Characterization of Bacterial Metabolites Involved in Host Pathogen Resistance
<p>The intestinal microbiome can mediate host resistance to enteric pathogens by modulating host immunity or by directly inhibiting pathogen growth and virulence. Although the abundance and diversity of bacterial metabolites in the intestine is appreciated, the majority of intestinal bacteria and …

The usefulness of multiple antibiotic resistance (MAR) indexing technique in differentiating fecal coliform bacteria from different sources
… sources with human fecal matter and associated intestinal pathogens poses a great risk to public health. Fecal contamination of water is not the only problem to communities that consume untreated water. The extent of the microbial contamination of water sources also needs to be considered when …

Epithelial Cell Autophagy in Antibacterial Defense of the Small Intestine
… resident bacteria opportunistically invade the intestinal barrier, leading to pathologies such as inflammatory bowel disease (IBD), and bacteremia. As a result, epithelial cell innate immune responses play an essential role in preventing bacterial invasion of host tissues and maintaining a …

Inflammasomes in the Intestinal Epithelium
… inflammasomes are critical for controlling intestinal pathogens and regulating epithelial-mucosal homeostasis, little is known about how they function in this cellular compartment. Moreover, very few studies focus specifically on inflammasomes in human cells, and this has implications for …

Molecular characterisation of selected gastrointestinal microbiota in South African HIV-positive patients during HAART
… diarrhoea due to the disruption of the gastrointestinal microbiota caused by either the HIV-infection or the use of antibiotics and drugs such as highly active antiretroviral therapy (HAART). An imbalance in the microbial composition, attributable to a disturbed mucosal barrier, as well as …

Characterisation of the role of Fas in intestinal inflammation and cancer
… cross-talk between TLRs and Fas/FasL system in intestinal cancer cells. Results: Treatment with TLR4 and TLR5 ligands, but not ligands for TLR2 and TLR9 increased the expression of Fas and FasL in intestinal cancer cells in vitro. Consistent with this, expression of Fas and FasL was reduced in …
