Abstract
The objective of this study was to better understand the in vitro activity of flomoxef against clinical pathogens. A total of 545 clinical isolates, including Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, methicillin-susceptible Staphylococcus aureus (MSSA), methicillin-resistant S. aureus, Streptococcus pneumoniae, and Streptococcus pyogenes, were isolated consecutively from clinical specimens from Peking Union Medical College Hospital in 2013. MICs were determined using broth microdilution method. esbl and ampC genes were detected by polymerase chain reaction and sequencing. Flomoxef showed excellent activity against E. coli, K. pneumoniae, and P. mirabilis isolates, with susceptibility rate of 88.8%, 88.3%, and 97.7%, separately. Moreover, flomoxef exhibited great activity against extended-spectrum beta-lactamase (ESBL) producers, with MIC50/MIC90 of 0.125/(0.5–1) μg/mL. Flomoxef showed MIC50/MIC90 of 0.5/0.5μg/mL against MSSA, 0.125/0.25μg/mL against S. pyogenes, and 2/16μg/mL against S. pneumoniae. In conclusion, flomoxef is one of the cephamycins showing excellent activity against ESBL-producing or ESBL-nonproducing E. coli, K. pneumoniae, and P. mirabilis and was also potent against MSSA, S. pyogenes, and S. pneumoniae.
