The role of dogs and cats in human cryptosporidiosis has been the focus of much attention. Studies in which genotyping of Cryptospiridium oocysts in feces of dogs and cats have been successful and have demonstrated that most infections in these animals are caused by host-specific C. canis and C. felis, respectively. Most human cases of cryptosporidiosis are associated with C. hominis and C. parvum; C. canis and C. felis are responsible for only a small number of cases. Thus, molecular epidemiologic studies support the contention that the risk of zoonotic transmission of Cryptosporidium spp. from pet cats and dogs is low. Veterinarians can inform their clients of this minimal risk, but nevertheless advise them to minimize contact with pet cat and dog feces.
狗和猫在人类隐孢子虫病中的作用一直是关注的焦点。在这些研究中，对犬和猫粪便中的隐孢子虫卵囊进行基因分型已取得成功，并表明这些动物中的大多数感染分别由宿主特异性的 C. canis 和 C. felis 引起。大多数人类隐孢子虫病病例与 C. hominis 和 C. parvum 相关；C. canis 和 C. felis 仅导致少数病例。因此，分子流行病学研究支持这样的观点，即从宠物猫和狗传播隐孢子虫属的动物传染病的风险很低。兽医可以告知他们的客户这种最小的风险，但仍建议他们尽量减少与宠物猫和狗粪便的接触。
