Introduction: Even though the increasing incidence of VIM-producing and has been reported worldwide, studies are still lacking in Palestine. The aim of this study was to screen carbapenem-resistant and bacteria in the Gaza Strip, Palestine and further to characterize carbapenemase-producing isolates.
Methods: A total of 69 and 27 isolates were obtained from three Gaza hospitals and recovered from urine, wound swabs, blood and ear discharge. The screening for metallo-β-lactamases (MBLs) was performed by using the imipenem-EDTA disc synergy test. The detection of β-lactamases genes, detection of non-β-lactam genes and the characterization of integrons were performed by PCR and sequencing. The clonal relationship among the isolates was determined by pulsed-field gel electrophoresis (PFGE).
Results: Our study showed that 4 (5.8%) and 5 (18.5%) were positive by the imipenem-EDTA disc synergy test. was detected in six isolates and was identified in three isolates. The β-lactamases genes in the VIM-producing isolates were (n=3), (n=1), (n=3), (n=1), (n=1) and (n=1). -Ib-cr gene was confirmed in four and in two isolates. was identified in two isolates. The class 1 integron was identified with the different gene cassette; and were identified.
Conclusions: Our study indicated for the first time the emergence of multidrug-resistant VIM-containing and isolates of clinical origin in Gaza Strip hospitals.
