Activity of Ceftolozane-Tazobactam and Comparators When Tested against Bacterial Surveillance Isolates Collected from Pediatric Patients in the US during 2012–2016 as Part of a Global Surveillance Program

Activity of Delafloxacin When Tested Against Bacterial Surveillance Isolates Collected in the US and Europe During 2014–2016 as Part of a Global Surveillance Program

Ceftolozane-tazobactam activity against drug-resistant Enterobacteriaceae and Pseudomonas aeruginosa causing healthcare-associated infections in Latin America: report from an antimicrobial surveillance program (2013-2015).

This study evaluated the in vitro activity of ceftolozane-tazobactam and comparator agents tested against Latin American isolates of Enterobacteriaceae and Pseudomonas aeruginosa from patients with health care-associated infections. Ceftolozane-tazobactam is an antipseudomonal cephalosporin combined with a well-established β-lactamase inhibitor. A total of 2415 Gram-negative organisms (537 P. a...

Antimicrobial activity of ceftolozane-tazobactam tested against Enterobacteriaceae and Pseudomonas aeruginosa with various resistance patterns isolated in U.S. Hospitals (2011-2012).

Ceftolozane/tazobactam, a novel antimicrobial agent with activity against Pseudomonas aeruginosa (including drug-resistant strains) and other common Gram-negative pathogens (including most extended-spectrum-β-lactamase [ESBL]-producing Enterobacteriaceae strains), and comparator agents were susceptibility tested by a reference broth microdilution method against 7,071 Enterobacteriaceae and 1,97...

Activity of omadacycline tested against Streptococcus pneumoniae from a global surveillance program (2014).

The activity of omadacycline and comparators when tested against a subset of Streptococcus pneumoniae from US and European regions of a 2014 global surveillance program (304 isolates) are reported. These MIC results were compared to those obtained when testing S. pneumoniae from 2010 surveillance (1,834 isolates). The omadacycline MIC50/90 for S. pneumoniae (2014) was 0.06/0.06μg/mL, similar to...

Surveillance of current antibiotic resistance among clinical isolates S. aureus,E. coli and P. aeroginosa collected from five Iranian cities

Antibiotic resistance is an emerging problem worldwide present in many bacteria, speciallyS. aureus, P. aeroginosa, and E. coli that are consider as the most common group of bacteriaresponsible for nosocomial infections. This problem would be more serious and divesting indeveloping countries where there is not regular surveillance program for periodic antibioticresistance. In attempts to report...
