1. The epidemiological study of human diphyllobothriasis in Japan (1882-2001)
The human diphyllobothriasis cases reported in Japan (1882-2001), D. nihonkaiense 1,753, Dlplo. grandis 269, larval infection of S. erinacei and adult infection of S. erinacei, were epidemiologically and parasitologically analysed to study the infection tendency, infectious sources, diagnosis, treatment and preventive measures.
2. The specimen collection for the taxonomical study in Japan (2000-2003)
The 20 cases of D. nihonkaiense, and the 4 cases of Diplo. grandis were collected with the collaboration of universities and hospitals in Japan for the taxonomical study, and also the treatment methods, especially the Gastrografin method, was evaluated.
3. The infection survey of the migratory birds from Russia to Japan
The migratory birds, 10 tufted ducks, Aythya fuhgula(Rinneus), fried over the Japan Sea from Russia to Hikawa River, Izumo, Japan were examined for the cestode infection to defined the final host, howe
ver no larvae were found in the gut of tufted ducks.
4. The collaborative epidemiological study with the neighboring countries around Japan Sea
The human cases of diphyllobothriasis occurred, in Korea were defined as D. nihonkaiense and Diplo. grandis. The infectious sources were raw masu salmon and marine fish served as Sashimi and hors d'oeuvre. We-could not collect the specimens of cestodes from China, Mongolia and Russia.
5. The parasitological study of marine mammals
The parasitological study of marine mammals was performed with the collaboration of the 36 aqualiums in Japan, and 6 specimens of undefined cestode strobilae were collected. The taxonomical study was continued.
6. The paleoparasitological study of the ruins of Aoki, Izumo in Japan
The paleoparasitological study of the ruins of Aoki, c.300B.C.-c.300A.D., Izumo in Japan was performed. Two human skeletons were excavated, however, no parasite eggs were found in the soil.
7. The summary and review of the study ~ -
The results of the taxonomical, epidemiological and ecological study of human diphyllobothriasis in Japan were summarized into the review article. Less
