[Prevalence of intestinal parasitic disease in three provinces in Morocco].

A study of intestinal parasites was carried out in Taounate, Béni Mellal and Tizinit provinces in Morocco on a sample of 1682 individuals who were representative of the urban and rural area population. For each stool specimen, three microscopic examinations and a Kato test were performed. In the three provinces, about two-thirds of the study participants from rural areas and around 50% of those from urban areas had parasites. The reproducibility of the prevalence figures allowed the study results be generalized to the other provinces of the country. Among the parasite groups encountered, amoebas were the most frequent, followed by flagellates and helminths. Concerning pathogenic species, Entamoeba histolytica, in the amoebic group, was the most commonly found. All the positive cases were treated by specific medication.
