Multi-Locus Sequence Typing of Enteroaggregative Escherichia coli Isolates from Nigerian Children Uncovers Multiple Lineages
BACKGROUND Enteroaggregative Escherichia coli (EAEC) are defined by their stacked-brick adherence pattern to human epithelial cells. There is no all-encompassing genetic marker for EAEC. The category is commonly implicated in diarrhea but research is hampered by perplexing heterogeneity. METHODOLOGY/PRINCIPAL FINDINGS To identify key EAEC lineages, we applied multilocus sequence typing to 126...
متن کاملCharacterization co-existence of ESBLs, AmpC and MBLs in Escherichia coli and Klebsiella pneumoniae isolates from Khorramabad Hospitals
Background: Prevalence of co-existence of extended-spectrum β-lactamases (ESBLs), metallo-beta-lactamase (MBLs) and AmpC-β-lactamases producing isolates in these bacteria is a serious problem in treatment of infections. The aim of this study was to characterization co-existence of ESBLs, AmpC and MBLs in Escherichia coli and Klebsiella pneumoniae isolates from Khorramabad hospitals. Materials ...
متن کاملmultiplex pcr study of plasmid-mediated ampc beta-lactamase genes in clinical isolates of escherichia coli
background : ampc β-lactamases are important cephalosporinases chromosomally encoded in many of enterobacteriaceae and a few other organisms where they mediate resistance to cephalothin, cefazolin, cefoxitin and penicillins. the six different families of plasmid-mediated ampc β-lactamases have been described, but no phenotypic test can discriminate among them. ampc multiplex pcr has been succ...

assessment of ampc beta-lactamase genes among clinical escherichia coli isolates
background : ampc beta lactamases play a significant role in creating resistance to third generation cephalosporins worldwide. they mostly express on chromosome of enterobacteriaceae especially escherichia coli and cause consequential problem in clinical treatment and lead to failure in diagnosis and phenotypic test recommended by clinical and laboratory standards institute. methods : total...
