Distribution of <i>in vitro</i> rhamnolipid production in <i>P. aeruginosa</i> isolates from CF patients at different stages of lung infection.

<p>The box and whisker plots represent the median (thick line inside the box), 10, 25, 75 and 90 centiles of the <i>in vitro</i> rhamnolipid production (µg/ml) of <i>P. aeruginosa</i> isolates from intermittently colonized and chronically infected patients; Mann-Whitney test was used to investigate the significance of the difference between the groups.</p>
