Mucosal surfaces, such as the lung and intestine, are lined by a monolayer of epithelia that provides tissue barrier and transport function. It is recently appreciated that a common feature of inflammatory processes within the mucosa is hypoxia (so-called inflammatory hypoxia). Given the strong association between bacterial translocation and mucosal inflammatory disease, we hypothesized that in...
OBJECTIVE Bacterial translocation (BT) or bacterial DNA (bactDNA) translocation is a critical pathogenesis mechanism of spontaneous bacterial peritonitis. Studies of BT or bactDNA translocation are limited in humans. Neutrophil gelatinase associated lipocalin (NGAL) can efficiently distinguish bacterial and nonbacterial ascites in ascitic patients. Hepcidin is a useful marker of bacterial infec...
Bacterial attachment to surfaces or association to other bacterial species is an important subject for understanding the complex bacterial communities that populate the intestinal tract. Disruption of these ecologically stable communities can lead to harmful effects for the host, i.e. permitting the access of opportunistic or newly arrived pathogens to sterile areas of the body producing diseas...
Proper cell function relies on correct protein localization. As a first step in the delivery of extracytoplasmic proteins to their ultimate destinations, the hydrophobic barrier presented by lipid-based membranes must be overcome. In contrast to the well-defined bacterial and eukaryotic protein translocation systems, little is known about how proteins cross the membranes of archaea, the third a...
Besides being one of the mechanisms responsible for ventilator-induced lung injury, atelectasis also seems to aggravate the course of experimental pneumonia. In this study, we examined the effect of reducing the degree of atelectasis by natural modified surfactant and/or open lung ventilation on bacterial growth and translocation in a piglet model of Group B streptococcal pneumonia. After creat...
Probiotics can prevent pathological bacterial translocation by modulating intestinal microbiota and improving the gut barrier. The aim was to evaluate the effect of a fermented milk containing Lactobacillus paracasei subsp. paracasei CNCM I-1518 on bacterial translocation in rats with carbon tetrachloride (CCl4)-induced cirrhosis. Sprague-Dawley rats treated with CCl4 were randomized into a pro...
Stress is known to be one of the risk factors of stroke, but only a few experimental studies have examined the possible mechanisms by which prior stress may affect stroke outcome. In stroke patients, infections impede neurological recovery and increase morbidity as well as mortality. We previously reported that stress induces a bacterial translocation and that prior immobilization stress worsen...
