Fig. 4From: Genotyping of a gene cluster for production of colibactin and in vitro genotoxicity analysis of Escherichia coli strains obtained from the Japan Collection of MicroorganismsDose-dependent induction of micronuclei in CHO AA8 cells infected with clb+E. coli. Mean ± SD values of at least three independent experiments are shown. MOI = 0 represents the vehicle control. * indicates p < 0.05 and ** indicates p < 0.01 (versus that of MOI = 0) according to the t-testBack to article page
