A parasitologic survey of 620 mentally retarded patients, institutionalized in five different facilities in Kanagawa Prefecture, revealed a high incidence (12.6%) of infection with Entamoeba histolytica. A concomitant serologic survey, by the indirect fluorescent antibody test, gave a much higher incidence (26.5%). Moreover, most zymodeme patterns of the amebae isolated from infected individuals were of a pathogenic type (Zymodeme II). Our findings demonstrate that the mentally retarded in Japan, as in the United States, still are plagued by a high rate of amebic infection.
