MAIN EDUCATIONAL POINTS from M174-5
- Nocardia is a potential pathogen especially in immunocompromised hosts, and should be considered when gram positive bacilli with a beaded/branching appearance are visualized on Gram stain or grown.
- Nocardia may be presumptively reported in such organisms if the modified acid-fast stain is positive, and the acid-fast stain is negative.
