Plaque reduction viral neutralization by anti-M2e antibodies.

<p>The neutralization capability of sera obtained from chickens vaccinated with PBS (mock), M2eP-2x (anti-M2e), and H7N2 (anti-H7N2) or H5N2 (anti-H5N2) immune sera was tested against H7N2 (A) and H5N2 (B) viruses. Each bar indicates the mean plaque reduction percentage of each sample ± standard error of mean. Asterisk indicate the statistical significance at <i>p</i>< 0.05(*), <i>p</i> < 0.001 (***) between mean plaque reduction percentage as determined with one way ANOVA followed by LSD post-hoc test.
