Prevalence and characteristics of the O122 pathogenicity island in typical and atypical enteropathogenic Escherichia coli strains.
نویسندگان
چکیده
The presence of the pathogenicity island (PAI) O122 genes, efa1 (lifA), sen, pagC, nleB, and nleE, in typical and atypical enteropathogenic Escherichia coli (EPEC) strains was investigated. The simultaneous occurrence of all genes was statistically associated with diarrhea due to atypical EPEC. Detection of the complete PAI O122 could aid in the identification of potential pathogenic strains of atypical EPEC.

BACKGROUND AND OBJECTIVES Enteropathogenic Escherichia coli (EPEC) divided into two groups typical and atypical (aspect). The main virulence genes are located in a pathogenicity island called LEE (Locus of Enterocyte Effacement). LEE frequently inserted in tRNA genes of selC, pheU and pheV in the bacterial chromosome. tEPEC and aEPEC strains have some differences in their pathogenicity. The pur...
متن کامل10.321/eid0805.Typical and Atypical Enteropathogenic Escherichia coli
Typical and atypical enteropathogenic Escherichia coli (EPEC) strains differ in several characteristics. Typical EPEC, a leading cause of infantile diarrhea in developing countries, is rare in industrialized countries, where atypical EPEC seems to be a more important cause of diarrhea. For typical EPEC, the only reservoir is humans; for atypical EPEC, both animals and humans can be reservoirs. ...
متن کاملAtypical Enteropathogenic Escherichia coli: Typical Pathogens?
scherichia coli is both the most abundant facultative commensal of the human gastrointestinal tract and the most common bacterial cause of human diarrhea (1). However, precise recognition of E. coli pathotypes remains problematic. Enteropathogenic E. coli (EPEC), classically associated with outbreaks of infant diarrhea, harbors distinctive chromosomal (the locus of enterocyte effacement, or LEE...

249 enteropathogenic Escherichia coli (EPEC) strains from faecal samples of 90 children with diarrhoea were examined for verotoxin (VT) production. Polymyxin B extracts of 61 strains belonging to 9 serogroups from 35 children produced various verotoxins (VTs). The titre of these various VTs ranged from I :40 to I: 12HO. Of the 26 (43.6%) adherent strains, 19 (73%) exhibited localized adhere...
متن کاملEscherichia coli strains of serotype O51:H40 comprise typical and atypical enteropathogenic E. coli strains and are potentially diarrheagenic.
Escherichia coli strains of serotype O51:H40 were studied with regard to the presence of several virulence properties and their genetic diversity and enteropathogenicity in rabbit ileal loops. This serotype encompasses potential enteropathogenic strains mostly classified as being atypical enteropathogenic E. coli (EPEC) strains, which are genetically closer to enterohemorrhagic E. coli than to ...
