A novel process for the production of a veterinary rabies vaccine in BHK-21 cells grown on microcarriers in a 20-l bioreactor

Résumé

We studied BHK-21 cells growth in a 2-l bioreactor and investigated the effects of microcarrier concentration, type of growth medium, culture mode and serum concentration. The highest cell density reached was equal to 4x10(6) cells/ml and was achieved in minimum essential medium supplemented with Hanks' salts, non-essential amino acids and 5% fetal calf serum, using a perfusion culture mode and a microcarrier concentration of 4 g Cytodex 3/l. We studied rabies virus production (PV/BHK-21 strain) by BHK-21 cells grown at the optimal conditions determined previously. We analyzed the effects of multiplicity of infection (MOI) and type of medium used for virus multiplication in spinner-flasks and showed that the highest virus titer reached (when the cells were infected at a MOI of 0.3) in M199 medium supplemented with 0.2% of bovine serum albumin was equal to 8.2x10(7) Fluorescent Focus Units (FFU)/ml. When we grew the cells in a 2-l perfused bioreactor, we obtained a maximal virus titer of 3x10(8) FFU/ml. In addition, we scaled-up to a 20-l bioreactor and obtained similar results for cell density and virus titer. The experimental vaccine we developed meets WHO requirements for vaccine potency. Each run yielded about 40,000 doses of potent vaccine.
