[Differentiation of foot-and-mouth disease viruses by counterimmunoelectrophoresis].

Studied were the opportunities for employing the method of counter immunoelectrophoresis (CIE) to differentiate F. M. D. viruses of different origin, comparing the results obtained with those reached through the immunodiffusion test (IDT). It was found that CIE could be used successfully for the serotyping of F. M. D. viruses, the method being as precise as IDT, however, the results are recorded at the 90th minute, while IDT requires at least 24 hours to read the results.
