Fig. 3From: Pharmacodynamic modelling of in vitro activity of tetracycline against a representative, naturally occurring population of porcine Escherichia coli a Distribution of 50 E. coli strains according to MIC values. b–d Three PD parameters from E max model of 50 E. coli strains according to their MIC values with mean and 95 % confidence interval. The green line represents susceptible isolates and the red line represents resistant isolates. A vertical black line is drawn at cut-off between susceptible and resistant isolatesBack to article page
