Objective. The aim of this study was to compare spontaneous and induced rates in mice of both sexes of lines BALB / c, NMRI, OF-1 and C57BL/6/ cenp, by testing chromosomal aberrations in bone marrow cells. Materials and methods. For this purpose, the most efficient line was determined, based on the significant appearance of lower spontaneous rates and higher induced rates to mutagen substances such as cyclophosphamide (CP). Results. The result obtained was that line Balb / c, in both sexes, differs significantly from the other lines tested. The lesser total number of cells with structural aberrations was found in this line and a greater number of induction of chromosomal aberrations when CP was used as a mutagen. Conclusions. This work will give way to the use of the best line of mice as bio model in this genotoxicity test, and will also give this cytogenetic technique greater veracity and robustness.
