INTRODUCTION A wide diversity of bacterial agents may cause diarrhea, presenting challenges to clinical laboratories to define a diagnosis. Considering that most stool cultures are negative, we screened stool samples from patients with diarrhea for the presence of 14 bacterial enteropathogens, aiming to establish which of them should be included in routine stool analysis. METHODOLOGY Stool sa...

Diarrheagenic Escherichia coli (DEC) represents an elusive target, since they are not easily distinguished from fecal coliforms. To clarify if DEC are prevalent among sporadic cases of diarrheal illness in Osaka City, Japan, diarrheal specimens were examined for E. coli that were enterohemorrhagic (EHEC), enteropathogenic (EPEC), enterotoxigenic (ETEC), enteroinvasive (EIEC), or enteroaggregati...

Escherichia coli is a phenotypically and genomically diverse and versatile bacterial species. Commensal E. coli are valuable to warm-blooded animals (including humans) as part of the intestinal microflora, but pathogenic E. coli can cause a variety of diseases in the same hosts. Human illnesses associated with pathogenic E. coli include infections of the urinary tract, blood stream, meninges, o...

BACKGROUND Diarrheagenic Escherichia coli (DEC) are important bacterial causes of childhood diarrhea in Brazil, but its impact in adults is unknown. This study aimed at investigating DEC among children and adults living in endemic areas. METHODS A total of 327 stools specimens were collected from children (n = 141) and adults (n = 186) with diarrhea attending health centers. Diarrheagenic E. ...

Extraintestinal Escherichia coli (ExPEC), a heterogeneous group of pathogens, encompasses avian, neonatal meningitis, and uropathogenic E. coli strains. While several virulence factors are associated with ExPEC, there is no core set of virulence factors that can be used to definitively differentiate these pathotypes. Here we describe a multiplex of four virulence factor-encoding genes, yfcV, va...

background and objectives: diarrhea is one of the most prevalent diseases in the world, specially in developing countries. one of the most important causative agents of bacterial diarrhea is diarrheagenic escherichia coli (dec) which causes gastroenteritis and this group involving enterotoxigenic e. coli (etec), enteropathogenic e. coli (epec), enteroaggregative e. coli (eaec), enterohemoragic ...

W e have read with interest the Letter to the Editor by Ahmed and Abouzeed reporting on the important issue of enterohemorrhagic Escherichia coli O157 (EHEC O157) in dairy cattle in Libya (1). Based on two cited references, the authors state that: ‘‘Surveys of diarrheal stools from children in African nations, including Libya, have detected EHEC O157 in 8 15% of the samples’’. One of the cited ...

Diarrheal diseases can lead to infections and cause morbidity mortality in children. Diarrheagenic Escherichia coli (DEC) is an etiological agent, which considered the major causative agent of diarrhea children some developing countries. The aims this work were estimate (E. coli) causing less than 5 years old, detect biofilm virulence factors effect antibiotics. For methodology, a total 112 spe...

Background: Diarrheagenic Escherichia coli (DEC) is regarded as a great public health concern all around the world causing diarrhoea which can be transmitted through food chain. Aims: This study aimed to determine the contamination level and exact distribution rate of DEC in food products consumed by human. Methods: Seven hundred and t...
