Comparison of primary skunk brain and kidney and raccoon kidney cells with established cell lines for isolation and propagation of street rabies virus

Cell cultures prepared from skunk kidney, raccoon kidney, and skunk brain were compared with CER, murine neuroblastoma (C1300, clone NA), baby hamster kidney (BHK-21, S-13), and dog kidney (MDCK) cell lines for virus isolation and propagation of street and fixed rabies virus. The skunk brain cells were suitable for efficient replication of all the virus isolates. They were comparable to CER and murine neuroblastoma cells for virus isolation and propagation. None of the other cell cultures was satisfactory. Further work is under way to refine the skunk brain cell cultures.
