[Attempts to adapt BNK cells to cultivation in suspension and study of the antigenic properties of foot-and-mouth diseases viruses obtained from them]

Abstract

Experiments were carried out to cultivate the foot-and-mouth disease virus under laboratory conditions in a suspension of the BHK-21 cell line. Results showed that the number of cells cultivated in a susfor 48 to 72 hours of incubation reaches up to 2.2 X 10(6). It was also found that certain conditions should be observed for the successful cultivation of the cells in suspension, such as aeration, pH, and respective temperature. It was demonstrated that foot-and-mouth diseases viruses obtained from BHK cells propagating in suspension possess good antigenic and immunogenic properties.
