Bacterial counts at D6-PI in kidneys of mice infected by strains with different temocillin MICs (Ec8, 8 mg/L; Ec16, 16 mg/L; Ec32, 32 mg/L; Ec64, 64 mg/L) in control and treated groups. Each circle represents one mouse. Filled black circles, controls; grey circles, mice treated with a regimen simulating temocillin at 2 g q12h; white circles, mice treated with a regimen simulating temocillin at 2 g q8h. The black line represents the median. *P < 0.001 between groups.
