Antigenic relatedness of two strains of hepatitis A virus determined by cross-neutralization

|October 1, 1983
Abstract:
Cell culture-adapted HM-175 (Australia) and PA-21 (Panama) strains of hepatitis A virus were compared in a cross-neutralization radioimmunofocus inhibition assay. The ratio of antibody titers achieved with two sera against the two viruses differed by less than twofold, indicating a high degree of antigenic relatedness between epidemiologically disparate strains of virus.
