Amoebiasis among institutionalized psychiatric patients in Taiwan.
Although information on amoebiasis among institutionalized psychiatric patients is available, reports on the relationship between behaviour and this infection are not abundant. From July 1995 to June 1996, stool and blood samples were collected from 565 patients in three psychiatric hospitals of North Taiwan. Stool samples were examined using the direct smear and formalin-ethyl acetate sedimentation techniques as well as ProSpecT Entamoeba histolytica Microplate Assay kit. Blood samples were examined by the Amebiasis Serology Microwell ELISA kit. Among these patients, 14 (2.5%) harboured one or two species of intestinal parasites. There were 6 (1.1%) E. histolytica/E. dispar cyst passers: 5 positive in stool ELISA test and 2 with antibodies against E. histolytica. Among demographic factors, type of psychiatric disorder and disability, only a significant sexual difference in seropositivity of E. histolytica was observed. These findings indicate that the infected patients acquired the infections before they entered the hospitals.
