CFUs recovered from nasopharyngeal washes of CD1 outbred mice inoculated intranasally singly with serotype 23B MT93 or MT23 (a), singly with serotype 38 MT120 or MT28 (b). In c CFUs from a competition experiment with a 1:1 ratio of serotype 38 MT120 and MT28, seven days post inoculation, are transformed into the competitive index. Six mice were used for each condition. All p-values derived using Wilcoxon ranked-sum test: a p-value = 0.7. b MTs 120 and 28 p-value = 0.06; c MTs 93 and 23 p-value < 0.001. All p-values reported are for two-sided statistical tests.
