Abstract;Giardia trophozoites were detected in fecal samples from a pet dog (4 years old) with diarrhea. After treatment with metronidazole, the dog recovered from illness and Giardia was not found in its fecal samples. But detailed examination of the feces revealed Cryptosporidium oocysts too. Consequently this case was diagnosed as a mixed infection of both Cryptosporidium and Giardia. Even after treatment with metronidazole, Cryptosporidium oocysts persisted in the fecal samples. This suggests that metronidazole has no anti-cryptosporidial effects. The Cryptosporidium isolate from this dog was identified as C. canis, specific to dogs, by PCR-RFLP analysis. This is the second report of Cryptosporidium infection in a pet dog and the first case of mixed infection of Cryptosporidium and Giardia in Japan. (author abst.)
