(Strongyloides stercoralis and strongyloidiasis in Umbria: ten years of investigations).The Authors relate prevalences concerning strongyloidiasis in Perugia,Torgiano and Deruta, Provence of Perugia, Region of Umbria, Central Italy, between 1995 and 2004. The specific investigation for Strongyloides stercoralis was initially obtained using Baermann’s Method, and after with a modified tecnique of this method and/or with colture on agar of larvae. During 10 years S. stercoralis had been found in 69 elder subjects in relation to 734 examined people (9.4%).The research of this nematode was usually justified by a periferical hipereosinophilia; infact, among positive people, an increased eosinophilia was documented in 88.4% of subjects. The Authors describe biological features of this worm as for diagnostical aims as for epidemiological findings, in order to understand the persistence in these moist and temperate areas around rivers and lakes of central Umbria.Thus, the Authors report operating procedures to research and/or to exclude this helminthiaisis in Italian and immigrate population, on the base of anamnestical suggestions of potential infection. |
