B. Watt et al., COMPARATIVE ACTIVITY OF AZITHROMYCIN AGAINST CLINICAL ISOLATES OF MYCOBACTERIA, Journal of antimicrobial chemotherapy, 38(3), 1996, pp. 539-542
Azithromycin exhibited in-vitro activity against 20 clinical isolates
of Mycobacterium avium complex for which the MIC(90) was 32 mg/L and 2
2 clinical isolates of other mycobacteria but showed no activity again
st 20 isolates of Mycobacterium tuberculosis (MIC(90) > 128 mg/L) nor
against the single isolate of Mycobacterium marinum tested (MIC 128 mg
/L). These results suggest that the drug may prove useful for the prop
hylaxis and treatment of infections due to non-tuberculous mycobacteri
a, including M. avium complex in patients with AIDS.
