title: Immunological differentiation of pathogenic and non-pathogenic isolates of Entamoeba histolytica.
abstract: Entamoeba histolytica can act as a harmless commensal organism in the lumen of the large intestine, or can cause invasive amoebiasis. Some workers have suggested that there are two distinct subspecies of this organism, and that only one of these is associated with invasive disease. Present isoenzyme tests to identify the subspecies take several days to analyse: we report a technique that uses immunofluorescence with monoclonal antibodies, takes two days to perform, and may, therefore, assist in the clinical management of patients infected with this organism.
