In vitro activity of tedizolid against Staphylococcus aureus and Streptococcus pneumoniae collected in 2013 and 2014 from sites in Latin American countries, Australia, New Zealand, and China.

Tedizolid is an oxazolidinone with an antimicrobial in vitro potency advantage against Gram-positive bacterial pathogens compared to other currently marketed drugs in this class, including linezolid. Tedizolid was compared to linezolid when tested against Staphylococcus aureus and Streptococcus pneumoniae isolates collected from countries in Latin America and the Asia-Pacific. Isolates were tested by broth microdilution susceptibility methods against tedizolid, linezolid, and non-class comparators in accordance with the Clinical and Laboratory Standards Institute (CLSI) guidelines.

Antimicrobial-resistant Pseudomonas aeruginosa and Acinetobacter baumannii From Patients With Hospital-acquired or Ventilator-associated Pneumonia in Vietnam.

Purpose: Multidrug-resistant bacterial pathogens are becoming a significant problem worldwide. Acinetobacter baumannii and Pseudomonas aeruginosa are problematic multidrug-resistant pathogens. This multicenter study in Vietnam determined the level of resistance to antimicrobial agents used to treat A baumannii and P aeruginosa infections in this country.

Comparative in vitro activities of ceftaroline and ceftriaxone against bacterial pathogens associated with respiratory tract infections: results from the AWARE surveillance study.

Objectives: Ceftaroline fosamil is indicated for the treatment of community-acquired bacterial pneumonia and ceftriaxone has an indication for lower respiratory tract infections. This study was conducted to compare the relative in vitro activities of these two agents against bacterial species associated with community-associated respiratory tract infections.

Methods: In all, 13 005 isolates of Staphylococcus aureus, Streptococcus pneumoniae, Moraxella catarrhalis and Haemophilus influenzae were collected in 2012-14 from 39 countries in the Asia-Pacific region, Europe, Latin America and Africa-Middle East from respiratory tract specimens.

In vitro activity of Ceftaroline against bacterial pathogens isolated from patients with skin and soft tissue and respiratory tract infections in African and Middle Eastern countries: AWARE global surveillance program 2012-2014.

The objective of this report was to document antimicrobial susceptibility testing surveillance data for ceftaroline and comparative agents from the AWARE (Assessing Worldwide Antimicrobial Resistance Evaluation) global surveillance program for bacterial pathogens causing skin and soft tissue and respiratory tract infections in African and Middle Eastern countries from 2012 through 2014. Pathogen identities were confirmed by MALDI-TOF and antimicrobial susceptibility testing performed by CLSI broth microdilution methodology in a central laboratory. All methicillin-susceptible Staphylococcus aureus (MSSA) (n= 923; MIC90, 0.
