To investigate the dissemination of ESBL/pAmpC-producing E. coli within the food distribution system of Ho Chi Minh City (HCMC), Vietnam, the prevalence of ESBL/pAmpC-producing E. coli strains in chicken meat, pork, beef, and fish/shrimp samples obtained from slaughterhouses, a wholesale market, and supermarkets was examined. Among the total of 330 collected food samples, ESBL/pAmpC-producing E...

background and objectives: the most common serotype of enterohaemorrhagic esherichia coli group or shiga-toxin-producing e. coli is o157:h7. domestic and wild ruminants are regarded as the main natural reservoirs. o157:h7 serotype is the major cause of gastrointestinal infections in developed countries. in this study was conducted to survey on the toxigenic e. coli o157: h7 strains in milk of i...

An NDM-1 carbapenemase-producing Escherichia coli isolate of sequence type 131 (ST131) that belonged to phylogenetic group B2 was obtained from a patient with a urinary tract infection who returned to the United States after a recent hospitalization while visiting India. NDM-1-producing E. coli ST131 had significantly more virulence factors than NDM-1-producing E. coli ST101, previously isolate...

BACKGROUND Widespread prevalence of extended-spectrum βeta-lactamase producing Escherichia coli (ESBL-producing E. coli) limits the infection therapeutic options and is a growing global health problem. In this study our aim was to investigate the antimicrobial resistance profile of the E. coli in hospitalized and out-patients in Cyprus. RESULTS During the period 2010-2014, 389 strains of E. c...

BACKGROUND Escherichia coli is an important bacterial species based on incidence and associated infection severity. Some E. coli strains produce extended-spectrum beta lactamase (ESBL) and are called ESBL-producing E. coli. These strains are resistant to most classes of cephalosporin and a number of other classes of antibiotics. Plasmids carrying qnr genes have been found to transmit quinolone ...

background escherichia coli (e. coli) species are able to produce extended-spectrum β-lactamases (esbls) that cause high resistance to the beta-lactam antibiotics. therefore, determining the antibiotic susceptibility patterns in resistant organisms is necessary for suitable therapeutic approaches. patients and methods totally, 260 clinical isolates of e. coli were collected from hospitals in te...

BACKGROUND A large outbreak of diarrhea and the hemolytic-uremic syndrome caused by an unusual serotype of Shiga-toxin-producing Escherichia coli (O104:H4) began in Germany in May 2011. As of July 22, a large number of cases of diarrhea caused by Shiga-toxin-producing E. coli have been reported--3167 without the hemolytic-uremic syndrome (16 deaths) and 908 with the hemolytic-uremic syndrome (3...

Some Escherichia coli strains produce toxins designated cyclomodulins (CMs) which interfere with the eukaryotic cell cycle of host cells, suggesting a possible link between these bacteria and cancers. There are relatively few data available concerning the colonization of colon tumors by cyclomodulin- and genotoxic-producing E. coli. We did a qualitative and phylogenetic analysis of mucosa-assoc...

Escherichia coli remains as one of the most important bacteria causing infections in pediatrics and producing extended-spectrum beta-lactamases (ESBLs) making them resistant to beta-lactam antibiotics. In this study we aimed to genotype ESBL-producing E. coli isolates from pediatric patients for ESBL genes and determine their association with antimicrobial resistance. One hundred of the E. coli...
