title: The role of maternal antibody in contact infection of mice with Sendai virus.
abstract: To study the role of maternal antibody in infection with Sendai virus in mice, maternally immune and non-immune mice, aged 4 to 5 weeks, were placed in cages with infector mice and the cages were kept for 19 days in a vinyl isolator. Neither increase of hemagglutination inhibiting antibody titers nor gross pulmonary lesions was recognized on the immune mice during the observation period in contrast with the non-immune mice. However, the multiplication of the virus in their respiratory tracts was the same or slightly low as compared with that of non-immune mice.
