The apparent infection of NA-C1300 cell cultures by nucleocapsid material of the Canadian Arctic strain of rabies virus

| Summary: | Murine neuroblastoma (NA-C1300) and baby hamster kidney (BHK-21/C13) cell cultures were infected with the Canadian Arctic strain of rabies virus. Subcultures were passed following incubation for 3 to 4 days at 35 °C. The supernatant fluids from the BHK cultures demonstrated increasing infectivity in both NA and BHK cells concomitantly with an increase in the number of parent cells staining with an anti-glycoprotein stain. On the other hand, the supernatant fluids from the NA cultures initially showed higher infectivity in NA cells than in BHK cells. This feature was related to a low production of glycoprotein-staining cells in the parent NA cultures. The reduction of infectivity in NA cells of some NA supernatant fluids (and brain suspensions) by anti-nucleoprotein antibodies suggests that nucleocapsid material is, in some manner, capable of infecting NA cells. Infectivity of this virus strain in experimental mice is also related to the production of glycoprotein and may not be correlated with the degree of infection in NA cell cultures.Key words: rabies, nucleocapsid, infection, cells. |
