Bacterial translocation, the passage of viable indigenous bacteria from the gastrointestinal tract to the mesenteric lymph nodes and other internal organs, has been poorly studied in man to date. Pericolonic lymph nodes, liver, portal blood, and peritoneum specimens were harvested before antibiotics were administered during 20 operations for colorectal cancer and compared with those obtained in 20 operations for non colorectal conditions. Bacterial translocation, defined as the presence of intestinal bacteria in at least one of the specimens, was found in 13 patients (65 percent) in the colorectal cancer group as compared to 6 (30 percent) in the control group (p less than 0.05). The increased incidence of bacterial translocation in colorectal cancers was mainly due to the presence of bacteria in the pericolonic lymph nodes adjacent to the cancer. These findings suggest that intestinal bacteria translocate from the bowel lumen in a high proportion of patients with colorectal cancer and further stress the need for prophylactic antibiotics in colorectal cancer surgery.

Adenosine triphosphate (ATP)-binding cassette (ABC) transporter systems are divided into importers and exporters that facilitate the movement of diverse substrate molecules across the lipid bilayer, against the concentration gradient. These transporters comprise two highly conserved nucleotide-binding domains (NBDs) and two transmembrane domains (TMDs). Unlike ABC exporters, prokaryotic ABC importers require an additional substrate-binding protein (SBP) as a recognition site for specific substrate translocation.

Bacterial-fungal interaction (BFI) has significant implications for the health of host plants. While the diffusible antibiotic metabolite-mediated competition in BFI has been extensively characterized, the impact of intercellular contact remains largely elusive. Here, we demonstrate that the intercellular contact is a prevalent mode of interaction between beneficial soil bacteria and pathogenic filamentous fungi.

Background Severe acute pancreatitis (SAP) manifests as a critical state marked by acute abdominal symptoms, often associated with intestinal barrier dysfunction, exacerbating SAP retroactively. Ganoderic acid A (GAA) demonstrates anti-inflammatory properties in various inflammatory disorders. Nonetheless, its potential therapeutic impact on SAP and the underlying mechanisms remain unexplored.

Introduction: The low incidence of intradialytic hypotension (IDH) in high-volume (HV) hemodiafiltration (HDF) may help in maintaining gut perfusion during treatment. Preservation of gut endothelial integrity would limit or prevent bacterial translocation and subsequent systemic inflammation, which may contribute to the low mortality rate in HV-HDF.
Methods: Forty patients were cross-over randomized to standard (hemodialysis [HD]) (S-HD), cool HD (C-HD), and HDF (low-volume [LV] and HV, convection volume (CV) of 15 L and ≥ 23 L per session, respectively), each for 2 weeks.
