Study Design: Normal rats and paraplegic rats with and injured spinal cord were used to study bacterial translocation from gut.
Objective: To investigate whether bacterial translocation from gut occurs after spinal cord injury.
Summary Of Background Data: It has been demonstrated that trauma and operation can lead to gastrointestinal paralysis; disturbance of gastrointestinal motility following trauma may cause bacterial overgrowth in gastrointestinal tract and increase the incidence of bacterial translocation. However, bacterial translocation from gut after spinal cord injury has not been studied.
Methods: Under aseptic manipulation, samples of blood were collected for bacterial cultures and endotoxin determination. In the meantime, samples of mesenteric lymph node, spleen, and liver were collected for bacterial culture. The jejunum and ileum were observed by light and electron microscope.
Results: Endotoxemia and bacterial translocation appeared 24 hours and 48 hours correspondingly after spinal cord injury complicated with paraplegia.
Conclusion: Bacterial translocation from gut would occur after spinal cord injury in rats, which indicated that antibiotics should be administered to paraplegic patients with spinal cord injury as soon as possible to prevent potential bacterial translocation.

Aim: This study was dedicated to investigating the role of sulfur metabolic processes in sulfate-reducing bacteria in plant resistance to heavy metal contamination.
Methods And Results: We constructed sulfate-reducing bacterial communities based on the functional properties of sulfate-reducing strains, and then screened out the most effective sulfate-reducing bacterial community SYN1, that prevented Cd and Pb uptake in rice through hydroponic experiment. This community lowered Cd levels in the roots and upper roots by 36.
Our current understanding of protein folding is based predominantly on studies of small (<150 aa) proteins that refold reversibly from a chemically denatured state. As protein length increases, the competition between off-pathway misfolding and on-pathway folding likewise increases, creating a more complex energy landscape. Little is known about how intermediates populated during the folding of larger proteins affect navigation of this more complex landscape.

Bacterial translocation-induced inflammation and immune dysfunction are recognised factors contributing to the pathogenesis of primary biliary cholangitis (PBC). However, the specific involvement of interferons (IFNs) and soluble checkpoints (sol-CRs) in shaping the immune landscape in PBC patients remains unexplored. Furthermore, the influence of ursodeoxycholic acid (UDC) on these immune mediators is unknown.

The type III secretion system (T3SS) is a nano-machine that allows Gram-negative bacteria to alter eukaryotic host biology by directly delivering effector proteins from the bacterial cytoplasm. Protein delivery based on the bacterial T3SS has been widely used in research in biology. This review explores recent advancements in the structure and function of the T3SS.
