Figure HKW-2. Rates of macrolide resistance for streptococci by age groups, 2017-2021
- The susceptibility data for the following number of isolates were analyzed: S.pyogenes (471), S. agalactiae (4626), Group G streptococci (989) and S.pneumoniae (429).
- Non-duplicate isolates from all specimens.
- Nonsusceptible include both intermediate and resistant. Erythromycin was tested and used as an indicator for resistance to macrolides (e.g. clarithromycin, azithromycin)
