Survival of G. mellonella larvae 96 h p.i with increasing inoculum sizes (2.5 × 103, 104, 105 or 106 cfu/mL) of P. aeruginosa NCTC13437 and treated with PBS or dual β-lactam combinations of: (a) MEM + CAZ (2.5 + 5 mg/kg); (b) ATM + CTX (50 + 100 mg/kg); (c) ATM + MEM (50 + 2.5 mg/kg); (d) ATM + PIP (50 + 100 mg/kg). A single dose of the antibiotic treatments was administered 2 h p.i. The uninfected group represents larvae sham-infected with sterile PBS and treated with sterile PBS. Error bars represent the mean ± SEM of replicate experiments.
