New insights into chemical sensing of the human pathogen for cholera
The bacterium Vibrio cholerae is a serious threat to our health because it is the causative agent of cholera. Worldwide, over a billion people per year are at risk of cholera infection. New strains of V. cholerae are resistant to the multiple drugs used to treat cholera, meaning that new types of drugs…
