[The role of intestinal microflora and probiotic bacteria in prophylactic and development of colorectal cancer].

The gut microbiota comprises a large and diverse range of microorganisms whose activities have a significant impact on health. It interacts with its host at both the local and systemic level, resulting in a broad range of beneficial or detrimental outcomes for nutrition, infections, xenobiotic metabolism, and cancer. The current paper reviews research on the role of intestinal microflora in colorectal cancer development.
