Abstract excerpt
Cultivation of E. coli B/r strain WP2 in low concentrations of either 4-nitroquinoline N-oxide (4NQO) or N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) had no effect on the mutagenic or cytotoxic consequences of subsequent challenge with dichlorvos (DCV). However, although the sensitivity of E. coli cells taken from cultures grown in low concentrations of DCV to the effects of 4NQO was unchanged, the cells were more...
