Fig. 1

Phages were combined with antibiotics to remove different planktonic Shigella. a Shigella 1.1869 were removed by phage SSE1 and antibiotics, b Shigella 1.1868 were removed by phage SGF2 and antibiotics, c Shigella 1.10599 were removed by phage SGF3 and antibiotics. Gray represents negative control without phage and antibiotics, green represents phage SSE1 and its antibiotic combinations, yellow represents phage SGF2 and its antibiotic combinations, orange represents phage SGF3 and its antibiotic combinations, and blue represents antibiotic alone. Groups 1, 2, 3, 4, 5, 6, 7, 8, and 9 correspond to erythromycin, gentamicin sulphate, chloramphenicol, cefotaxime, cefoxitin, cephalothin, cardelmycin, tetracycline hydrochloride, and polymyxin B sulphate, respectively. The concentration of all the antibiotics used was 1/2 MIC. Error bars represent standard deviation of three biological replicates. The letters a, b, c, d, e, f, g, and h indicate significant results; the significance level was set at p < 0.05
