About the National Data
Baseline: 2.5 percent of domestically-acquired Campylobacter jejuni infections in humans were resistant to macrolides in 2014-16
Target: 2.5 percent
Maintain the baseline
Public health laboratories in 10 FoodNet sites forward a frequency-based sample of Campylobacter isolates that they receive from participating clinical/reference laboratories to NARMS at CDC. CDC scientists test isolates for susceptibility to macrolides and other drug classes using a broth microdilution method and interpret results using criteria from the Clinical and Laboratory Standards Institute (CLSI) when available. Domestically-acquired infections (i.e., no international travel in the 7 days before illness onset) will be identified using travel information available from FoodNet.
