Yi Xu and colleagues look at the role of Streptococcus gallolyticus subsp. gallolyticus (Sg) in the development of colorectal cancer (CRC). They reveal that Sg is present in most CRC patients and introduce the tumor-promoting role of Sg that involves specific bacterial and host factors. The results provide greater insight in understanding the relationship between Sg and CRC.
