Effects of antituberculosis and antileprosy drugs on mycobacteriophage D29 growth.
The minimal inhibitory concentrations of antituberculosis and antileprosy drugs were determined for Mycobacterium aurum. The concentrations that reduced the final yield of bacteriophage D29R1 by 50% and the time during the replication cycle at which the drugs completely inhibited phage production were estimated. THe 50% inhibitory concentration/minimal inhibitory concentration ratios were close to 1.0 for clofazimine, colistin, rifampin, and streptomycin; these ratios were high for dapsone (diaminodiphenylsulfone) and isoniazid. Ethambutol (minimal inhibitory concentration, 1.0 micrograms/ml) was without effect on viral growth.
