Biofilm formation by <i>Acinetobacter.</i>

<p>Biofilm formation after 24 h at 28°C for the clinically relevant <i>A. baumannii</i> (n = 45), <i>A.</i> gen. sp. 3 (n = 3) and <i>A.</i> gen. sp. 13TU (n = 3) and for the clinically less-relevant <i>A. calcoaceticus</i> (n = 3) and <i>A. junii</i> (n = 7). Data are expressed as mean biofilm mass (in arbitrary units (a.u.)) of three independent experiments; each performed in sixplicate. Outbreak-associated (+) or non-outbreak-associated (−) isolate. European clone I (I), II (II) or III (III) isolate. Multidrug resistant (MDR; +) or susceptible (−) isolate.
