Multidrug resistant (MDR) Klebsiella pneumoniae is a common cause of nosocomial infections worldwide. Recent years have seen an explosion of resistance to extended-spectrum β-lactamases (ESBLs) and emergence of carbapenem resistance. Here, we examine 198 invasive K. pneumoniae isolates collected from over a decade in Kilifi County Hospital (KCH) in Kenya. We observe a significant increase in MD...
Extended-spectrum β-lactamases (ESBLs) and AmpC β-lactamases produced by a clinical isolate of Klebsiella pneumoniae from chickens were detected with confirmatory phenotypic tests of the Clinical and Laboratory Standards Institute. The minimum inhibitory concentrations of 18 antibacterial drugs against K. pneumoniae were determined by the 2-fold microdilution method. The genotype and sub...
OBJECTIVES To enumerate and characterize extended-spectrum beta-lactamases (ESBLs) amongst ceftriaxone-resistant coliforms in Blantyre, Malawi, where third-generation cephalosporin use is currently highly restricted. METHODS Over the period April 2004-March 2005 all ceftriaxone-resistant isolates from blood cultures were examined for the presence of ESBLs. Isoelectric focusing was performed o...
Extended-spectrum β-lactamases (ESBLs) are rapidly evolving group of β-lactamase enzymes produced by the Gram negative bacteria. In this study, we determined the antimicrobial sensitivity pattern of Escherichia coli isolates and prevalence of TEM, SHV and CTX-M genes in ESBL positive E. coli isolated from the patients admitted to a tertiary care hospital in North-East India. A total of 85 multi...
Abstract Multidrug resistance is one of the worldwide public health concerns. Water represents most suitable environment, for exchange antibiotic genes among pathogenic to non-pathogenic bacteria. Therefore, we aimed screen presence bla NDM-1 , TEM SHV CTX-M and mcr1–5 water samples from different locations Lower Himachal Pradesh. We examined genotypic incidences CTXM by polymerase chain reacti...
in modern medical processes, new antimicrobial drugs are being widely used in order to rapid and essential eradication of resistant bacterial strains. broad-spectrum beta-lactamases are enzymes originated from mutations in the common plasmid genes mediators for beta-lactamases such as tem-1, tem-2, and shv-1 are transferred among bacterial species. the genes coding the production of esbl are of...
background and objective: nowadays, the presence of extended-spectrum β-lactamases (esbls) producing strains in serratia genus causes the emergence of resistance to many antibiotics. so, the lack of proper diagnosis of esbls strains can lead to failure in the treatment. the objective of the present study was to investigate esbls production in serratia strains isolated from the clinical blood sa...
knowledge of antimicrobial resistance patterns in e. coli, the predominant pathogen associated with urinary tract infections (uti) is important as a guide in selecting empirical antimicrobial therapy. methods: to describe the antimicrobial susceptibility of e. coli associated with uti in a major university hospital in tehran (iran), seventy-six clinical isolates of e. coli were studied for susc...
