Enteroaggregative Escherichia coli (EAEC) has been reported to cause traveler's diarrhea and persistent diarrhea in children in developing countries and in immunocompromised patients. To clarify the prevalence of EAEC in traveler's diarrhea, we studied 636 US, Canadian, or European travelers with diarrhea: 218 in Guadalajara, Mexico (June--August 1997 and 1998), 125 in Ocho Rios, Jamaica (Septe...

In China, great differences in economy, social characteristics and hygiene exist between developing and developed regions. A comparative study of infectious diarrhea between two regions was needed. Three groups of diarrheal patients were collected: children ≤5 year-olds from Beijing (developed region) and Henan Province (developing region), and adults over 18 year-olds from Beijing. A questionn...

Despite decades of research on the effects of zinc in infectious diarrhea, there is surprisingly little consensus on how zinc works (or even if it works), on whether zinc’s effects are pathogen-specific, and what patient populations are most likely to benefit from zinc supplementation. Some recent articles focus on the growthpromoting effects of zinc on the pathogen itself, leading the reader t...

An outbreak of gastrointestinal illness with clinical and epidemiologic features of enterotoxigenic Escherichia coli (ETEC) occurred among patrons of a restaurant during April 1991. Illnesses among several groups of patrons were characterized by diarrhea (100%) and cramps (79%-88%) lasting a median of 3-5 days. Median incubation periods ranged from 50 to 56 h. A nonmotile strain of E. coli (E. ...

Abstract Background The diagnostics of travellers’ diarrhoea (TD) has been revolutionised by multiplex qPCR assays. While mostly bacterial aetiology, viruses and parasites account for the disease among 10–20% travellers. Despite this, prospective studies applying assays remain scarce that cover not only bacteria, such as various diarrhoeagenic Escherichia coli (DEC), but also viral parasitic pa...
