Diarrhoeal diseases constitute one of the most important causes of illness and death all over the world. In Nigeria, the epidemiology of diarrheagenic bacteria and the virulence of the various E. coli pathotypes have not been well studied because most of the currently published data were from the southwestern axis leaving the southeast and north unstudied. 520 stool samples were collected from ...

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...

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...

OBJECTIVES To select rifaximin-resistant mutants of Escherichia coli and to establish the frequency of mutation, cross-resistance with other antimicrobial agents and the stability of the mutants obtained. METHODS Four E. coli isolates [two enteroaggregative E. coli (EAEC) and two enterotoxigenic E. coli (ETEC)] were used to obtain rifaximin-resistant mutants. The frequency of mutation in the ...

Diarrheogenic Escherichia coli (DEC) strains are an important cause of intestinal syndromes in the developing world mainly affecting children. DEC strains often infect tourists from developed countries traveling to Mexico, causing so-called "traveler diarrhea". DEC strains are typically transmitted by contaminated food and water; however, the prevalence of these strains in food items that are p...
