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...

The pathogenicity of classical enteropathogenic Escherichia coli strains of human origin was investigated in gnotobiotic piglets. One to two day old piglets in groups of four were infected perorally with approximately 10(8) colony forming units of one of eight enteropathogenic E coli strains or a non-pathogenic control strain. Animals were necropsied 24 or 48 hours after infection and their int...

in this study, it has been our purpose to isolate and serotype enteropathogenic e. coli, salmonella and shigella and determine their resistance to antibiotics. 502 swab specimens were collected during mid-july to midnovember. 1986. from two children's hospitals in tenran. from 502 cultured specimens. 108 specimens were positive for salmonella. shigella and enteropathogenic e. coli. corresp...

Background: It is well known that the herbs have therapeutic efficacy against infectious agents including bacterial ones. In current study, antibacterial activities of methanolic extracts nine were evaluated resistant enteropathogenic E. coli (EPEC) using disc diffusion method. Methods: Isolation and identification EPEC was done by standard bacteriological methods PCR assays. Sensitivity isolat...

the role of enterotoxigenic e.coli as a causative agent in diarrheal disease was studied among 100 cases of infant and children 0-2 years of age. routine bacteriological methods were used for identification enteropathogenic e.coli, salmonella, shigella and vibrio cholera. the ability of e.coli strains to produce toxin was assayed in animal models (rebbit-ileal loop and suckling mice) and in tis...

background: integrons are the major reasons of multidrug resistance (mdr) among enteropathogenic bacteria. occurrence of horizontal gene transfer between integron-carrying microorganisms and other enteric bacteria may increase the rate of emergence of integron-associated antibiotic resistance. objectives: the objective of this study was to investigate class 1 integrons among members of enteropa...

Between October 2007 and March 2008, 153 wild boars shot in the Canton of Geneva in Switzerland were sampled. Fifty-one percent of the animals were males and 49% were females. The age of most (81%) animals varied between 6months and 2years. Prevalence of enteropathogenic Yersinia in tonsils and faeces was studied using culture and PCR methods and in tissue fluid of tonsils using an ELISA system...

The characterization of nine atypical enteropathogenic Escherichia coli strains expressing localized adherence in HeLa cells in the absence of the bundle-forming pilus revealed a diversity of serotypes, plasmids, and virulence genes. Although the strains lacked known E. coli adhesin genes, the identification of new adhesins could contribute to the characterization of similar enteropathogenic E....
