Nocardia transvalensis Disseminated Infection in an Immunocompromised Patient with Idiopathic Thrombocytopenic Purpura

الملخص EN

Nocardia transvalensis complex includes a wide range of microorganisms with specific antimicrobial resistance patterns.

N.

transvalensis is an unusual Nocardia species.

However, it must be differentiated due to its natural resistance to aminoglycosides while other Nocardia species are susceptible.

The present report describes a Nocardia species involved in an uncommon clinical case of a patient with idiopathic thrombocytopenic purpura and pulmonary nocardiosis.

Microbiological and molecular techniques based on the sequencing of the 16S rRNA gene allowed diagnosis of Nocardia transvalensis sensu stricto.

The successful treatment was based on trimethoprim-sulfamethoxazole and other drugs.

We conclude that molecular identification of Nocardia species is a valuable technique to guide good treatment and prognosis and recommend its use for daily bases diagnosis.
