Among 750 symptomatic and asymptomatic patients, was detected at a prevalence of 5.2% and more common than . Most infected patients presented with diarrhea and abdominal pain with symptoms greater than 2 weeks duration being common. Bacterial and viral causes of infection were excluded by routine microbiological techniques. Treatment of infection with either iodoquinol, paromomycin, or combination therapy resulted in the eradication of the parasite and complete resolution of symptoms. Treatment failure/relapses were associated only with the use of metronidazole. Nineteen patients were examined for pin worm, no , a proposed vector of transmission, were detected. Intermittent shedding of was found to be highly variable. These studies confirm the pathogenic nature of and we recommend laboratories routinely test for the organism.
