Dominant lethal study in male mice treated with ofloxacin, a new antimicrobial drug. 1985

H Shimada, and Y Ebine, and T Sato, and Y Kurosawa, and T Arauchi

Ofloxacin (OFLX) in a single dose (250 or 2500 mg/kg) or 5 consecutive daily doses (125 or 1250 mg/kg) produced no dominant lethal mutational effects in male BDF1 strain mice during an 8-week mating schedule. Methyl methanesulfonate (MMS), used as a positive control, produced dominant lethal mutations within 1-3 weeks of mating.

D005804 Genes, Lethal Genes whose loss of function or gain of function MUTATION leads to the death of the carrier prior to maturity. They may be essential genes (GENES, ESSENTIAL) required for viability, or genes which cause a block of function of an essential gene at a time when the essential gene function is required for viability.
