FIG. 1.

Role of CPS in the resistance to antimicrobial peptides and proteins. Survival of bacteria (percentage of colony counts of cells not exposed to the agents) with different amounts of HNP-1 (A), HBD1 (B), lactoferrin (C), protamine sulfate (D), and polymyxin B (E). Each point represents the mean and standard deviation of eight samples from four independently grown batches of bacteria, and significant survival differences between 52145 and 52K10 are indicated by asterisks. Symbols: •, K. pneumoniae 52145; ▵, K. pneumoniae 52O21; ○, K. pneumoniae 52K10.
