Survival of V. cholerae in mouse intestinal tracts. Infant mice were fed with E. coli Nissle 1917 (Nissle), E. coli Nissle 1917 expressing the V. cholerae autoinducer gene cqsA (Nissle-cqsA), or no bacteria (VC only) before being challenged with V. cholerae. Plate counts determined the cfu of V. cholerae present in the intestines after 16 h and again after 40 h. Values are averages of duplicate mice. Error bars represent 1 SD. The p values are for a Student t test with n = 2.
