Bacterial translocation is currently considered the main pathogenic mechanism leading to spontaneous bacterial peritonitis in patients with advanced cirrhosis and ascites. However, to the authors' knowledge there is no information regarding the characteristics of this process in humans. The goals of the current study were to pursue partially identified bacterial DNA in blood (what the authors c...
BACKGROUND AND AIMS Bacterial infections are common complications in patients with acute pancreatitis, and translocation of bacteria from the intestinal lumen is probably the first step in the pathogenesis of these infections. As blood cultures in afebrile patients are usually negative, more sensitive methods to investigate this hypothesis in patients are needed. Our group has recently develope...
Correspondence to: Professor A K Burroughs, Liver Transplantation and Hepatobiliary, Medicine Unit, Royal Free Hospital, Pond St, London NW3 2QG, UK; Andrew.Burroughs@ royalfree.nhs.uk _________________________ SUMMARY Bacterial infections in cirrhotic patients are common. There is a predisposition to intestinal bacterial overgrowth, intestinal dysmotility, and increased intestinal permeability...
Central to the study of type III secretion systems is the availability of reporter systems to monitor bacterial protein translocation into host cells. We report here the development of a bacteriophage P1 Cre recombinase-based system to monitor the translocation of bacterial proteins into mammalian cells. Bacteriophage P1 Cre recombinase fused to the secretion and translocation signals of Salmon...
Background and aims: Bacterial infections are common complications in patients with acute pancreatitis, and translocation of bacteria from the intestinal lumen is probably the first step in the pathogenesis of these infections.

The bacterial Sec and signal recognition particle (ffh-dependent) protein translocation mechanisms are conserved between prokaryotes and higher plant chloroplasts. A third translocation mechanism in chloroplasts [the proton concentration difference (DeltapH) pathway] was previously thought to be unique. The hcf106 mutation of maize disrupts the localization of proteins transported through this ...
Bacterial translocation from gut has been assumed to be an infectious source in severe acute pancreatitis. The purpose of this study was to test the effect of intraperitoneal administration of oxygenated perfluorochemical on bacterial translocation associated with rat experimental acute necrotizing pancreatitis. Severe necrotizing pancreatitis was induced by retrograde injection of 3% sodium de...
OBJECTIVE To evaluate the effects of different times of ischemic preconditioning (IPC) on intestinal bacterial translocation (BT). METHODS Thirty Wistar rats weighing 280 ± 27 g were divided into five groups. In the IR group (n = 6), laparotomy was performed and the superior mesenteric artery was occluded by an atraumatic microclamp for 30 minutes. In the four preconditioning groups (n = 6 ea...

Burn injury and sepsis produce acute gastrointestinal derangements that may predispose patients to bacterial translocation. We studied the effects of enalapril, an angiotensin converting enzyme inhibitor (ACEI), on gastrointestinal anatomic alterations, bacterial translocation, and related mortality during gut-derived sepsis in burned mice that had received a prior bacterial challenge. BALB/c m...
