Travellers' diarrhoea: contemporary approaches to therapy and prevention.

Travellers' diarrhoea remains a major public health problem, contributing to significant morbidity and disability. Because bacterial enteropathogens cause a majority of this form of diarrhoea, antibacterial drugs are effective when used in chemoprophylaxis or for empirical treatment.A review of the MEDLINE listings for travellers' diarrhoea for the past 4 years was conducted; a library of >1,000 scientific articles on the topic was also considered in developing this review.

Enteroaggregative Escherichia coli diarrhea in travelers: response to rifaximin therapy.

Background And Aims: We have recently shown that enteroaggregative Escherichia coli (EAEC) strains commonly cause travelers' diarrhea. The study was designed to determine whether U.S.

Azithromycin found to be comparable to levofloxacin for the treatment of US travelers with acute diarrhea acquired in Mexico.

Increased drug resistance among enteropathogens is an emergent problem in travelers' diarrhea. This randomized, double-blind trial was conducted in Guadalajara, Mexico, during the summers of 1999-2001 to compare azithromycin with levofloxacin for the treatment of travelers' diarrhea. A total of 217 US adults were randomized to receive a single oral dose of azithromycin (1000 mg; 108 persons) or levofloxacin (500 mg; 109 persons), with a follow-up period of 4 days.

Rifaximin versus ciprofloxacin for the treatment of traveler's diarrhea: a randomized, double-blind clinical trial.

Rifaximin is a poorly absorbed rifamycin derivative under investigation for treatment of infectious diarrhea. Adult students from the United States in Mexico and international tourists in Jamaica were randomized to receive either rifaximin (400 mg twice per day) or ciprofloxacin (500 mg twice per day) for 3 days, following a double-blinded model, from June 1997 to September 1998. A total of 187 subjects with diarrhea were studied.
