Plućna infekcija izazvana organizmom Nocardia asteroides: prikaz slučaja

Presentation is made of a 53-year-old woman with pulmonary infection caused by Nocardia asteroides. Tracheal aspirate was obtained and examined microbiologically. Direct smear of the tracheal aspirate stained with Gram stain revealed gram-positive branched filamentous hyphae and numerous leukocytes. Pure culture of colonies of a chalky white appearance grew on the blood agar after prolonged incubation. The Gram stained direct slide prepared from the culture showed gram-positive branching filaments. The microorganism was identified as Nocardia asteroides by standard methods.Prikazana je 53-godišnja bolesnica s plućnom infekcijom uzrokovanom mikroorganizmom Nocardia asteroides.
