Clinic Comparative Study of Ozone Therapy and Metronidazol in Intestinal Amebiasis J. Bustelo, G. Vega. Dr. Antonio Luaces Iraola Hospital, Ciego de Avila, Cuba. Amebiasis is a disease, generally characterized, by dysentery with diarrhea, weakness and prostration. Also, nausea, vomithing and pain may be present. The aim of this study is to evaluate the efficiency of rectal ozone treatment in children suffering with intestinal amebiasis. The diagnose was made by cysts or trophozoites of E. histolytica in stools. A control group using Metronidazol was used in order to compare both groups. Ozone therapy was useful in the treatment of intestinal amebiasis with 83.8 % of efficiency and only 0.55 % of adverse effects, better than the treatment with Metronidazol who gets 71.1 % of efficiency and 17.7 % of adverse effects.
