It was demonstrated that the transmission S. pneumoniae in guinea pigs was remarkably promoted by the combined infection with Sendai virus in the following experiments. When guinea pigs infected with S. pneumoniae alone (infector) were cagemated with non-treated guinea pigs (contact) for 2 and 4 weeks, only 2 of 30 contacts were infected with the organism. On the contrary, when the contact guinea pigs were infected with Sendai virus and immediately cage-mated with the infectors, the pneumococcal infection occurred in 25 of 30 contacts during 2 to 4 weeks period. In the experiment in which 30 non-treated contacts were cage-mated with pneumococcal infectors for 4 weeks and then infected with Sendai virus, no pneumococcal infection was demonstrated in the contacts, suggesting no presence of latent infection of the organism in the contact guinea pigs. Twenty-five of 30 contacts suffered from pneumococcal infection when they were exposed to Sendai virus for 2 weeks and then cage-mated with infectors. The multiplication of S. pneumoniae in the respiratory tract of the guinea pigs was remarkably enhanced by combined infection with Sendai virus. Namely, a 1000-fold increase in the number of organism resulted in the guinea pigs suffered from combined infection as compared with that in the animals received pneumococcal single infection.
