Carbapenem resistance trends among multiple organisms in India, 2008–2014 (error bars indicate the 95% confidence interval). For E. coli and K. pneumoniae, data are presented only from 2011, as the minimum inhibitory concentration (MIC) values were lowered in June 2010. For P. aeruginosa, data are presented from 2012, as MIC values were lowered in January 2012. For Acinetobacter species, MIC values were lowered in January 2014, and thus there is a possibility that resistance for the years 2008–2013 is underestimated.
