For example, the absence of commensal bacteria
was found to have a systemic effect on T- and B-cell zones in spleens and secondary lymphoid organs.[sup] And germ-free mice have fewer germinal centers, plasma cells, and Igs systemically.
The work will investigate the association between the host model Drosophila melanogaster and one of its most abundant commensal bacteria
, Lactobacillus plantarum, which was demonstrated to be beneficial to its host physiology by promoting juvenile growth and maturation.
can alter virulence of bacterial pathogens and interfere with antibiotic treatment.
RNA sequencing identified commensal bacteria
in all samples, but C.
The most commensal bacteria
present in human fecal flora are represented by two main groups of Firmicutes, subdivided in Clostridium coccoides (Clostridium cluster XIVa) and Clostridium leptum (Clostridium cluster IV) that are butyrate producers, and by the group of the Cytophaga-Flavobacterium-Bacteroides (CFB) [3, 4].
The differences are believed to help commensal bacteria
by providing specific binding sites, as well as necessary nourishment.
Although immune cells in the skin protect against harmful organisms, until now, it has not been known if the millions of naturally occurring commensal bacteria
in the skin - collectively known as the skin microbiota - also have a beneficial role.
Background & objectives: The intestinal epithelium is part of the innate immune system responding to contact with pathogenic or commensal bacteria
. The objective of this study was to compare innate responses of intestinal epithelial cell lines to pathogenic bacteria and to lactobacilli.
Harvey's approach involves colonizing young pigs' intestinal tracts with a mixture of commensal bacteria
, obtained from other pigs, that help establish a healthy gut flora much more quickly than would otherwise occur.
IBD is believed to result from interactions between genetic factors and environmental triggers, such as commensal bacteria
with pathogenic potential.
We can't assume that commensal bacteria
residing on skin of healthy individuals is going to be therapeutic in individuals with impaired skin immune function and disease.
The outer mucus layer contains a large number of microbes and appears to be an amenable habitat for commensal bacteria
. However, the inner adherent mucus layer contains a very low number of microbes and forms a protective zone adjacent to the epithelial surface .
