Survival of Salmonella in mice (squares, geometric mean ± geometric s.d.; enrofloxacin: Slc11a1 s /WT, n = 10; Slc11a1 s / hipA D88N , n = 4; Slc11a1 r /WT, n = 8; ceftriaxone, n = 6), or in chemostats in tissue-mimicking medium (geometric mean ± geometric s.d.; enrofloxacin for division rates 0.083 h −1 , 0.17 h −1 and 0.33 h −1 , n = 10; ceftriaxone, n = 4), Mueller–Hinton broth (enrofloxacin or ceftriaxone for division rates 0.083 h −1 , 0.17 h −1 and 0.33 h −1 , n = 5) or in individual batch cultures (enrofloxacin: tissue-mimicking medium, n = 3; Mueller–Hinton broth, n = 5; ceftriaxone: tissue-mimicking medium and Mueller–Hinton broth, n = 3). One-way ANOVA with test for linear trend for log-transformed data for tissue-mimicking medium or Mueller–Hinton broth cultures.
