UNLABELLED Clostridium difficile is the cause of most frequently occurring nosocomial diarrhea worldwide. As an enteropathogen, C. difficile must be exposed to multiple exogenous genetic elements in bacteriophage-rich gut communities. CRISPR (clustered regularly interspaced short palindromic repeats)-Cas (CRISPR-associated) systems allow bacteria to adapt to foreign genetic invaders. Our recent...

This study was undertaken to assess the potential of Non-Starter Lactic Acid Bacteria (NSLAB) from Cheddar cheese survive gastric transit and display probiotic-related traits including bile salt hydrolase activity, ability adhere gut epithelium inhibition enteropathogen binding. Populations NSLAB, up 107 CFU/g per were recovered following exposure Simulated Stomach Duodenum Passage (SSDP) condi...

In regions with a high infectious disease burden, concerns have been raised about the safety of iron supplementation because higher iron concentrations in the gut lumen may increase risk of enteropathogen infection. The aim of this study was to investigate interactions of the enteropathogen Salmonella enterica ssp. enterica Typhimurium with intestinal cells under different iron concentrations e...

The intestinal ecosystem is formed by a complex, yet highly characteristic microbial community. The parameters defining whether this community permits invasion of a new bacterial species are unclear. In particular, inhibition of enteropathogen infection by the gut microbiota ( = colonization resistance) is poorly understood. To analyze the mechanisms of microbiota-mediated protection from Salmo...

Pathogenic Yersinia translocates effector proteins into target cells via a type III secretion system (TTSS), modulating the host immune response. A component of the TTSS translocon, LcrV, has been implicated in preventing inflammation through Toll-like receptor 2 (TLR2) by inducing expression of the anti-inflammatory cytokine interleukin-10 (IL-10). TLR2(-/-) mice were reported to be less susce...

Escherichia albertii is a new enteropathogen of humans and animals. The aim the study was to assess prevalence pathogenicity E. strains isolated in northeastern Poland using epidemiological genomic studies. In 2015–2018, total 1154 fecal samples from children adults, 497 bird droppings, 212 food samples, 92 water 500 lactose-negative coli were tested. A 42 isolated. PCR method suitable for thei...
