Biofilm formation among the 50 isolates of <i>Acinetobacter</i> spp. in microtiter plates.

<p>Strain numbers are designated in x axis. About 60% of the isolates significantly forms biofilms when incubated for prolonged hours. Data are pooled from triplicate experiments. The results are expressed as the mean and the error bars indicate the standard deviation. The <i>P</i> value was less than 0.05 (<i>P</i><0.05).
