(A) Groups of CBA mice were infected intragastrically with a 1:1 mixture of the S. Typhimurium wild type (black circles) and the respiration-deficient napA narZ narG cyxA mutant (blue circles) and samples collected at the indicated days after infection (days p.i.). Dotted red lines connect strains recovered from the same animal. CI, competitive index; ****, P < 0.001; ns, not statistically significantly different; nd, not determined. (B) Groups of CBA mice (N = 4) were infected intragastrically with 1 × 108 CFU/animal of one of the indicated S. Typhimurium strains and samples collected at the indicated days after infection.
