title: Immunofluorescent IgG and IgM antibodies in human sera by enterovirus infections.
abstract: IgG and IgM antibodies to selected enterovirus serotypes (P2, CB 1-5, E2, 4, 20), to prototype collection strains and to fresh isolates were examined by immunofluorescence in paired sera of 11 children and 4 adults in whom enterovirus had been isolated, or a rise of specific antibodies had been proved by neutralization test. One six-month- and one seven-month-old child had antibodies of both classes to the isolated virus strain and to poliovirus only. Children from eight month onwards and adults had antibodies to the majority of enterovirus serotypes tested. Among all enteroviruses tested, heterologous reactions were observed not only with IgG but also with IgM class antibodies.
