Characterization of Carbapenem-Resistant Enterobacteriaceae Clinical Isolates in Al Thawra University Hospital, Sana'a, Yemen
International audience; Objective: The aim of this study was to investigate the resistance mechanisms of carbapenem-resistant Enterobacteriaceae clinical strains recovered from Al Thawra University Hospital, Sana'a, Yemen. Methods: A total of 27 isolates showing decreased susceptibility to carbapenems were obtained from different clinical specimens in Al Thawra Hospital, Sana'a, Yemen. Strains were identified by Matrix Assisted Laser Desorption Ionization Time-Of-Flight spectroscopy. Susceptibility to antibiotics was determined by the disk diffusion method on Mueller Hinton agar. Carbapenemases-encoding genes, extended-spectrum β-lactamases (ESBLs), and plasmid-mediated quinolone resistance…
Spread of Klebsiella pneumoniae ST395 non-susceptible to carbapenems and resistant to fluoroquinolones in North-Eastern France
Abstract Objectives Fluoroquinolones (FQs) are a potential treatment for infections caused by extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae that are susceptible to these agents. Methods Owing to increasing non-susceptibility to carbapenems among Enterobacteriaceae, in this study FQ resistance mechanisms were characterised in 36 ertapenem-non-susceptible Klebsiella pneumoniae isolated from North-Eastern France in 2012. The population structure was described by pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). Results Among the 36 isolates, 13 (36%) carried a carbapenemase encoding-gene. Decreased expression of the OmpK35-encoding gene might be…
