Escherichia coli exhibits sensitive chemotaxis to potassium, mediated by differential responses of Tar and Tsr chemoreceptors to intracellular pH changes induced by potassium concentration gradients.

Gut dysbiosis is involved in severe leptospirosis that is related to translocated microbiota-derived lipopolysaccharide.

Enteric bacteria associated with bloodstream infections are attracted to human serum through L-serine and the chemoreceptor Tsr, and in an enterohemorrhagic lesion model use chemotaxis to invade damaged vasculature.

SARS-CoV-2 infection reduces the intracellular levels of a human tRNA modification enzyme and alters host tRNA modification profiles.

The new vaccine candidate for tuberculosis displays superior protection against disease when compared the currently available vaccine, and can potentially provide new options for global childhood vaccination programs.

N2 neuraminidases from human H3N2 viruses from 2009 until 2017 can be subdivided into four antigenic groups, with amino acid substitutions near the catalytic site more likely impacting neuraminidase inhibition.
