title: [Combination of radioimmunological and immunoelectron microscopic methods for detecting hepatitis A virus].
abstract: The possibility of combined performance of radioimmunoassay (RIA) and immune electron microscopy (IEM) in one preparation using protein A of Staphylococcus aureus for hepatitis A virus (HAV) detection in fecal specimens from hepatitis A patients within a short time (40-50 min) has been demonstrated. In the examinations of one preparation by RIA and IEM, their sensitivity was found to be approximately similar. According to RIA, a high content of HAV antigen was observed in those preparations where in addition to typical particles there were structures resembling individual fragments of empty HAV particles coated with antibody.
