Relative mean hemolysis of sheep erythrocytes following exposure to bacterial supernatants.

Each supernatant at the indicated concentrations, in addition to PBS, THY, and saponin, is listed on the x-axis. The y-axis indicates relative viability after adjustment to a scale of 100 as described in the materials and methods. Error bars indicate standard deviation. Indicators of significant differences (described in the results) are not depicted to enhance figure clarity. Data represent the averages obtained from at least 2 independent experiments.
