Figure 1From: Biofilm formation by nontypeable Haemophilus influenzae: strain variability, outer membrane antigen expression and role of piliBiofilm formation by clinical isolates of nontypeable H. influenzae. Bars represent the means of three independent experiments performed in quadruplicate. Error bars represent standard deviation. Y axis is optical density at 570 nm. la: middle ear isolates: a. 83; b. 955; c. 1128; d. 1749; e. 1826; f. 2536; g. 2846; h. C4556; i. 8131; j. 8183; k. 8981; 1. 9289; m. C1425; n.
