Additional parameter values associated with the effects of antibiotics

Antibiotic (ciprofloxacin) parameter Value How calculated
κkill, maximum antibiotic killing rate 18.5 h−1 Fitting an Emax model to antibiotic kill curves (18)
EC50, concentration of antibiotic at which the killing rate is half its
maximum
0.3697 μg/ml Calculated using the MIC of ciprofloxacin for the
phage-resistant PAPS strain (7)
ECBP, concentration of antibiotic at which the killing rate is half its
maximum
4.070 μg/ml Calculated using the MIC of ciprofloxacin for the
phage-sensitive PAPS strain (7)
H, Hill coefficient 1 From reference 18
MIC of ciprofloxacin for P. aeruginosa PAPS phage-resistant strain 0.014 μg/ml From reference 7
MIC of ciprofloxacin for P. aeruginosa PAPS phage-sensitive strain 0.172 μg/ml From reference 7
θ, antibiotic elimination rate from serum samples 0.53 h−1 Estimated from antibiotic concentration-vs-time curves;
concentration of ciprofloxacin was measured in serum
samples of P. aeruginosa-infected mice (38)
Antibiotic-sensitive bacterial parameters
    *μ1, probability of emergence of antibiotic-sensitive (phage-resistant)
mutants per cellular division
2.85 × 10−8 Estimated from experimental measurements (39)
    μ2, probability of emergence of phage-sensitive (antibiotic-resistant)
mutants per cellular division
2.85 × 10−8 Approximated to the estimates from reference 39
    rA, maximum growth rate of antibiotic-sensitive (phage-resistant)
bacteria
0.675 h−1 10% tradeoff between resistance against phage and
growth rate (43)
