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.
隐孢子虫属和贾第虫属是人类及许多其他哺乳动物的肠道原生动物寄生虫。本文旨在总结过去二十年关于这些寄生虫环境分布的研究，特别强调波兰的入侵天然宿主和人类感染情况。已对不同人群、野生动物、宠物和农场动物以及环境样本中的隐孢子虫和贾第虫感染率进行了研究。总结了目前关于人畜共患和非人畜共患物种/基因型在储存宿主和环境样本中分布的知识。介绍了不同方法在不同类型样本中检测和鉴定寄生虫的实用性。由于这两种寄生虫在一系列宿主及可能参与机械传播的媒介中广泛分布且感染率高，波兰隐孢子虫病和贾第虫病暴发的总体风险被评估为相对较高。
