[Frequency of human parasites in selected populations of Silesian region].

Epidemiological evaluation of the most frequent human parasitoses in the group of children at age of seven years, in adult patients and in group of Polish citizens coming back from tropics between 1999-2003 was performed. All examined people were Silesian region inhabitants. The biggest average infection prevalence in children from all examined years concerned Enterobius vermicularis, in adult--Giardia intestinalis, while in group of population coming back from tropics--Entamoeba histolytica-like. High percentage of anti-Toxocara canis and Toxoplasma gondii antibodies presence can result from non randomly study group recruitment.
