aBreakpoints according to The European Committee on Antimicrobial Susceptibility Testing. (EUCAST (http://www.eucast.org webcite; Clinical breakpoints v2.0)).

bβ-lactamase was produced by 34 (52%) of the examined isolates, and all these isolates were considered as resistant to penicillin G independent on their MIC values.

cBecause of the lack of EUCAST breakpoints, the EUCAST breakpoints for azithromycin were used also for erythromycin.

MIC, minimum inhibitory concentration.
