OBJECTIVE: To evaluate the potency and spectrum of ceftaroline and comparator agents tested against contemporary bacteria isolated from patients with community-acquired bacterial pneumonia (CABP) in Europe (EUR), Asia-Pacific (APAC), and Latin America (LATAM). METHODS: A total of 4321 bacterial isolates were collected consecutively by the SENTRY Antimicrobial Surveillance Program in 2015-2017 from 65 medical centers located in Western Europe (W-EUR; 21 centers in 10 nations), Eastern Europe and the Mediterranean region (E-EUR; 15 centers in 11 nations), APAC (18 centers in nine nations), and LATAM (11 centers in nine nations). Isolates were collected from lower respiratory tract specimens, and an isolate obtained from an outpatient or earlier than 48h after hospitalization was considered community-acquired. Organisms were tested for susceptibility by reference broth microdilution methods in a central laboratory. RESULTS: Among Streptococcus pneumoniae (n=1736), 99.9% of isolates were ceftaroline-susceptible (MIC50/90, 0.008/0.12mg/l), and ceftriaxone susceptibility (≤1mg/l) ranged from 97.4% in W-EUR to 85.3% in the APAC region. Ceftaroline was also active against Haemophilus influenzae (n=1172; MIC50/90, 0.008/0.03mg/l; 99.8%/93.9% susceptible per CLSI/EUCAST criteria) and Staphylococcus aureus (n=777; MIC50/90, 0.25/1mg/l; 97.4% susceptible). Oxacillin resistance ranged from 31.9% in the APAC region to 15.0% in E-EUR. Ceftaroline also demonstrated potent activity against Moraxella catarrhalis (n=613; MIC50/90, 0.06/0.25mg/l) and Haemophilus parainfluenzae (n=23; MIC50/90, 0.015/0.03mg/l). CONCLUSIONS: Susceptibility rates varied widely by geographic region. Ceftaroline was active against the vast majority of bacterial organisms isolated from patients with CABP.
