background: escherichia coli is the most causative agent of urinary tract infections (utis). apart from all human infectious diseases, uti have a high prevalence and in most cases, escherichia coli is a dominance bacterium which can cause pyelonephritis and cystitis. the aim of the study was to determine the occurrence of some virulence genes expressing fimbriae, production of hemolysin and aer...

Although part of the normal gut flora, Escherichia coli strains are also important intestinal pathogens. Diarrheagenic E. coli (DEC) cause a wide variety of gastrointestinal diseases, particularly among children in developing countries, resulting in significant morbidity and mortality (Moyo, 2007; Khairun, 2007; Brandal, 2007; Nguyen, 2005; Rajendran, 2010; Franzolin, 2005). The DEC are differe...

Diarrheagenic Escherichia coli (DEC) is important bacteria of children's endemic and epidemic diarrhea worldwide. The aim of this study was to determine the prevalence of DEC isolated from stool samples collected from children with acute diarrhea living in Ouagadougou, Burkina Faso. From August 2013 to October 2015, stool samples were collected from 315 children under 5 years of age suffering f...

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 combining five specific primer pairs ...

BACKGROUND Diarrheal diseases can be caused by viral, bacterial and parasitic infections. This paper provides a preliminary image of diarrhea with regards to etiology and epidemiologic factors in Tunisian children less than five years of age. METHODS Overall, 124 diarrhoeal stools were collected from patients suffering from acute diarrhea and 54 stool samples from healthy children. All stools...

This case-control study detected and characterized Shigella and diarrheagenic Escherichia coli (DEC) types among Vietnamese children less than 5 years old. In 249 children with diarrhea and 124 controls, Shigella spp. was an important cause of diarrhea (P < 0.05). We used multiplex PCR and DNA probes to detect enteroinvasive E. coli (EIEC), enteroaggregative E. coli (EAggEC), enteropathogenic E...

Escherichia coli (E. coli) is the predominant nonpathogenic facultative flora of the human intestine [1]. However, several strains of E. coli have developed the ability to cause disease in humans. Strains of E. coli that cause gastroenteritis in humans can be grouped into six categories: enteroaggregative (EAEC), enterohemorrhagic (EHEC), enteroinvasive (EIEC), enteropathogenic (EPEC), enteroto...

&lt;em&gt;Sansevieria trifasciata&lt;/em&gt; is a plant that has the potential to kill pathogenic bacteria due its content. An experimental study with laboratory design was carried out test inhibition of extract against &lt;em&gt;Escherichia coli&lt;/em&gt; in vitro. Antibacterial testing at concentrations 5%, 10%, and 40% explore growth Escherichia coli by maceration method using 96% ethanol. ...

background: organisms producing ctx-m-β-lactamase are emerging around the world as a source of resistance to oxyiminocephalosporins such as cefotaxime. however, the laboratory detection of these strains is not well defined. the aim of this study was to determine the presence and prevalence of known ctx-m-β-lactamases genes in clinical isolates of  escherichia coli from hospitals of tehran. meth...

diarrheal diseases can be caused by viral, bacterial and parasitic infections. this paper provides a preliminary image of diarrhea with regards to etiology and epidemiologic factors in tunisian children less than five years of age.overall, 124 diarrhoeal stools were collected from patients suffering from acute diarrhea and 54 stool samples from healthy children. all stools were examined for the...
