[A method for detecting the hemagglutinating activity of enteroviruses]

Optimal conditions to reveal the hemagglutinating activity in the Coxsackie viruses of group B and hemagglutination test (HAT) performed by the micromethod are studied and determined. The titre of hemagglutinins revealed in HAT is established to depend on pH of the phosphate-buffer solution, concentration of human erythrocytes and their group attribution. The viruses passaged at the suboptimal temperature 33 degrees C are shown to possess the maximal hemagglutinating activity.
