title: Infection of rabbits with Sendai virus.
abstract: Rabbits were either inoculated with Sendai virus (SV), strain MN, or caged with virus-inoculated rabbits on the same day of the viral inoculation, and examined for viral shedding and detection of viral antigens in the respiratory tract, histopathologic changes, and serum antibodies. Infectious virus was recovered from nasal swabs at postinoculation day (PID) 3 and disappeared by PID 10. Viral antigens were detected by immunofluorescence in epithelial cells of the nasal cavities, but not of the trachea and lungs from PID 3 to PID 10, and antibodies were detected after PID 7. Rabbits had no clinical manifestations and only exhibited a moderate increase in goblet cells of the nasal epithelium. In the transmission study, virus was recovered from one of three uninoculated rabbits at postexposure day (PED) 10 and antibodies were detected at PED 15 in the same rabbit. These data suggest that, although viral multiplication was limited to the nasal epithelium, laboratory rabbits are susceptible to Sendai virus infection.
