[Cryptosporidium spp. and Giardia spp.--environmental studies in Poland].
Cryptosporidium spp. and Giardia spp. are intestinal protozoan parasites of humans and many other species of mammals. The aim of this article was to summarize the last twenty years of research on the environmental distribution of these parasites, with a particular emphasis on the natural reservoir of invasion and human infections in Poland. The prevalence of Cryptosporidium and Giardia has been studied in different groups of humans, in wildlife, pets and farm animals and in environmental samples. Current knowledge on the distribution of zoonotic and non-zoonotic species/genotypes in reservoir hosts and environmental samples has been summarized. The usefulness of different methods for the detection and identification of the parasites in different types of samples has been presented. Due to the wide distribution and high prevalence of both species in a range of hosts and possible vectors involved in mechanical transmission, the overall risk of outbreaks of cryptosporidiosis and giardiosis in Poland has been assessed as relatively high.
