Replication of classical swine fever virus strains and isolates in different porcine cell lines.

Classical swine fever virus (CSFV) is an economically important pathogen of domestic pigs and wild boar. Due to the highly variable clinical picture of CSF, laboratory methods are essential for an unambiguous diagnosis. Virus isolation using cell culture is still considered the gold standard. It is based on the incubation of permissive cells with organ or leukocyte preparations followed by antigen detection. In the "EU Diagnostic Manual for CSF Diagnosis", the permanent cell line PK(15) (porcine kidney) is recommended. In the European Reference Laboratory (EURL) a clone of this cell line, PK(15)A, and the STE (swine testicular epitheloid) cell line are in use for propagation of CSFV. The aim of this work was to assess the relative ability of eleven permanent cell lines derived from various organs of wild boar and domestic pig, respectively, to support the replication of different strains and isolates in comparison to these cell lines. An avirulent and a highly virulent laboratory CSFV strain, and several recent field isolates from domestic pigs and wild boars were used. Titers were determined after one, two and three virus passages, and after 48 and 120 h of incubation. Of the eleven cell lines analyzed, two were found that replicated all the tested CSFV strains and field isolates. Those may be useful for improving diagnosis of CSFV and for preparing low-passaged virus stocks of new isolates.[1]
