Lm. Shah et al., ENHANCED IN-VITRO ACTIVITY OF PYRIMETHAMINE IN COMBINATION WITH DAPSONE AGAINST MYCOBACTERIUM-AVIUM COMPLEX, Antimicrobial agents and chemotherapy, 40(10), 1996, pp. 2426-2427
The in vitro activities of pyrimethamine and dapsone alone and in comb
ination were evaluated against 23 clinical isolates of Mycobacterium a
vium complex. The broth dilution MICs of dapsone and pyrimethamine alo
ne ranged from 16 to >64 mu g/ml. Pyrimethamine in combination crith a
fixed concentration of dapsone at 0.5 mu g/ml showed enhanced activit
y, with an MIC range of 0.5 to 16 mu g/ml.
