Characterization of CTX-M-Type Extend-Spectrum β-Lactamase Producing Klebsiella spp. in Kashan, Iran
CONTEXT The CTX-M family consists of more than 50 β-lactamases, which are grouped on the basis of sequences into five subtypes including CTX-M-1, CTX-M-2, CTX-M-8, CTX-M-9 and CTX-M-25. OBJECTIVES The current study aimed to detect subtypes of CTX-M extended-spectrum β-lactamases (ESBLs) among ESBL positive Klebsiella isolates from patients in Kashan, Iran. MATERIALS AND METHODS A total of 1...
متن کاملcharacterization of ctx-m-type extend-spectrum β-lactamase producing klebsiella spp. in kashan, iran
results of the 100 klebsiella isolates, 41 (41%) demonstrated resistance or reduced susceptibility to ceftazidime and/or aztreonam and 35% (n = 35) were esbl-producers. twenty-eight (8o%) of the esbl-producing isolates carried the blactx-m type genes. based on pcr assays and sequencing of blactx-m genes, ctx-m-1, ctx-m-2 and ctx-m-9 were identified in 21 (60%), 15 (42%) and nine (34%) of these ...
متن کاملCTX-M extended-spectrum β-lactamase-producing Klebsiella spp, Salmonella spp, Shigella spp and Escherichia coli isolates in Iranian hospitals
This study was conducted in Iran in order to assess the distribution of CTX-M type ESBLs producing Enterobacteriaceae. From January 2012 to December 2013, totally 198 E. coli, 139 Klebsiella spp, 54 Salmonella spp and 52 Shigella spp from seven hospitals of six provinces in Iran were screened for resistance to extended-spectrum cephalosporins. After identification and susceptibility testing, is...
متن کاملCTX-M-Type Extended-Spectrum β-Lactamase-Producing Klebsiella pneumoniae Isolated from Cases of Bovine Mastitis in Japan
Three Klebsiella pneumoniae isolates producing extended-spectrum beta-lactamase (ESBL) were obtained from three dairy cows with clinical mastitis in two farms in western Japan. Two of the 3 isolates from cows in different farms were able to transfer plasmids carrying the blaCTX-M-2 gene to Escherichia coli recipient. Pulsed-field gel electrophoresis (PFGE) patterns of the 2 isolates were differ...
متن کاملPrevalence of CTX-M-Type and PER Extended-Spectrum β-Lactamases Among Klebsiella spp. Isolated From Clinical Specimens in the Teaching Hospital of Kashan, Iran
BACKGROUND Extended-spectrum β-lactamases (ESBLs) is one of the most important mechanisms of resistance to β-lactams especially among Enterobacteriaceae family including Klebsiella spp. Different types of extended-spectrum β-lactamases including CTX-M-type and PER enzymes are identified among gram negative bacteria. OBJECTIVES The current study aimed to determine the prevalence of CTX-M-type ...
