High Prevalence of Mucosa-Associated E. coli Producing Cyclomodulin and Genotoxin in Colon Cancer (original) (raw)
Figure 3
DNA damage was detected by the comet assay in HeLa cells exposed to E. coli for 3 h.
DNA damage was not detected in HeLa cells infected with the E. coli strain IHE3034 Δ_clbP_ harboring a defective pks island (A). Comet assay was positive in HeLa cells infected with the E. coli strain IHE3034 harboring pks island (B) or with E. coli devoid of known cyclomodulin-encoding genes (C).
