Diarrheagenic Escherichia coli in Children from Costa Rica [PDF]

The American Society of Tropical Medicine and Hygiene, 2010
More than 5,000 diarrheal cases per year receive medical care at the National Children's Hospital of Costa Rica, and nearly 5% of them require hospitalization. A total of 173 Escherichia coli strains isolated from children with diarrhea were characterized at the molecular, serologic, and phenotypic level. Multiplex and duplex polymerase chain reactions

Hemolysin-Producing Strains among Diarrheagenic Escherichia coli Isolated from Children under 2 Years Old with Diarrheal Disease

Pathogens, 2020
Even if serotyping based on O antigens is still routinely used by most laboratories for the detection of diarrheagenic Escherichia coli, this method can provide false-positive reactions, due to the high diversity of O antigens.

Maternal milk contains antimicrobial factors that protect young rabbits from enteropathogenic Escherichia coli infection [PDF]

, 2007
Enteropathogenic Escherichia coli (EPEC) colibacillosis represents a major cause of lethal diarrhea in young children in developing countries. EPEC strains also infect numerous mammal species and represent a major economical problem in rabbit industry ...

Draft Genome Sequences of the Diarrheagenic Escherichia coli Collection [PDF]

Journal of Bacteriology, 2012
ABSTRACT We report the draft genome sequences of the collection referred to as the Escherichia coli DECA collection, which was assembled to contain representative isolates of the 15 most common diarrheagenic clones in humans ( http://shigatox.net/new/ ).

Preferential attachment of Escherichia coli to different particle size fractions of an agricultural grassland soil. [PDF]

, 2007
This study reports on the attachment preference of a faecally derived bacterium, Escherichia coli, to soil particles of defined size fractions. In a batch sorption experiment using a clay loam soil it was found that 35% of introduced E.

Extensive genomic diversity and selective conservation of virulence determinants in enterohemorrhagic Escherichia coli strains of O157 and non O157 serotypes [PDF]

, 2007
Background: Enterohemorrhagic Escherichia coli (EHEC) O157 causes severe food-borne illness in humans. The chromosome of O157 consists of 4.1 Mb backbone sequences shared by benign E.

Diarrheagenic Escherichia coli pathotypes isolated from children with diarrhea in the Federal Capital Territory Abuja, Nigeria

Journal of Infection in Developing Countries, 2015
Introduction: Escherichia coli are frequently isolated from diarrheic children in the Federal Capital Territory Abuja, Nigeria, but their virulent properties are not routinely evaluated. Therefore, the etiology of childhood diarrheal disease attributable

Thin aggregative fimbriae from diarrheagenic Escherichia coli [PDF]

Journal of Bacteriology, 1992
Four strains of diarrheagenic Escherichia coli originally isolated from distinct geographic regions were found to produce unusual thin aggregative fimbriae requiring depolymerization in formic acid prior to analysis by sodium dodecyl sulfate-polyacrylamide gel electrophoresis.

Molecular Characterization of Diarrheagenic Escherichia coli from Libya [PDF]

The American Society of Tropical Medicine and Hygiene, 2012
Diarrheagenic Escherichia coli (DEC) are important enteric pathogens that cause a wide variety of gastrointestinal diseases, particularly in children. Escherichia coli isolates cultured from 243 diarrheal stool samples obtained from Libyan children and 50 water samples were screened by polymerase chain reaction (PCR) for genes characteristic of ...
