is one of the most important opportunistic pathogens causing serious complications. In recent
years the prevalence of resistance to antibiotics has raised serious concern. Resistance to carbapenems is mainly caused
by the OXA type enzymes; however resistance to cephalosporines are caused by chromosomal AmpC or by extended spectrum
beta-lactamases, such as PER. The group investigated the epidemiology of PER-like enzymes among the clinical A. baumannii
recovered in a governmental secondary hospital in Kuwait from July 2011-August 2012. One hundred and ten non-duplicate
isolates were collected from the clinical microbiology laboratory. Antibiotic susceptibility testing was performed
by Vitek2 and examined according to the CLSI guidelines.
B multiplex PCR was performed to identify
PCR was used to amplify and sequences
(OXA-types) carbapenemases, insertion elements,
(IMP). PFGE was used to genotype the isolates.
(OXA-23) was identified in 28
(OXA-24) in 6, GES-type in 1 and PER-like in 6 isolates. PFGE analysis revealed 12 different pulsed-field types of
All strains containing the PER-7 like enzyme contained OXA-23 and belonged to two different PFGE types. Two point mutations
on the Ω-loop of the PER-7 protein were detected which may be significant in increasing resistance. These point mutations
may be caused when cephalosporins were administered to the patients prior to colistin. The PER-7 gene has been shown to be
located on multi-resistance plasmids; therefore in order to monitor and to control the spread of horizontal transfer of resistance;
genotyping studies are essential.
