Comparison of biofilm formation.
Following 48 h incubation on a polystyrene 96-well plate surface in brain-heart infusion broth, the average absorbance (OD595) obtained with the crystal violet assay was evaluated and compared between strains from multiple positive blood cultures (n = 25), single positive blood culture (n = 26), and non-blood isolates (n = 23). Non-blood samples were obtained from peritoneal fluid (n = 2), peritoneal dialysate (n = 1), ear discharge (n = 2), pleural fluid (n = 1), urine (n = 6), endotracheal aspiration (n = 1), and open wounds (n = 10). One-way ANOVA with post-hoc analysis was used to compare the means of three continuous variables.
