Fig. 3From: ESBL-plasmid carriage in E. coli enhances in vitro bacterial competition fitness and serum resistance in some strains of pandemic sequence types without overall fitness costSerum bactericidal activity of triplets of all five strains in 50% a human serum, b chicken serum. IMT209 is used as negative control while IMT5155 as positive control for the assay. p values are represented by asterisk wherever significant as; *p value ≤ 0.05, **p value ≤ 0.01 and ***p value ≤ 0.001Back to article page
