  1. *: The middle ear lavage was collected at 3 and 7 days after inoculation of live bacteria to investigate the presence of live bacteria. Values are given as the number of culture positive animals/total number of animals. NS: no significant difference. 1+: 1 ~ 10 colonies, 2+: 11 ~ 20 colonies, 3+: 21 ~ 30 colonies, 4+: > 30 colonies.
