»The researchers suggest that eating more #fibre in our #diet will support the growth of good #bacteria -- and crowd out the bad ones to significantly reduce the risk of #illness.
In contrast, taking #probiotics -- which don't directly change the environment in the gut -- is less likely to affect the likelihood of #Enterobacteriaceae #infection.«

A new study has found that the composition of your gut microbiome helps predict how likely you are to succumb to potentially life-threatening infection with Klebsiella pneumoniae, E.coli and other bugs -- and it may be altered by changing your diet.
"Lastly, we find that Enterobacteriaceae use human serum as a source of nutrients for growth and that chemotaxis and the chemoreceptor Tsr provides a competitive advantage for migration into enterohaemorrhagic lesions. We term this bacterial behavior of taxis toward serum, colonization of hemorrhagic lesions, and the consumption of #serum nutrients, as “bacterial vampirism” which may relate to the proclivity of #Enterobacteriaceae for bloodstream #infections."
