Cell wall thickness of <i>A</i>. <i>fumigatus</i> in the single and mixed biofilms.

<p>(<b>A</b>) Observation on 24 h–old single <i>A</i>. <i>fumigatus</i> biofilm (1–2) and mixed biofilm (3–4) by TEM (<b>B</b>) Cell wall thickness of <i>A</i>. <i>fumigatus</i> measured on TEM images of the single and mixed biofilms. H = hyphae, B = bacteria, CW = cell wall, ECM = extracellular matrix, Sm = <i>S</i>. <i>maltophilia</i>, Af = <i>A</i>. <i>fumigatus</i>. For each biofilm, approximately 15 measurements on 27 hyphae were taken. Results are expressed in mean±SE, * <i>p</i> < 0.0001.
