贾第鞭毛虫被认为是人类和动物的重要病原体，引起腹泻。最近的分子生物学研究表明G.基因组由遗传上不同的多种基因型组成。因此，在人和动物贾第虫感染的流行病学中区分基因型是有价值的。虽然G.在日本的人类和动物中发现了沙门氏菌，但由于仅通过常规显微镜进行鉴定，因此分离株的基因型仍不清楚，只有几个犬分离株除外。本文报道了G.通过系统发育分析区分的大肠杆菌分离株。G.发现来自患者和小牛的沙门氏菌分离株分别具有集合体B和E。
Giardia intestinalis is recognized as a significant pathogen in humans and animals, causing diarrhea. Recent molecular studies indicate that G. intestinalis is composed of genetically distinct multiple genotypes. Therefore, it is valuable to distinguish among genotypes in the epidemiology of Giardia infection in humans and animals. Although G. intestinalis has been found in humans and animals in Japan, the genotype of isolates remains unclear except for several isolates from dogs, because identification has been performed only by conventional microscopy. We report herein the genotypes of G. intestinalis isolates distinguished by a phylogenetic analysis. G. intestinalis isolates originated from a patient and a calf were found to have Assemblage B and E, respectively.
