RT - Journal Article T1 - Persian bee propolis and pollen extracts enhanced the non-specific immune response of rainbow trout (Onchorhynchus mykiss) and resistance against Aeromonas hydrophila JF - IFRO YR - 2017 JO - IFRO VO - 16 IS - 2 UR - http://jifro.ir/article-1-2772-en.html SP - 654 EP - 667 K1 - Propolis K1 - Pollen K1 - Non-specific immunity K1 - Onchorhynchus mykiss AB - The effect of Persian bee propolis and pollen extracts on innate immune response of rainbow trout (Onchorhynchus mykiss) was investigated. Fish were fed diets containing 1% Pollen, 1% propolis and combination of the two immune-stimulants (0.5% Pollen and 0.5% propolis) as treatment groups and fed without the two immune-stimulants as positive and negative control groups for 4 weeks. The effects of different stimulants at different weeks (Time × stimulants) were analyzed with the Repeated Measures ANOVA. The first-four groups were then subjected to Aeromonas hydrophila for 5 days. The phagocytic activity, respiratory burst activity, Plasma Total Protein and cumulative mortality were monitored. The results showed that fish fed diet containing 1% propolos or 0.5% Pollen+ 0.5% propolis enhanced non-specific immunity including respiratory burst activity, phagocytosis but decreases the mortality in challenging with A. hydrophila by 45 and 65%, respectively.
