The composition of your gut microbiome may help protect against the overgrowth of Klebsiella pneumoniae, Escherichia coli and other organisms—and it may be altered by changes in diet (Nat Microbiol 2025 Jan 10. doi:10.1038/s41564-024-01912-6).
Enterobacteriaceae, including K. pneumoniae, E. coli, Shigella and others, are present at low levels as part of the normal gut flora, but whether overgrowth could contribute to bloodstream infections is still unknown.
