摘要: Although the pathogenicity of Blastocystis hominis has been extensively debated in medical literature, controlled studies association between B. and diarrhea are lacking. We conducted a case-control study among expatriates tourists Kathmandu, Nepal, which we compared prevalence organism patients with to that control group without diarrhea. was detected 56 (30%) 189 diarrhea, 40 (36%) 112 asymptomatic controls. Patients were significantly more likely have > or = 10 organisms per high-power (400x) field than However, 25 this concentration organisms, other enteric pathogens 17 (68%). Only 8 (4%) had absence pathogens, 5 (5%) Thus, higher concentrations not associated There no specific symptoms infection, presence stool more-severe symptoms. Despite high travelers results suggest does cause population.
