Percent infected erythrocytes and PCV in animals over time during challenge.

<p>The means of the percent infected erythrocytes (A) or PCV (B) for each group of animals are plotted by days post challenge. The AM854/AM936 vaccinates developed a statistically significantly higher percent of infected erythrocytes than the outer membrane vaccinates (p = 0.018). The differences in PCV were not statistically significant.
