BALF neutrophil percentage.

<p>(<b>A</b>, <b>B</b>, <b>C</b> and <b>D</b>) Inoculation with rough morphotype causes greater BALF neutrophil percentage than smooth morphotype at 14 days post-inoculation in CF mice (<b>D</b>). Red circles indicate smooth morphotype inoculation with conversion to rough morphotype. Minimal BALF neutrophilia was seen after sterile thrombin/fibrinogen inoculation. (N = 9–20 mice in each <i>M</i>. <i>abscessus</i> group, N = 3–8 mice in each sterile group). * p< 0.05. Data displayed as mean ± SEM of group, pooled from 2–3 replicate experiments for each morphotype.
