Colistin heteroresistance in carbapenemase-producing Klebsiella pneumoniae.
Sir, Klebsiella pneumoniae is an important pathogen that causes severe and life-threatening infections. Most isolates demonstrate resistance to various antimicrobial agents. Carbapenems have been widely used to treat serious infections with multidrug-resistant K. pneumoniae. However, the increasing use of these compounds has led to the emergence of carbapenem-resistant isolates via acquired gen...
متن کاملEvaluation of Antibiotic Resistance Patterns of Clinical Klebsiella pneumoniae Isolates from Educational Hospitals in Zahedan, Iran
ABSTRACT Background and Objectives: The resistance of gram-negative bacteria to antibiotics has become a serious problem, which imposes a significant increase in treatment costs. Klebsiella pneumoniae is an important nosocomial pathogen from the Enterobacteriaceae family. The aim of this study was to investigate the frequency and pattern of antibiotic resistance in K. pneumoniae strains isolat...
متن کاملHigh Prevalence of CTXM-15 Type Extended-Spectrum Beta-Lactamase Among Clinical Isolates of Klebsiella Pneumoniae
Background: Production of β–lactamases by enterobacteriacea, especially Klebsiella pneumoniae, is one of the emerging health problems in the world. The purpose of this study was to assess the frequency of blaCTX-M15 gene in K. pneumoniae isolates and determine the molecular diversity of CTXM producing isolates. Methods: In...
متن کاملSpread of OXA-48-positive carbapenem-resistant Klebsiella pneumoniae isolates in Istanbul, Turkey.
The first outbreak of carbapenem-resistant Klebsiella pneumoniae isolates producing the plasmid-encoded carbapenem-hydrolyzing oxacillinase OXA-48 is reported. The 39 isolates belonged to two different clones and were collected at the University Hospital of Istanbul, Turkey, from May 2006 to February 2007, and they coproduced various beta-lactamases (SHV-12, OXA-9, and TEM-1 for clone A and CTX...
متن کاملPorin expression in clinical isolates of Klebsiella pneumoniae.
Two porins, OmpK36 and OmpK35, have been described previously in Klebsiella pneumoniae, and they are homologous to the Escherichia coli porins OmpC and OmpF, respectively, at both the DNA and amino acid levels. Optimal resolution of the two K. pneumoniae porins by electrophoresis on polyacrylamide gels is not achieved using gel systems already described for E. coli and requires modifications of...
