[Comparison of methods for the large-scale culture of cells and viruses].

The paper presents the results of experiments on propagation of primary, secondary, and continuous diploid and heteroploid human and animal cells in 2 different systems for large-scale propagation: in perfusion tank with Rashig rings and in tanks with microcarriers. Both methods of large-scale cultivation produce higher cell yields than the traditional cultivation methods. A yield of tick-borne encephalitis virus per 1 cell in the perfusion cultivator was 12 times as high as in roller cultures. Poliomyelitis virus titres were practically equal with both methods of large-scale cultivation and with the conventional method (7.73 lg PFU/ml in GMKC on microcarriers). The method of cultivation on microcarriers is more acceptable and advantageous as it gives higher yields of cells necessary for growth of poliomyelitis virus.
