Neobenedenia melleni-Specific Antibodies Are Associated with Protection after Continuous Exposure in Mozambique Tilapia

Figure 3

Effects of continuous exposure on specific antibody levels in tilapia mucus and plasma at 45, 102, and 120 days postexposure (DPE) and unexposed fish (0 DPE) as determined by ELISA and represented by optical density (405 nm). Mucus and plasma samples were diluted 1 : 3 and 1 : 2000 in PBS, respectively. Vertical bars indicate mean ± SEM. ^*Significantly different from antibody levels in mucus of 0 DPE and 45 DPE groups at ; ^**significantly different from antibody levels in plasma of 0 DPE groups at (one-way ANOVA and Student’s test). Blood samples were not collected at 45 DPE.
