PG - 135-49 LID - 10.1023/A:1008022828736 [doi] AB - Veterinary viral vaccines generally comprise either attenuated or chemically inactivated viruses which have been propagated on mammalian cell substrates or specific pathogen free (SPF) eggs. New generation vaccines include chemically inactivated virally-infected whole cell vaccines. The NM57 cell line is a bovine nasal turbinate persistently infected (non-lytic infection) with a strain of the respiratory syncytial virus (RSV). The potential of microcarrier technology for the cultivation in bioreactors of this anchorage dependent cell line for RSV vaccine production has been investigated. Both Cytodex 3 and Cultispher S microcarriers proved most suitable from a selection of microcarriers as growth substrates for this NM57 cell line. Maximum cell densities of 4.12x105 cells ml-1and 5.52x105 cells ml-1 respectively were obtained using Cytodex 3 (3 g l-1) and and Cultispher S (1 g l-1) in 5 l bioreactor cultures. The fact that cell growth was less sensitive to agitation rate when cultured on Cultispher S microcarriers, and that cells were efficiently harvested from this microcarrier by an enzymatic method, suggested Cultispher S is suitable for further evaluation at larger bioreactor scales (>5 l) than that described here.
