[Neutralizing antibodies to Coxsackie virus group B 1986-1988].
Presence of neutralizing antibodies to Coxsackie B viruses (CBV) 1-5 were examined in 2885 human sera by the neutralization test. The most frequently detected antibodies were to B4 viruses (in 1495 sera--51.82%) and to B3 (1371--47.52%). Antibodies to other serotypes were found in lower percentage: to B1 in 387 samples (13-41%), to B2 in 404 sera (14%) and in B5 in 332 sera (11.5%). Presence of neutralizing antibodies to human CBV in heart diseases were also analysed in 67 serum pairs. In this group of examinees the antibody titer dynamics was found in 41.79% sera.
