1灿烂弧菌对厚壳贻贝免疫指标和消化酶活性的影响显示文摘为探究灿烂弧菌对厚壳贻贝免疫指标和消化酶活性的影响,用1×10~6、1×10~7、1×10~8个/mL 3个浓度的灿烂弧菌刺激厚壳贻贝,探讨弧菌刺激后厚壳贻贝的一氧化氮合酶(NOS)、一氧化氮(NO)、超氧化物歧化酶(SOD)、丙二醛(MAD)等免疫指标和淀粉酶、蛋白酶等消化酶的变化情况。结果显示,灿烂弧菌刺激48 h后,厚壳贻贝足、鳃、消化腺等组织中仅消化腺的NOS活性较对照组有显著升高,且酶活性随初始细菌浓度的升高而升高,故选用消化腺来测定灿烂弧菌刺激后72 h内的免疫指标和消化酶活性的变化。灿烂弧菌刺激后,48 h内NOS活性较对照组均显著升高。NO含量较对照组均显著升高,与NOS显现相同变化趋势。SOD活性在各浓度灿烂弧菌刺激下较对照组均显著升高,而MAD含量在实验组中含量显著低于对照组。淀粉酶活性在实验组中显著低于对照组,总体呈现先下降后升高的趋势。蛋白酶活性在各实验组中均呈现先升高后下降的趋势。研究表明,灿烂弧菌对厚壳贻贝免疫指标和蛋白酶活性的升高有诱导作用,但对蛋白酶的活性有抑制作用。本研究初步探明了厚壳贻贝对灿烂弧菌的免疫应答机制,为进一步研究灿烂弧菌和厚壳贻贝相互作用机制以及厚壳贻贝免疫机制奠定了基础。梁箫 张亚 刘钰珠 李一峰 BATISTA M F POWER D 杨金龙 2018水产学报2018,42,9:5
