Fewer clones disseminate when the library only has 10% of the population produce LF.

<p>There are fewer clones that disseminate when LF-producing bacteria are reduced by 90% in the inoculum. The number of clones that disseminated to the kidneys were enumerated and compared between the libraries. Each symbol represents a mouse. Bars represent the mean and error bars represent the standard deviation. Asterisks represent a statistical difference between the means (Student's T Test, *<i>P</i>-value = 0.044).
