 AB    BACKGROUND: To assess the utility of Bactec non-radiometric system in
       detecting disseminated mycobacteremia. METHODS: Blood cultures are
       processed using the Bactec NR 660/HPS system. Incubation of the NR6A
       vials, from HIV infected patients, is prolonged for 6 weeks and read
       once a week. After the 14th day of incubation a growth value > or = 30
       is considered positive. RESULTS: Mycobacteria were recovered from 80
       blood cultures from 32 human immunodeficiency virus infected patients.
       The mean time required to detect growth was 37.8 days (range 20-45).
       Mycobacterium tuberculosis was isolated from 18 patients and
       Mycobacterium avium from 14. In 12 patients (37.5%) blood culture was
       the first or the only positive specimen. CONCLUSIONS: Prolonged
       incubation of NR6A medium has proved to be a suitable method for
       detecting mycobacteremia.
