Fig 2. MIC distribution and polymyxin B resistance in carbapenem-resistant Klebsiella pneumoniae, January 2010—December 2019.

Fig 2

Minimum inhibitory concentrations distribution and proportion of polymyxin B resistance among carbapenem-resistant Klebsiella pneumoniae isolates from January 2010 to December 2019. (A) Absolute number of samples distributed according to the minimum inhibitory concentrations obtained by broth microdilution of 45 carbapenem-resistant Klebsiella pneumoniae isolates. Susceptibility (light grey), resistance (dark grey). (B) Percentages of susceptible (light grey) and resistant (dark grey) polymyxin B isolates amidst 65 episodes of carbapenem-resistant Klebsiella pneumoniae bloodstream infections, yearly stratified. Notes: CRKp—carbapenem-resistant Klebsiella pneumonia; MIC–Minimum inhibitory concentration.
