Bicozamycin was compared with a placebo in a prospective, randomized, double-blind study of the prevention of acute diarrhea among 30 American travelers newly arrived in Guadalajara, Mexico. None of the 11 subjects given bicozamycin orally for 3 wk at a dosage of 500 mg four times a day developed diarrhea as compared with an incidence of 53% diarrhea (10 of 19 subjects) in the placebo group (p = 0.003). Bicozamycin was well tolerated. Studies of changes in predominant aerobic fecal flora among the 11 subjects treated with bicozamycin showed the appearance of only one highly resistant Citrobacter freundii at the end of 1 wk of therapy and only a total of six resistant isolates at the end of 3 wk. All resistant isolates failed to transfer this resistance to a recipient Escherichia coli. Bicozamycin seems to be well suited and safe as a prophylactic agent against traveler's diarrhea.

The efficacy of bicozamycin, a poorly absorbable antibiotic, in the treatment of acute diarrhea was assessed in a prospective, double-blind study of 140 adults from the United States visiting Guadalajara, Mexico. Patients randomly received bicozamycin (500 mg orally four times daily) or placebo for 3 days. The mean duration of illness was shorter in the bicozamycin than the placebo treatment groups for patients with diarrhea due to Shigella (37 versus 96 hours; p = 0.01), toxigenic Escherichia coli (31 versus 60 hours; p = 0.003), and unknown pathogens (18 versus 41 hours; p = 0.02). Cramps were significantly relieved by bicozamycin in all patients. Treatment failed in significantly fewer patients treated with bicozamycin than those treated with placebo when diarrhea was associated with Shigella, Salmonella or toxigenic E. coli. Bicozamycin was well tolerated and appears to be effective therapy for acute travelers' diarrhea of diverse causes. These data show the value of an antibiotic in the therapy of toxigenic E. coli infection and indicate a need to reevaluate the clinical dictum that nonabsorbable antibiotics are ineffective against invasive enteropathogens.
