摘要: The prevalence of antibodies against Entamoeba histolytica was studied in the Mexican population using an immunoenzyme assay solid phase (ELISA) and semiautomatic equipment. antigen a mixture membrane proteins obtained by Triton X-100 extraction from axenic culture HM1-IMSS. method standardized comparing serum samples amoebic liver abscess patients with healthy volunteers. From 60538 supplied National Seroepidemiology Survey, were found 4·49% (4·32—4·65% at 95% confidence limit). More significant titres occurred central region country. ratio female to male 1·25:1. living metropolitan areas had probably been infected younger age than those country. Important differences seroprevalence ELISA compared study which used indirect haemagglutination (IHA) same sample frame.
