is a common gut protist of humans and various animals worldwide, with a high level of genetic diversity. Neither its zoonotic potential and transmission routes nor its pathogenicity are fully known. This fact, and the fact that is the most abundant eukaryote in human faeces, raises the question of its relevance to public health. Here, we summarise (in relation to other reports) the results of studies on the prevalence and genotypic variation of , which were carried out in animals, humans, and in water environments in Poland. In humans, the prevalence ranged between 0.14 and 23.6%, in some animals reached 58.97%, and in water environments was 5.1%. Seven subtypes were identified in humans (ST1-ST4, ST6, ST7, and ST9), of which ST3 was the most common. Among animals (wild, livestock, and pet animals), eleven STs were identified, with differential host specificity. Humans and animals shared ST1, ST2, ST3, ST6, and ST7, while ST1 and ST3 were present in humans, animals, and water sources. These observations indicate the possibility of transmission between animals and humans. Further studies should be continued in search of the sources and transmission routes of in order to prevent the spread of infections among humans and animals.
是一种在全球人类和各种动物肠道中常见的原生生物，具有高度的遗传多样性。其人畜共患病潜力、传播途径以及致病性均未完全明确。鉴于此，以及它是人类粪便中最丰富的真核生物这一事实，引发了其与公共卫生相关性的问题。在此，我们（与其他报告相关）总结了在波兰的动物、人类和水环境中开展的关于该生物流行率和基因型变异的研究结果。在人类中，流行率在0.14%至23.6%之间，在某些动物中达到58.97%，在水环境中为5.1%。在人类中鉴定出七种亚型（ST1 - ST4、ST6、ST7和ST9），其中ST3最为常见。在动物（野生动物、家畜和宠物）中，鉴定出十一种ST，具有不同的宿主特异性。人类和动物共享ST1、ST2、ST3、ST6和ST7，而ST1和ST3存在于人类、动物和水源中。这些观察结果表明该生物在动物和人类之间传播的可能性。应继续开展进一步研究以寻找其来源和传播途径，从而预防感染在人类和动物之间的传播。
