Figure 2. Enterotoxigenic Bacteroides fragilis induce colon tumors in multiple intestinal neoplasia mice.
The photograph shows the distal colons of Min mice colonized for 2 months with either NTBF or ETBF. Only ETBF-colonized Min mice display excess gross tumors in colons stained with methylene blue. ETBF, enterotoxigenic Bacteroides fragilis; Min, multiple intestinal neoplasia; NTBF, nonenterotoxigenic Bactersoides fragilis. Reproduced with permission from [23•].
