Protective effect of AWBE antigens against a challenge infection with 150 live <i>S. mansoni</i> cercariae in C57BL/6 mice.

1<p>Average n° of adult worms (males and females) recovered in the perfusion fluid of liver and small mesenteric veins from each experimental group (Mean ± SEM, <i>n</i> = 10).</p><p>The reduction of the parasitic load was calculated according to formula: % Protection = (1−B/A)×100 <a href="http://www.plosntds.org/article/info:doi/10.1371/journal.pntd.0002254#pntd.0002254-Shuxian1" target="_blank">[31]</a> where A is the average n° of worms in the AWBE-immunized group and, B the average n° of worms in the adjuvant (ADJ) inoculated group (Control). AW: Adult Worms; AWBE: Adult Worm <i>n</i>-Butanol Extract; ADJ: adjuvant inoculated mice; B: mice injected with buffer. Significance by <i>t</i> student test (compared to group of ADJ-inoculated animals):</p>*<p>significant (<i>p</i>≤0.05).
