Escherichia coli translocation in experimental short bowel syndrome: probiotic supplementation and detection by polymerase chain reaction.

Background: After massive bowel resection, bacterial overgrowth is frequent and favors the occurrence of Gram-negative intestinal bacterial translocation (BT). Probiotics have been recommended in several diseases and may also have beneficial effects on BT. Conversely, polymerase chain reaction (PCR) technique has shown better sensitivity than conventional methods in bacterial detection and has not been investigated in experimental models of short bowel syndrome and BT.
