全球范围内,动物和人类遭受腹泻疾病由于原生动物寄生虫如贾第虫和艾美球虫物种。本文综述了日本这些寄生虫的分子流行病学。在人类中,研究人员只发现了一种主要的贾第虫,最被称为G.Lamblia,但它也被称为不同的名字像G.十二指肠或G.肠。然而,在这个物种中,六个组合(A,B,C,D,E,和F)在动物中发现,组合B经常记录在人类和猴子种群中,而组合A和E在小牛中占主导地位。在梅花鹿和组合A中发现了组合A,C,D,F在狗中占主导地位,猫,还有雪貂.牛艾美球虫,E.zuernii,在动物中发现的其他物种构成了被称为艾美球虫的物种群。,牛E.bovis和E.zuernii在牛中最常见。我们的评论强调了有关水和环境来源中这两种病原体的数据调查的明显缺乏。在对水源进行的少数研究中发现了贾第鞭毛虫囊肿,这表明水可能在贾第虫物种的传播中起重要作用。我们的评论表明,有必要进一步研究以充分理解贾第虫的分子多样性和传播动力学。和艾美球虫。在人类中,动物,和日本的环境来源。
Globally, animals and humans suffer from diarrheal illnesses due to protozoan parasites such as Giardia and Eimeria species. The molecular epidemiology of these parasites in Japan is summarized in this
review. In humans, researchers found only one main species of Giardia, which is most referred to as G. lamblia, but it\'s also known by different names like G. duodenalis or G. intestinalis. However, within this species, six assemblages (A, B, C, D, E, and F) were found in animals, and assemblage B was frequently recorded in human and monkey populations, whereas assemblages A and E were predominant in calves. Assemblage A was found in sika deer and assemblages A, C, D, and F were predominant in dogs, cats, and ferret. Eimeria bovis, E. zuernii, and other species found in animals made up the group of species known as Eimeria spp., with E. bovis and E. zuernii being the most common in cattle. Our
review highlighted a notable lack of data investigations regarding these two pathogens in water and environmental sources. Giardia cysts were found in the few studies that have been done on water sources, suggesting that water may play a significant role in the transmission of Giardia species. Our
review suggests that further research is necessary to fully comprehend the molecular diversity and dynamics of transmission of Giardia spp. and Eimeria spp. in humans, animals, and environmental sources in Japan.
