title: [The effectiveness of lanthanide immunofluorescence and immunoenzyme analyses in differentiating viruses of the tick-borne encephalitis complex].
abstract: Comparison of the efficacy of time-resolved fluoroimmunoassay (TR-FIA) and two variants of enzyme immunoassay: conventional (EIA-1) and one using biotin-streptavidin system (EIA-2), in differentiation of viruses of the tick-borne encephalitis complex showed that, their specificity being similar, the TR-FIA method was 2-4 times as sensitive as EIA-2 and 8-32 times as sensitive as EIA-1. When the reactivity of the antigens was assessed by titers, the differentiating capacity was found to be similar and to depend upon the specificity of "sandwich"-forming antibodies and the sensitivity of the immunoassay. When the reactivity of the antigens was assessed by relative reactivity in 4 test systems of different compositions, the differentiating capacity of TR-FIA was higher than that of EIA-1 and EIA-2 which allowed additional differentiation of 2 groups of viruses on the basis of qualitative characteristics of reactivity.
