Alphabetical Test listing

Nocardia culture, stain-12425

Nocardia culture, stain
  • Culture
  • Acid-fast stain
  • Identification, susceptibilities and serogrouping will be performed on all microbiology isolates considered by the laboratory to be significant

Nocardia species are bacteria found in soil and water, and their isolation in culture may represent colonization of the skin or upper respiratory tract, rather than infection. Infections result from trauma-related inoculation or inhalation. In the immunocompetent, Nocardia, predominantly N. brasiliensis, causes chronic subcutaneous infection (mycetoma), lymphocutaneous infections, skin abscesses, or cellulitis. In immunocompromised patients, Nocardia can cause invasive pulmonary infections and disseminated infections, including brain and skin lesions. More than 80% of Nocardia infections are caused by N. asteroides


Multiple specimens should be collected for recovery of Nocardia in culture (3 early morning specimens collected on separate days). In mycetomas, sinus tract drainage and granules (microcolonies) are recommended for direct exam and culture.
