  • a In each case the percentage of the opaque phase is 100% minus the percentage of the transparent phase.

  • b The Students t test was used for TIGR4, EF3030, and BG7322, the Fisher exact test was used for L82016.

  • c For 13 mice the nasal wash bacteria were >90% transparent, and for 13 mice the nasal tissue bacteria were <90% transparent. The L82016 data were calculated from a pool of the data from experiments 5, 6, and 7, as shown in Tables 1 and 2.
