Abstract: Colorectal cancer (CRC) is the third most prevalent malignant neoplasm in the world.
CRC is influenced by both environmental and genetic factors. Through toxin-mediated DNA damage
and the promotion of persistent dysregulated inflammation, the gut microbiota plays a crucial role in
the development of CRC. In this review, we discussed the correlation between the bacterial microbiota
and CRC carcinogenesis as well as the mechanism by which Streptococcus bovis/gallolyticus,
Fusobacterium nucleatum, Bacteroides fragilis, and Escherichia coli can cause CRC.
