the bloodstream and affect multiple organs. The disease is usually seen in immunocompromised patients' but may also occur in immunocompetent patients. The clinical symptoms and laboratory and imaging examinations of the disease are nonspecific.Here, we reported a case of disseminated nocardiosis caused by infection with Nocardiosis otitidiscaviarum in an immunocompetent host to improve the knowledge and diagnosis of nocardiosis.
