Abstract

To investigate antimicrobial resistance among pathogens responsible for adult community-acquired respiratory tract infections from 11 hospitals of China. From January to December 2012, a total of 599 strains causing adult community-acquired respiratory tract infection were collected from 11 hospitals, including 381 Streptococcus pneumonia, 137 Haemophilus influenza, and 81 Moraxella catarrhalis. The minimal inhibitory concentration (MIC) of antibacterial agents was determined by agar dilution method. Of all the strains, 50% (300/599 strains) were from adults more than 60 years old and only 16.2% (97/599 strains) were from patients aged less than 40 years. According to oral penicillin breakpoints, 56.7% (216/381 strains) of Streptococcus pneumoniae were penicillin non-susceptible strains (PNSSP). More than 90% (345/381 strains) and 39.9% (152/381 strains)-50.7% (193/381 strains) of Streptococcus pneumoniae were resistant to macrolides and oral cephalosporins respectively, but over 97.8% (372/381 strains) and 99% (377/381 strains) were susceptible to levofloxacin and moxifloxacin. PNSSP strains exhibited significant higher resistance to ceftriaxone, amoxicillin/clavulanate, cefaclor and cefuroxime compared with penicillin suscept...Continue Reading
