Host Organism : CRFK cells (ATCCCCL-94) feline cell cultures
Incubation : Temperature: 37.0°C Duration: 7 days
Effect : Yes, in vitro effects: Cytopathic effects (syncytium formation and sloughing)
Comments : Produces giant cells most effectively upon transfer/split of inoculated cells. Syncytia formation more dramatic in fibroblastic cells rather than CRFK. Freeze-labile when not frozen with 10% DMSO. Produces giant cells most effectively upon transfer/split of inoculated cells. Syncytia formation more dramatic in fibroblastic cells rather than CRFK.
