¿Se debe revisar la determinación de la CIM de colistín en Acinetobacter baumannii?

Rev. chil. infectol; 34 (4), 2017
Currently, there is a controversy in how to determine the minimal inhibitory concentration (MIC) of colistin against Acinetobacter baumannii. We compared three methods, concluding that the addition of Tween-80 (0.002%) to Müller-Hinton broth in the microdilution method could improve MIC determination an...
