Table 1 PRRS virus isolation efficiency from swine samples using SJPL cells compared to MARC-145 cells

From: Identification of a new cell line permissive to porcine reproductive and respiratory syndrome virus infection and replication which is phenotypically distinct from MARC-145 cell line

  1. aThe PRRSV was quantified as previously described using a real-time PCR assay [67].
  2. bThe virus isolation were attempted with both cell lines using the same swine tissue homogenates.
  3. cThree cases out of 7 were real-time PCR negative for the presence of PRRSV.
