TLDR
The mechanisms that regulate the ability of the microbiota to restrain pathogen growth are complex and include competitive metabolic interactions, localization to intestinal niches and induction of host immune responses.Abstract:
A dense resident microbial community in the gut, referred as the commensal microbiota, coevolved with the host and is essential for many host physiological processes that include enhancement of the intestinal epithelial barrier, development of the immune system and acquisition of nutrients. A major function of the microbiota is protection against colonization by pathogens and overgrowth of indigenous pathobionts that can result from the disruption of the healthy microbial community. The mechanisms that regulate the ability of the microbiota to restrain pathogen growth are complex and include competitive metabolic interactions, localization to intestinal niches and induction of host immune responses. Pathogens, in turn, have evolved strategies to escape from commensal-mediated resistance to colonization. Thus, the interplay between commensals and pathogens or indigenous pathobionts is critical for controlling infection and disease. Understanding pathogen-commensal interactions may lead to new therapeutic approaches to treating infectious diseases.read more

TL;DR: PPI use was the only modifiable factor significantly associated with diverticulitis, but not with its severity, among patients with Diverticulosis, and this observation should be confirmed in future multicenter prospective studies.

TL;DR: Wang et al. as mentioned in this paper used 16-RNA sequencing technology to detect and analyze upper respiratory flora of TB patients with anti-TB drug sensitivity (DS, n = 55), monoresistance isoniazide (MR-INH), rifampin (RFP), multidrug resistance (MDR), n = 26), and polyresistance (PR), in southern China.

TL;DR: The authors showed that colonisation of mice with a segmented filamentous bacterium (SFB) is sufficient to induce the appearance of CD4+ T helper cells that produce IL-17 and IL-22 (Th17 cells) in the lamina propria.

TL;DR: The infusion of donor feces was significantly more effective for the treatment of recurrent C. difficile infection than the use of vancomycin and patients showed increased fecal bacterial diversity, similar to that in healthy donors, with an increase in Bacteroidetes species and clostridium clusters IV and XIVa and a decrease in Proteobacteria species.

TL;DR: It is found that lateral gene transfer is far more extensive than previously anticipated and 1,387 new genes encoded in strain-specific clusters of diverse sizes were found in O157:H7, including candidate virulence factors, alternative metabolic capacities, several prophages and other new functions—all of which could be targets for surveillance.
