Virulence markers of enteroaggregative Escherichia coli isolated from children and adults with diarrhea in Brasília, Brazil.
Escherichia coli strains isolated from sporadic cases of acute diarrhea in children and adults and from children without diarrhea were investigated for the presence of the pAA plasmid. Strains harboring the pAA plasmid were isolated at similar frequencies from children with (19.6%) and without (10.8%) diarrhea and from adults with diarrhea (11.8%). The genotypic and phenotypic virulence markers...
متن کاملGenetic Virulence Profile of Enteroaggregative Escherichia coli Strains Isolated from Danish Children with Either Acute or Persistent Diarrhea
Enteroaggregative Escherichia coli (EAEC) is frequently found in diarrheal stools worldwide. It has been associated with persistent diarrhea, weight loss, and failure to thrive in children living in developing countries. A number of important EAEC virulence genes are identified; however, their roles in acute and persistent diarrhea have not been previously investigated. The aim of this study wa...
متن کاملEnteroaggregative escherichia coli virulence factors in traveler's diarrhea strains.
Enteroaggregative Escherichia coli (EAEC) is associated with diarrhea in Spanish travelers to developing countries. In this study, the polymerase chain reaction was used to test EAEC isolates for genes encoding putative virulence factors, including EAEC adhesins, the plasmid-encoded toxin (Pet), a heat-stable enterotoxin (EAST), and Shigella enterotoxins 1 and 2 (ShET1 and ShET2). Findings incl...
متن کاملPhenotypic and Genotypic Characterization of Enteroaggregative Escherichia coli Strains Isolated From Diarrheic Children in Iran
BACKGROUND Several studies performed in developed and developing countries have identified enteroaggregative Escherichia coli (EAEC) as the emerging cause of pediatric diarrhea. OBJECTIVES This study investigated the phenotypic and genetic characteristics of EAEC strains isolated from children with diarrhea between 2007 - 2008 in Tehran, Iran. MATERIALS AND METHODS EAEC strains were examine...
متن کاملphenotypic and genotypic characterization of enteroaggregative escherichia coli strains isolated from diarrheic children in iran
conclusions these results indicated that eaec strains isolated from iranian children with diarrhea were heterogeneous and showed high resistance rates against commonly used antibiotics, which was similar to that reported in studies performed in other countries. results significant percentage of local eaec strains carried the virulence plasmid genes and formed biofilms. in addition, these strain...
