ABSTRACTOmadacycline was tested against 21,000 bacterial isolates collected prospectively from medical centers in Europe and the United States during 2016. Omadacycline was active againstStaphylococcus aureus(MIC50/MIC90, 0.12/0.25 mg/liter), including methicillin-resistantS. aureus(MRSA); streptococci (MIC50/MIC90, 0.06/0.12 mg/liter), includingStreptococcus pneumoniae, viridans group streptococci, and beta-hemolytic streptococci;Enterobacteriaceae, includingEscherichia coli(MIC50/MIC90, 0.5/2 mg/liter);Haemophilus influenzae(MIC50/MIC90, 1/1 mg/liter); andMoraxella catarrhalis(MIC50/MIC90, 0.25/0.25 mg/liter). Omadacycline merits further study in serious infections where resistant pathogens may be encountered.

Abstract Background The SENTRY Antimicrobial Surveillance Program monitors the frequency of occurrence and antimicrobial susceptibility of organisms from various infection types worldwide. In this investigation, we evaluated the antimicrobial susceptibility of Streptococcus pneumoniae isolates collected worldwide over 20 years (1997–2016). Methods A total of 65 993 isolates were consecutively collected (1 per infection episode) from North America (NA; n = 34 626; 2 nations), Europe (EUR; n = 19 123; 23 nations), the Asia-Pacific region (APAC; n = 7111; 10 nations), and Latin America (LATAM; n = 5133; 7 nations) and tested for susceptibility using reference broth microdilution methods. Resistant subgroups included multidrug-resistant (MDR; nonsusceptible to ≥3 classes of agents) and extensively drug-resistant (XDR; nonsusceptible to ≥5 classes). Results The isolates were collected primarily from respiratory tract infections (77.3%), and 25.4% were from pediatric patients. Penicillin susceptibility (≤0.06 mg/L) rates varied from 70.7% in EUR to 52.4% in APAC for all years combined. In NA, there was a slight improvement in susceptibility for the first few years of the program, from 66.5% in 1997–1998 to 69.4% in 1999–2000, followed by a decline until 2011–2012 (57.0%). Similar declines in penicillin susceptibility rates were observed in all regions, with the lowest rates of 67.3% in EUR (2011–2012), 41.6% in the APAC region (2007–2008), and 48.2% in LATAM (2013–2014). These declines were followed by improved susceptibility rates in all regions in later program years, with susceptibility rates of 55.6% to 71.8% in 2015–2016 (65.8% overall). Susceptibility rates to ceftriaxone, erythromycin, clindamycin, tetracycline, and trimethoprim-sulfamethoxazole followed a similar pattern, with a decrease in the first 12–14 years and a continued increase in the last 6–8 years of the program. MDR and XDR frequencies were highest in APAC (49.8% and 17.3% overall, respectively) and lowest in LATAM (10.8% and 1.9% overall, respectively). The most active agents for MDR/XDR isolates were ceftaroline (99.7%/99.1% susceptible), tigecycline (96.8%/95.9% susceptible), linezolid (100.0%/100.0% susceptible), and vancomycin (100.0%/100.0% susceptible). Conclusions S. pneumoniae susceptibility to many antibiotics increased in all regions in the last few years, and these increases may be related to PCV13 immunization, which was introduced in 2010.

ABSTRACT As part of the CANCER Antimicrobial Surveillance Program in North America, a Pseudomonas aeruginosa isolate, strain 07-406, was shown to possess a metallo-β-lactamase, designated VIM-7. bla VIM-7 is located on a 24-kb plasmid which can be readily transferred into Enterobacteriaceae and other pseudomonads. This is the first report of a mobile metallo-β-lactamase gene, bla VIM-7, being detected within the United States.

ABSTRACTTotals of 8.7% (103/1,190) and 21.0% (249/1,190) of theStreptococcus pneumoniaeisolates recovered from specimens collected in the United States during the 2011-2012 AWARE (AssessingWorldwideAntimicrobialResistanceEvaluation) Surveillance Program were ceftriaxone nonsusceptible according to the CLSI (≤1 μg/ml for susceptible) and EUCAST (≤0.5 μg/ml for susceptible) criteria, respectively. Decreased susceptibility to ceftriaxone (MIC, 1 μg/ml) was frequently observed among serotypes 19A (51.4%; 128/249) and 35B (29.7%; 74/249), which were most often observed in the East South Central and South Atlantic U.S. Census regions. Ceftaroline (MIC50/90, 0.12/0.25 μg/ml) remained active (≥96.8% susceptible) when tested against these less susceptible isolates.
