Enhanced replication of porcine circovirus type 2 (PCV2) in a homogeneous subpopulation of PK15 cell line.
Virology. 2007 Dec 20; 369(2):423-30.V

Abstract

Post-weaning multi-systemic wasting syndrome (PMWS) has emerged as a major disease that poses a significant threat to the economics of global swine industry. Porcine circovirus type 2 (PCV2) is the causal agent of PMWS in pigs. Currently, the prevention of PCV2 infection based on vaccines is limited, and the available vaccines are either killed viral vaccines or recombinant protein based vaccines and not cost effective. The PK-15 cells, which is widely used for PCV2 propagation, is not efficient and heterogeneous in terms of permissivity to viral infection. In order to acquire a homogeneous porcine kidney cell line that can reliably produce PCV2 in high titers, cell clones that show high- (PK15-C1) or low-permissive (PK15-A2) phenotype to PCV2 infection were derived from heterogeneous PK15 parent cells by limiting dilution and cell cloning. Maximum virus titers in PK15-C1, PK15-A2 and PK15 parent cells were 10(8), 10(2) and 10(5) tissue culture infective dose 50 (TCID 50)/ml, respectively. The viral proteins of PCV2 were produced and accumulated faster in PK15-C1 cells than those in PK15 parent cells. These results indicate that PK15-C1 cell clone is more permissive to PCV2 infection than PK15 parent cells and thus will be useful for PCV2 replication in vitro, as well as, vaccines, diagnostic and research applications on PCV2.
