Fitness indices of drug resistant strains in the presence of drug susceptible strains from the 3 predominant strain lineages.

The values represent fitness indices of drug resistant strain in the presence of drug susceptible strains from the 3 predominant lineages. The data is represented as a mean ± SD derived from 3 independent experiments. The values represent fitness index on day 14 and have been used to plot Figure 1.Cs1, Cs2, Cs3 are CAS drug susceptible strains.Bs1, Bs2 are Beijing drug susceptible strains.Ms1, Ms2, Ms3 are MANU drug susceptible strains.C-MDR, B-MDR, M-MDR are CAS, Beijing and MANU drug resistant strains respectively.
