Pentatrichomonas hominis and Tritrichomonas foetus (cat genotype) have been commonly identified as intestinal trichomonads in both dogs and cats. Although P. hominis is considered as non-pathogenic protozoa in many kinds of mammals, it has the potential for zoonotic transmission. T. foetus has been recognized as the emerging causative agent of diarrhea in cats without the risk of zoonotic transmission. As pet shops are the major source of young companion animals, the present study discusses the molecular prevalence of P. hominis and T. foetus from 544 pet shop puppies and 409 kittens. The results suggest that the prevalence of P. hominis (puppies: 7.0%; kittens: 0.5%) and T. foetus (puppies: 0%; kittens: 2.4%) in pet shop young animals are low. In addition, the infections of P. hominis and T. foetus are not always associated with the clinical signs (soft or diarrhea feces).
人毛滴虫和胎儿三毛滴虫（猫基因型）通常被认为是犬猫肠道毛滴虫。虽然人毛滴虫被认为是许多哺乳动物中的非致病性原生动物，但它具有人畜共患传播的潜力。胎儿三毛滴虫已被认为是猫腹泻的新兴病原体，但不存在人畜共患传播的风险。由于宠物店是年轻伴侣动物的主要来源，本研究讨论了从 544 只宠物店幼犬和 409 只小猫中分离出的人毛滴虫和胎儿三毛滴虫的分子流行率。结果表明，宠物店幼小动物中，人毛滴虫的流行率（幼犬：7.0%；小猫：0.5%）和胎儿三毛滴虫的流行率（幼犬：0%；小猫：2.4%）较低。此外，人毛滴虫和胎儿三毛滴虫的感染并不总是与临床症状（软便或腹泻粪便）相关。
