The incidence of anti-amebic precipitins was determined in sixteen different populations. These included hospitalized patients in Durban and blood donors of various racial groups in Durban, Johannesburg and Capetown. Correlation was found between the prevalence of antibodies and the incidence of invasive amebiasis. The observation indicates the value of the serological approach in determining the importance of Entamoeba histolytica as a pathogen in populations and areas. Its objectivity gives it an additional advantage over stool survey.
