摘要: Abstract Sera from nine populations in Surinam, South America, were screened for antibodies against Entamoeba histolytica by the enzyme-linked immunosorbent assay (ELISA) technique and a precipitin test (gel diffusion or counterimmunoelectrophoresis). In two small surveys 1974 1978, high rate of clinically significant ELISA titers was found rather isolated group Amerindians living near Brazilian border, predominately youngest age groups. coast showed low level seropositivity. Low levels also Bush Negro villages interior Surinam Hindustani school children savannah area. A frequency ⩾320, indicating invasive amebiasis, detected persons mental institution Paramaribo. It is concluded that ELISA, which much more sensitive than tests, useful screening assessing prevalence amebiasis on an epidemiological scale.
