All isolates (n = 100) | South Asian clade (n = 47) | African clade (n = 11) | South American clade (n = 39) | East Asian clade (n = 3) | |
Range | 0.03–8 | 0.125–8 | 0.03–1 | 0.03–0.5 | 0.06–0.25 |

MIC90 | 1 | 8 | 0.5 | 0.25 | 0.25 |
MICs were read visually after 24 h of incubation at 35°C as the lowest concentration that inhibited 50% of growth compared to the growth control.
