title: [Studies on the giardiasis as the zoonosis].
abstract: To obtain basic data on the route of Giardia infection as zoonosis, we examined feces from 80 dogs and 16 cats for Giardia cysts and evaluated the detection rates. In addition, familial infection was studied in 3 family members of the patient with giardiasis. Giardia cysts were detected in 10 of the 80 dogs (12.5%) but none of the cats. Of the 10 dogs from which Giardia cysts were isolated, 6 had been maintained by the breeders. Tow other dogs were for examination in the research institutions. None of the family members of the patient with giardiasis had this infection. Since the detection rates of Giardia cysts in the dogs and cats were low, the possibility that human infection is acquired from dogs or cats seemed to be low. However, some of patients with giardiasis we encountered had never been abroad. This fact together with the presence of Giardia cysts in the dogs despite the low detection rates suggest that attention should be paid to the possible association between human giardiasis and pets since the number of people keeping pets is increasing.
