Nocardia

Colonies of Nocardia asteroides

Nocardien ( named after the French infectiologists Edmond Nocard ) are rod- shaped, Gram-positive bacteria. They often grow branches and are partially similar to mycobacteria by acid not again decolorized ( acid-resistant ). Nocardia are ubiquitous in soil and wetlands. They grow well at 30 ° C, and some can cause in humans and animals Nocardiosen.

Diseases

Nocardien be absorbed through the lungs. In humans, only diseases of immunosuppressed by this pathogen are known. It comes first for pulmonary nocardiosis with bronchial pneumonia and lung abscess. From there, they can use the blood ( hematogenous ) in various organs scatter (systemic nocardiosis ). The excitation preferred attack the CNS and encephalitides and solve brain abscesses from. Nocardia can also cutaneous and subcutaneous abscesses trigger (superficial nocardiosis ). The latter is mainly caused by Nocardia brasiliensis.

Therapy

Antibiotic therapy with co-trimoxazole and doxycycline. As a reserve antibiotic imipenem and amikacin are available.
