Cell dish experiments showed that L. lactis had an antibacterial effect when grown on a layer of cholera bacteria. A strain of L. lactis deficient in lactic acid production (L. lactis Δldh) did not show the same effect. This material relates to a paper that appeared in the 13 June, issue of Science Translational Medicine, published by AAAS. The paper, by N. Mao at Massachusetts Institute of Technology in Cambridge, MA; and colleagues was titled, "Probiotic strains detect and suppress cholera in mice."
