conclusions our study emphasized the increasing role of esbl genes, especially blactx-m15 in epec isolates. results of 42 epec, eight isolates carried the blactx-m1. none of the isolates carried blactx-m2 and blactx-m9. the blactx-m15 variant was identified in all of blactx-m1-positive isolates. furthermore, blashv and blatem genes were detected in 40.5% (n = 17) and 19% (n = 8) of all epec iso...

background infectious diarrhoeal diseases cause major problems throughout the world and are responsible for considerable morbidity and mortality. enteropathogenic escherichia coli (epec) may cause infantile diarrhoea among children in developing countries. objectives the aim of this study was to define the prevalence of epec strains in raw milk samples. materials and methods raw milk samples co...

background and objectives: the therapeutic options for diseases caused by escherichia coli are limited. in this study we investigated the presence of virulence factors among enteropathogenic escherichia coli (epec) strains and their antibiotic resistance patterns. the isolates were also checked for the presence of class1 integrons and gene cassettes. materials and methods: this study included 7...

conclusions this study suggests that epec strains are important contributors to diarrhea in iranian children. because of the weakness of routine microbiological tests and poor specifity of serological tests, it is recommended that the epec strains are better detected by molecular methods. results the e. coli isolates were confirmed by the presence of the uida gene. the epec was diagnosed in 6 c...

OBJECTIVES The aim of this study is to determine the incubation period of enteropathogenic Escherichia coli (EPEC), which creates several outbreaks in a year in South Korea. METHODS We reviewed all water and food-borne outbreaks data reported to the Korea Centers for Disease Control and Prevention (KCDC) from 2009 to 2010 and determined their characteristics. Through this process, we can pres...

objective: the aim of the this study was to investigate the prevalence of toxb, paa, lpf and iha adhesion genes in enteropathogenic escherichia coli (epec) isolates lacking in two important adhesion factors, the eaea and bfpa genes. methods: we examined a total of 70 serologically confirmed epec (eaea-, bfpa-) isolates. dna from the isolates was extracted by the phenol-chloroform method. toxb,...
