recommendations! Published in 2020 at "Cellular and Molecular Life Sciences"

DOI: 10.1007/s00018-020-03514-x

Abstract: The availability and repartition of fucosylated glycans within the gastrointestinal tract contributes to the adaptation of gut bacteria species to ecological niches. To access this source of nutrients, gut bacteria encode α- l -fucosidases (fucosidases)… read more here.

DOI: 10.1016/j.anaerobe.2020.102312

Abstract: Ruminococcus gnavus is a Gram-positive anaerobe and normal gut commensal in the human host. There have been a small number of reported cases of infections attributed to R. gnavus, and no cases of urogenital infections… read more here.

DOI: 10.1038/s41467-025-56449-x

Abstract: Ruminococcus gnavus is a gut bacterium found in > 90% of healthy individuals, but its increased abundance is also associated with chronic inflammatory diseases, particularly Crohn’s disease. Nevertheless, its global distribution and intraspecies genomic variation remain… read more here.

DOI: 10.1053/j.gastro.2017.09.006

Abstract: BACKGROUND & AIMS Dysbiosis of the intestinal microbiota has been associated with development of allergies in infants. However, it is not clear what microbes might contribute to this process. We investigated what microbe(s) might be… read more here.

DOI: 10.1073/pnas.2007595118

Abstract: Significance Microbes shape human health and disease. Today, there are increasing correlations of gut microbes with specific diseases, but the underlying molecules and mechanism linking the two are not known. This stifles both the understanding… read more here.

DOI: 10.1128/mbio.01523-25

Abstract: ABSTRACT A diverse, stable community of microbes in the human gut is strongly tied to health. The factors that regulate microbial community structure and dynamics are ill-defined. In this study, we discover mediterrocin, a bacteriocin… read more here.

DOI: 10.3389/fmicb.2018.01688

Abstract: Ruminococcin A (RumA) is a lanthipeptide with high activity against pathogenic clostridia and is naturally produced by the strict anaerobic bacterium Ruminococcus gnavus E1, isolated from human intestine. Cultivating R. gnavus E1 is challenging, limiting… read more here.
