Summary
Two different cell populations, high- (MARC-145) and low-permissive cell clones (L-1) to porcine reproductive and respiratory syndrome (PRRS) virus, were derived from MA-104 cell line (parent cell: P) by cell cloning. Maximum virus yields in MARC-145, P, and L-1 cell clones were 108.5, 103.5, and 102.5 tissue culture infective dose 50 (TCID50)/0.1 ml, respectively. The MARC-145 cell clone supported replication of all 11 different porcine reproductive and respiratory syndrome virus isolates that were tested. These results indicated that the MARC-145 cells will be useful for PRRS virus replication.
