Treatment of intestinal amoebiasis and giardiasis; efficacy of metronidazole and tinidazole compared.

Aboriginal children who were aged from six to nine years and living in Cherbourg Community were treated for Giardia Lamblia and Entamoeba histolytica infection with either the manufacturer's recommended dose of metronidazole (Flagyl) or with tinidazole (Fasigyn), at two-dose levels. Tinidazole successfully cleared both protozoans from stools, a single dose being as effective as the longer regimens which were studied. The obvious advantage of single-dose administration is that it should permit more effective treatment of these intestinal parasites, especially in Aboriginal populations.
