  • a Mice were infected with 1,500 IFU ofC. trachomatis MoPn intravaginally on day −60 relative to the pulmonary challenge.

  • b Mice were challenged with 400 IFU of MoPn by intratracheal inoculation.

  • c Mean numbers of IFU ± standard errors detected in tissues collected 11 days after pulmonary challenge.
