Prevalence of intestinal parasitosis in patients afferent to the Hospital of Desio (Monza e Brianza), Italy

Abstract

From may 2008 to June 2010 we have analyzed faecal samples of 2306 subjects: in the subjects was performed the coproparassitological standard examination and in 523 of them was performed scotch test. Of the 2306 subjects examined, 101 resulted positive, 59 to the coproparasitological exam, 43 to scotch test, and 1 to both of them (Taenia spp.). In three cases we have found positivity for two different parassitological species. Pathogenic parasites were found in 77 cases, 61 autoctones and 16 immigrates. The helminths found were Enterobius vermicularis, the prevalent, and Taenia spp., Ascaris lumbricoides, Diphillobothrium latum, Trichuris Trichiura, while the Protozoa were Giardia duodenalis and Entamoeba histolytica/dispar. Non pathogenic species were found in 27 cases, 15 among autoctones and 12 among immigrates: in detail Entamoeba coli, Endolimax nana, Blastocystis hominis. The total prevalence of parassitosis is low (4,2%), 20,0% in immigrate subjects and 3,4% in native subjects. Our results show that the 0-10 age group have an higher prevalence for Enterobius vermicularis. Some considerations are related for improving the complete or more exhaustive diagnosis concerning the intestinal parasitosis.
