PMN induced growth inhibition of ESBL- and non-ESBL-producing E. coli . Growth of MG1655 and CFT073 incubated with PMN (MOI 10) or without PMN (A). Relative growth inhibition of MG1655, CFT073 and the mean relative growth inhibition of susceptible and ESBL-producing E. coli. The relative growth inhibition (delta OD620) is calculated as (absorbance of bacteria-(absorbance of bacteria + PMN)) (B). Data are presented as mean ± SEM (n = 3 independent experiments). Asterisks denote statistical significance (*p < 0.05).
