1. Bactérias zoonóticas isoladas de Passeriformes silvestres recuperados do tráfico de animais no estado do Ceará/Brasil
RESUMO A ordem dos Passeriformes é uma das mais pressionadas pelas ações antrópicas, especialmente as relativas ao tráfico de animais, que, devido às más condições de manejo e higiênico-sanitárias, favorecem a infecção dos espécimes por patógenos virulentos e zoonóticos, como cepas de Escherichia coli e Salmonella spp., cujo isolamento em sua

2. Captive wild birds as reservoirs of enteropathogenic E. coli (EPEC) and Shiga-toxin producing E. coli (STEC)
ABSTRACT Psittacine birds have been identified as reservoirs of diarrheagenic Escherichia coli, a subset of pathogens associated with mortality of children in tropical countries. The role of other orders of birds as source of infection is unclear. The aim of this study was to perform the molecular diagnosis of infection with diarrheagenic E. coli in 10 diffe

3. Distribution of non-LEE-encoded type 3 secretion system dependent effectors in enteropathogenic Escherichia coli
Enteropathogenic Escherichia coli (EPEC) are important human gastroenteritis agents. The prevalence of six non-LEE genes encoding type 3 translocated effectors was investigated. The nleC, cif and nleB genes were more prevalent in typical than in atypical EPEC, although a higher diversity of genes combinations was observed in atypical 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. Comparison of multiplex PCR with serogrouping and PCR-RFLP of fliC gene for the detection of enteropathogenic Escherichia coli (EPEC)
Enteropathogenic Escherichia coli (EPEC) comprise one of the six categories of diarrhoeagenic E. coli (DEC). EPEC is subgrouped into typical (tEPEC) and atypical (aEPEC). The identification of DEC cannot be based only on cultural and biochemical criteria, since they are indistinguishable from the non-pathogenic E. coli commonly found in human feces. Several

6. 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

7. Clonal relationship among atypical enteropathogenic Escherichia coli strains isolated from different animal species and humans. / Estudo das relações clonais entre amostras de Escherichia coli enteropatogênica atípica de origem animal e humana.
Forty-nine typical and atypical EPEC strains belonging to different serotypes, isolated from humans, pets (cats and dogs), farm (bovines, sheep and rabbits) and wild animals (monkeys) were investigated for virulence markers and clonal similarity by pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). The virulence markers analyzed r

8. Detection of diarrheagenic Escherichia coli from children with and without diarrhea in Salvador, Bahia, Brazil
We identified different diarrheagenic (DEC) Escherichia coli pathotypes isolated from 1,207 children with and without acute endemic diarrhea in Salvador, Bahia, Brazil collected as part of a case-control study. Since the identification of DEC cannot be based on only biochemical and culture criteria, we used a multiplex polymerase chain reaction developed by

9. Etiology of diarrheal infections in children of Porto Velho (Rondonia, Western Amazon region, Brazil)
In the present study, 470 children less than 72 months of age and presenting acute diarrhea were examined to identify associated enteropathogenic agents. Viruses were the pathogens most frequently found in stools of infants with diarrhea, including 111 cases of rotavirus (23.6% of the total diarrhea cases) and 30 cases of adenovirus (6.3%). The second group

10. Prevalence of diarrheagenic Escherichia coli in children with diarrhea in Salvador, Bahia, Brazil
We report the frequency of the different diarrheagenic Escherichia coli (DEC) categories isolated from children with acute endemic diarrhea in Salvador, Bahia. The E. coli isolates were investigated by colony blot hibridization whit the following genes probes: eae, EAF, bfpA, Stx1, Stx2, ST-Ih, ST-Ip, LT-I, LT-II, INV, and EAEC, as virulence markers to disti

11. Diarrheagenic Escherichia coli categories among the traditional enteropathogenic E. coli O serogroups: a review
The socalled enteropathogenic Escherichia coli (EPEC) O serogroups include typical and atypical EPEC, enterohaemorrragic E. coli, enterotoxigenic E. coli, and enteroaggregative E. coli. The aim of this article is to review the composition of each O serogroup and the major serotypes, clones, and additional virulence characteristics of each of these diarrheage

12. Evaluation of Multiplex PCRs for Diagnosis of Infection with Diarrheagenic Escherichia coli and Shigella spp.
We have developed two multiplex PCR assays that detect typical and atypical enteropathogenic Escherichia coli (EPEC) isolates, enteroaggregative E. coli (EAEC) isolates, enterotoxigenic E. coli (ETEC) isolates, enteroinvasive E. coli (EIEC) isolates, Shiga toxin-producing E. coli (STEC) isolates, and Shigella spp. The targets selected for each group were eae
