Occlusion body yield (OB/g) from infected early L4 larvae harvested at 14 days post-infection depending on three purification methods low-speed centrifugation (LSC), sucrose gradient ultracentrifugation (SGU), and sucrose cushion centrifugation (SCC); n and N give the number of independent repetition the number of the tested larva, respectively. Vertical bars indicate the 95% confidential limits. Comparison of means using Student t test: Means with different letters (a, b and c) are significantly different at P < 0.05
