Immunofluorescence for detection of viral antigen in mice infected with Sendai virus.
Sendai virus infection transmitted by contact from cagemates was followed by virus titration and immunofluorescence. The virus grew in the respiratory tract and caused macroscopic lesions in all contact mice. The virus grew to a higher titer in the lung than in the trachea. Tracheal smears, however, were found to be the most suitable for the diagnosis of Sendai virus infection by immunofluorescence, since they contained a large number of cells with intense fluorescence. Diagnosis of Sendai virus infection was made by immunofluorescence within a few hours after autopsy made at early stages of infection.
