Molecular identification and susceptibility pattern of clinical Nocardia species: Emergence of Nocardia crassostreae as an agent of invasive nocardiosis.

Background: Nocardia species are rare, opportunistic organisms that cause disease in both immunocompetent and immunocompromised individuals.

Objective: To investigate the clinical presentations of various Nocardia infections based on the 16S ribosomal RNA gene of the isolate, as well as related risk factors and susceptibility patterns to antimicrobial agents.

Methods: Thirteen patients with a diagnosis of nocardiosis were included in the present study.
