Sweet-talk in the time of cholera: host mucin negotiates peace with Vibrio cholerae.

Abstract

Vibrio cholerae, the causative agent of cholera, must first be converted to its toxigenic form and cross the sugar-rich mucus barrier before it can cause disease, but whether these hurdles are linked is unclear. In this issue, Wang etal (2022) provide new evidence that mucus O-glycans directly prevent toxigenic conversion and virulence factor expression in V. cholerae.
