  • Values are % (95% CIs) (n).

  • *All isolates of these bacteria tested for susceptibility to this antibiotic were resistant, therefore calculation of CIs was not possible.

  • †No resistant isolates were identified in the studies which performed susceptibility testing on this bacteria for this antibiotic, therefore calculation of CIs was not possible.
