title: A mass occurrence of human infection with Diplogonoporus grandis (Cestoda: Diphyllobothriidae) in Shizuoka Prefecture, central Japan.
abstract: Forty-six cases of human infection with Diplogonoporus grandis were found in Shizuoka Prefecture on the Pacific coast of Central Japan in 1996. The cases were predominantly elderly male patients over 50 years of age. Although all cases were reported from May to September of the year, most of them were diagnosed in June and July. We suspected that the transmission was due to the consumption of raw juvenile Japanese anchovy (Engraulis japonicus), which are seasonally caught in the spring months off the Pacific coast of the Prefecture. In almost a hundred years after its discovery in 1894, there had been more than 180 cases of human diplogonoporiasis recorded in Japan. The high incidence within a relatively short time frame of our investigation is regarded unusual even in this country.
