Table 2.

Susceptibility and FIC values of two clinical cystic fibrosis isolates of P. aeruginosa isolates tested with manuka honey and either tobramycin or colistin

Antibiotic Pseudomonas aeruginosa reference number Test method MIC (µg/ml) antibiotic FIC antibiotic
Alone With MH
Colistin 867 Broth dilution 0.5 0.25 0.5
E strip 0.38 0.19 0.5
Tobramycin 867 Broth dilution 128 128 1
E strip 32 32 1
Colistin 1099 Broth dilution 16 4 0.25
E strip 0.19 0.125 0.66
Tobramycin 1099 Broth dilution 16 0.5 0.03
E strip 2 0.5 0.25

1 % (w/v) below MIC was used in synergy tests. The FIC values seen were consistent across the methods used
