title: Survey of Cryptosporidium spp. and Giardia spp. infections in various animals at a zoo in Japan.
abstract: A total of 284 fecal samples of 89 species (43 mammalian species and 46 avian species) were examined for Cryptosporidium oocysts and Giardia cysts from 1999 to 2002. Each sample was collected at the zoo located at Osaka in Japan and examined by microscopy after performing the sucrose flotation method and by two immunofluorescent assay kits for detection of Cryptosporidium oocysts and Giardia cysts. Cryptosporidium spp. was found only in a raccoon dog (Nyctereutes procyonoides), and Giardia spp. was detected in a mandarin duck (Aix galericulata) and two ruddy shelducks (Tadorna ferruginea). In this study, the prevalences of these parasites were found to be low. However, these results suggested that the infected animals could serve as a source of contamination for surface water. This is the first report about the survey of Cryptosporidium spp. and Giardia spp. at a zoo in Japan.
