Core Tip
Core Tip: In this review, we describe oral and gut microbiome associated with colorectal (CRC) carcinogenesis in relation to the “hallmarks of cancer” and microbial diversity and abundance between races/ethnicities. CRC patients showed increased levels of Bacteroides, Prevotella, Escherichia coli, enterotoxigenic Bacteroides fragilis, Streptococcus gallolyticus, Enterococcus faecalis, Fusobacterium nucleatum (F. nucleatum) and Clostridium difficile. Higher levels of Bacteroides, F. nucleatum and Enterobacter species have been found in African American (AA) compared to Caucasian American (CA) CRC patients. Also, AA patients had decreased microbial diversity compared to CA patients. Periodontal-associated bacteria, Fusobacterium, Prevotella, Bacteroides and Porphyromonas, have been found in CRC tissues and in feces of CRC patients.
