Coprological Study on Intestinal Infection in Northern Morocco (Provinces of Tangier, Tetuan and Larache)

Abstract

An epidemiological study on intestina parasitisms has been caried out in Northem Molocco (provinces of Tangier, Tetuan and Larache). A comparative Study has been made at a pprivincial, city and areas (urban and rural) level. Also the SPI (simple pamsitation index) and the CPI (comparative parasitation index) distlibution. Methods: The coprological method used were: direct. concentracion (Fulleboln, Telemann and Kato) method and dye test tecnics (Ferric Hematoxilin and E. Chlorazol Blacki. Results: The number of faecal samples were 4643. parasitism people 2637 and the total number of parasites were 4816. SPI 56,79% and CPI 1,83. Among the Plotozoa. Entamoeba coli. follwed by Endolimax nana. Giardia lamblia and lodamoeba buenchlii prevailed, the other species coming a lung distance behind. Among the Helminths Trichurls trlicura prevailed muchmore than theothers: Ascaris lumbricoides followed and on the trird place were Enterobius vermicularis and Hymeenolepis nana. The percentage found for E, vermicularis was very high, since an appropriate technique of diagnosis was not used. The data have been statistically tested. Conclusions: We found a high rate of parasitation in the 3 provinces that have studied and an approximate number of two parasites per person. SPI and CPI are greather in Tetuan and Larache than in Tangier. SPI is bigger in the rural level than in the urban level.
