frequency of bla tem, bla shv, bla ctx-m, and qnra among escherichia coli isolated from urinary tract infection
conclusions considering the high prevalence of esbl genes (bla ctx-m, 87%; and bla tem, 82%), fluoroquinolones may be used as an alternative drug in treatment, although resistance to this family is increasing as well. as a result, this increasing trend should be prevented using appropriate guidelines for prescription. background escherichia coli is the most important as well as the most common ...
متن کاملMultiplex PCR for bla(CTX-M) & bla(SHV) in the extended spectrum beta lactamase (ESBL) producing gram-negative isolates.
BACKGROUND & OBJECTIVE Phenotyping is commonly used for detection of extended spectrum beta lactamase (ESBL) production in gram-negative isolates. ESBLs are mainly coded for by three important genes, namely bla(TEM), bla(SHV) and bla(CTX-M). In this study we used a multiplex PCR as a rapid method to identify two common genes (bla(CTX-M) & bla(SHV)) responsible for extended spectrum beta lactama...
متن کاملHigh prevalence of bla(CTX-M) extended spectrum beta-lactamase genes in Klebsiella pneumoniae isolates from a tertiary care hospital: first report of bla(SHV-12), bla(SHV-31), bla(SHV-38), and bla(CTX-M-15) in Brazil.
The aim of this study was to investigate the presence and prevalence of bla(TEM), bla(SHV), and bla(CTX-M) and bla(GES)-like genes, responsible for extended spectrum beta-lactamases (ESBLs) production in clinical isolates of Klebsiella pneumoniae collected from a Brazilian tertiary care hospital. Sixty-five ESBL producing K. pneumoniae isolates, collected between 2005 and 2007, were screened by...
متن کاملOccurrence of OXA-48 Carbapenemase and Other β-Lactamase Genes in ESBL-Producing Multidrug Resistant Escherichia coli from Dogs and Cats in the United States, 2009–2013
OBJECTIVE The aim of this study was to explore the occurrence and molecular characterization of extended-spectrum β-lactamases (ESBL), plasmid-mediated AmpC β-lactamase (pAmpC) and carbapenemases among ESBL-producing multidrug resistant (MDR) Escherichia coli from dogs and cats in the United States. METHODS Of 2443 E.coli isolated from dogs and cats collected between August 2009 and January 2...
متن کاملOccurrence of SHV, TEM and CTX-M β-Lactamase Genes Among Enteropathogenic Escherichia coli Strains Isolated From Children With Diarrhea
BACKGROUND Antibiotic resistance is widespread among diarrheagenic Escherichia coli in developing countries, where the overuse of antibiotics is common. Information regarding β-lactamases, especially Extended-Spectrum β-Lactamases (ESBLs) in diarrheagenic pathogens should be considered in clinical management when an optimal treatment is needed. OBJECTIVES The main objective of this study was ...
