Dipylidium caninum is a cosmopolitan parasite of companion animals such as dogs and cats. Accidental infection in humans occur mostly in children. Although considerable number of cases were reported from Europe and the Americas, case reports of this zoonotic disease are rather scarce from Asian countries. The aim of this study is to report the results of literature survey on dipylidiasis cases in humans in Japan. Conclusively, we have found a total of 17 cases since the first case report in from Aichi Prefecture in 1925.

We described a human case of zoonotic dog tapeworm, Dipylidium caninum (Eucestoda: Dilepidiidae), rarely occurring in China. The mother of a 17 month-old boy noted the appearance of small white and active worms over a month period in her son's feces, but the boy was asymptomatic except mild diarrhea. We observed 3 tapeworm proglottids resembling cucumber seeds in his stool sample. Microscopically, each proglottid had 2 genital pores, 1 on each lateral edge, and numerous egg capsules in the uterus. The patient was successfully treated with a single oral dose of praziquantel. Adult worms were recovered in the diarrheic stool after praziquantel treatment and purgation. His family had household pet dogs for several years, and he might have acquired the infection by ingestion of infected fleas of his pet dogs. A history of dog or cat pets and flea bites may be important clues to diagnosis of D. caninum infection. The infected pets should also be treated.
