 AB    OBJECTIVES: To compare the prevalence of Blastocystis hominis in
       different population categories in Paris, including immunodepressed
       subjects. METHODS: Stool examinations were performed for 7,677 patients
       to determine the prevalence of Blastocystis hominis. RESULTS: Prevalence
       varied according to the population group: subjects free of any digestive
       tract disorders 17.4%; adults with digestive tract disorders 19.8% (this
       level was independent of digestive tract motility and of ethnic origin);
       children 13.8% (p < 0.01). In HIV-positive patients, the prevalence in
       immunocompetent patients was 19.6% compared with 15 to 16% in patients
       with AIDS (difference non significant). Blastocystis hominis was shown
       to be non-contagious in children and was not found to be sexually
       transmitted in homosexual men. CONCLUSION: Generally, Blastocystis
       hominis infection resolves spontaneous before any manifestation of the
       protozoa. This common parasite is a commensal germ of the intestinal
       tract, even in subjects free of gastro-intestinal manifestations, and
       does not usually require prescription of an antibiotic. In exceptional
       cases with rapid proliferation, treatment can be proposed with
       nitroimidazol, particularly for certain strains with an abnormal
       variability.
