Clinical Information
Nocardia species and other aerobic actinomycetes can cause significant disease in immunocompromised patients. Clinical presentations can include, but are not limited to, pneumonia, skin abscess, bacteremia, brain abscess, eye infection, and joint infection.
The modified acid-fast stain can detect Nocardia species and other partially-acid fast aerobic actinomycetes directly from clinical specimens.
Reference Values
Reported as positive or negative
Cautions
Artifacts may exhibit nonspecific staining and be confused with organisms. Not all aerobic actinomycetes stain as partially acid-fast. A negative stain does not rule out the possibility of infection and culture should be performed. Nocardia species and other aerobic actinomycetes grow well on mycobacterial culture medium so CTB / Mycobacteria and Nocardia Culture, Varies should be ordered. Sometimes, Nocardia species can also be recovered in fungal cultures (FGEN / Fungal Culture, Routine).
