| Summary |
Use of microcarriers, cytodex 1, for cultivation of BHK - 21 and RK- 13 cells could be easily carried out in a microcarrier flask. The highest concentration of the cells ape-ared on day 3 for BHK - 21 and 4 for RK - 13 cells.
Multiplication of Pseudorabies ( PR ) virus inmicrocarrer system did not yield high-er virus titer than the roller bottle technigue. However, some advantages were found by using microcarrier system. .
