1. DIARRHEAGENIC Escherichia coli IN RAW MILK, WATER, AND CATTLE FECES IN NON-TECHNIFIED DAIRY FARMS
Resumo Este estudo teve como objetivo realizar a detecção de Escherichia coli diarreiogênica (EPEC, STEC, ETEC e EAEC) em leite, água e fezes bovinas em pequenas propriedades leiteiras localizadas na Região Nordeste do Estado de São Paulo, Brasil. E. coli foi detectada em amostras obtidas de fezes (80%), leite cru (66,67%) e água (55,56%). STEC, EPEC,

2. Virulence factors and phylotyping of Escherichia coli isolated from non-diarrheic and diarrheic water buffalo calves
RESUMO: O objetivo foi determinar os fatores de virulência, os grupos filogenéticos e as possíveis relações entre os patovares e os grupos filogenéticos identificados de cepas de Escherichia coli isoladas de fezes de bezerros bubalinos. Um total de 217 amostras de E. coli foram identificadas a partir de cultura das fezes e submetidas a reação em cad

3. Prevalence of Shiga Toxin-Producing and Enteropathogenic Escherichia coli in Wild and Pet Birds in Iran
ABSTRACT The aim of this study was to investigate the prevalence of Shiga toxin-producing Escherichia coli (STEC) and enteropathogenic E. coli (EPEC) strains and to identify the stx gene types in wild captive and companion birds. In total,657 E. coli isolates from 219 birds belonging to 38 different species were investigated for the presence of STEC and EPEC

4. Typical and atypical enteropathogenic Escherichia coli bacterial translocation associated with tissue hypoperfusion in rats
Although enteropathogenic Escherichia coli (EPEC) are well-recognized diarrheal agents, their ability to translocate and cause extraintestinal alterations is not known. We investigated whether a typical EPEC (tEPEC) and an atypical EPEC (aEPEC) strain translocate and cause microcirculation injury under conditions of intestinal bacterial overgrowth. Bacterial

5. The ability of haemolysins expressed by atypical enteropathogenic Escherichia coli to bind to extracellular matrix components
Typical and atypical enteropathogenic Escherichia coli (EPEC) are considered important bacterial causes of diarrhoea. Considering the repertoire of virulence genes, atypical EPEC (aEPEC) is a heterogeneous group, harbouring genes that are found in other diarrheagenic E. coli pathotypes, such as those encoding haemolysins. Haemolysins are cytolytic toxins tha

6. Transferência de anticorpos reativos com intiminas α, β, γ de Escherichia coli pela placenta e aleitamento materno: determinação quantitativa em soros de recém-nascidos e soros e colostros de suas mães / Transference of antibodies reactive with intimins α, β and γ of Escherichia coli by placenta and breastfeeding: quantitative determination in the sera of newborns and the colostrum and sera of their mothers
Intimina é uma adesina de natureza protéica das bactérias diarreiogênicas Escherichia coli enteropatogenica (EPEC) e enterohemorrágica (EHEC), capazes de induzir a lesão \ attaching e effacing\ em enterócitos. Os principais subtipos de intiminas de EPEC e EHEC prevalentes no Brasil são α, β e γ. Nosso objetivo foi investigar a transfer

7. Random amplification of polymorphic DNA reveals clonal relationships among enteropathogenic Escherichia coli isolated from non-human primates and humans
Enteropathogenic Escherichia coli (EPEC) strains are important agents of infantile diarrhea all over the world, gaining even greater importance in developing countries. EPEC have also been isolated from various animal species, but most isolates belong to serotypes that differ from those recovered from humans. However, it has been demonstrated that several is

8. CARACTERIZAÇÃO DE FATORES DE VIRULÊNCIA EM AMOSTRAS DE Escherichia coli ISOLADAS DE LAGOAS DO PARQUE ESTADUAL DO RIO DOCE, MINAS GERAIS OURO PRETO 2006
The fecal coliforms whose main representative is the Escherichia coli belong to the intestinal flora of humans and other warm-blooded animals, these microorganisms have been extensively used at water quality control and when found at water are an indicator of recent contamination by feces, and as consequence, enteric pathogenic microorganisms are made presen

9. Seric antibodies anti-hemorrhagic Escherichia coli (EHEC) in healthy Brazilian adults / Anticorpos séricos anti Escherichia coli enterohemorrágica (EHEC) em adultos saudáveis da Grande São Paulo
Gastroenteritis is still an important public health problem in developing countries and Escherichia coli are frequent agents of diarrhea. Brazilian adults present antibodies reactive with the principal virulence factors of enteropathogenic E. coli (EPEC), which have many genetic and antigenic similarities with enterohemorrhagic E. coli (EHEC), that may be re

10. Purificação e caracterização de enterohemolisina produzida por Escherichia coli enteropatogenicas
Enterohaemolysins (EHly) were ftrst detected in classical enteropathogenic Escherichia coZi strains (EPEC), isolated from feces of infants with diarrhea, and also detected in strains isolated from animaIs. Differring from a-haemolysin, EHly is not spontaneously released to culture medium. Sonication was the most efficient method to extract EHly. In order to

11. Evidence of Pathogenic Subgroups among Atypical Enteropathogenic Escherichia coli Strains▿
We describe the characterization of 126 atypical enteropathogenic Escherichia coli (aEPEC) isolates from 1,749 Brazilian children. Classic aEPEC strains were more frequently found in children with diarrhea than in controls (P < 0.001), showing their importance as acute diarrhea agents in our country. Only aEPEC strains carrying either the ehxA or paa gene we

12. Interaction of Enteropathogenic or Enterohemorrhagic Escherichia coli with HeLa Cells Results in Translocation of Cortactin to the Bacterial Adherence Site
Infection of cultured HeLa epithelial cells with enteropathogenic Escherichia coli (EPEC) or enterohemorrhagic E. coli (EHEC) O157:H7 results in accumulation of cortactin under the adherent bacteria. Tyrosine phosphorylation of cortactin is not induced following HeLa cell infection with EHEC or EPEC, contrary to what has been reported to occur with Shigella
