Mucosa-associated microbiota dysbiosis in colitis associated cancer.

ABSTRACT: Gut microbiota dysbiosis has been associated with inflammatory bowel diseases (IBD). In colorectal cancer, the gut microbiota has also been recognized as potentially involved in aggravating or favoring the tumor development. However, very little is known on the structure and role of the microbiota in colitis associated cancer (CAC), an important complication of IBD in human. Here we analyzed the bacterial and fungal composition of the mucosa associated microbiota of patients suffering CAC, sporadic cancer (SC) and of healthy subjects (HS) by barcode sequences analysis on the following cohort: 7 CAC patients, 10 SC patients and 10 HS using 16S (MiSeq) and ITS2 (pyrosequencing) sequencing, for bacteria and fungi respectively. Mucosa-associated bacterial microbiota in CAC was significantly di
