Abstract excerpt
The nitroimidazole derivatives used in human therapy have shown a strong mutagenic activity in bacterial tests using Ames strains of Salmonella typhimurium. Our study compared the response of 4 products of this family on bacterial target cells as well as on mammalian target cells (Chinese hamster V79 cells). The strong positive response on TA100 was greatly reduced on the nitroreductase-deficient strain TA100...
