Antibiotic susceptibilities were determined according to NCCLS criteria 47% of S. pneumoniae were penicillin-nonsusceptible: 25% intermediate (MIC 0.12–1 g/ml), and 22% resistant (MIC 2 g/ml) 30% of S. pneumoniae were AZM-nonsusceptible (MIC 5 g/ml); of these, 82% were clindamycin-susceptible Rates of -lactamase production among H. influenzae and M. catarrhalis were 55% and 100%, respectively; all H. influenzae and S. pyogenes isolates were susceptible to AZM and A/C LOOK FOR THE PCR %
