This study aimed to assess the effect of oral administration of Synechococcus sp. PCC 7942 harboring vp19, vp28, and vp(19 + 28)against infection by white spot syndrome virus (WSSV) on juveniles of Litopenaeus vannamei. L. vannamei was orally administrated by feeding with different mutants of Synechococcus for 10 days, and then challenged with WSSV. The cumulative mortality of vp19, vp28, vp (19 + 28) groups was lower than that of the positive control group (57.8%, 62.2%, 71.1%, respectively); vp (19 + 28) group had a better protection rate than vp19 and vp28 groups. The analysis of shrimp immunological parameters showed that, after WSSV injection, the activity of superoxide dismutase, phenol oxidase, catalase, and lysozyme in the hepatopancreas of vp19, vp28, and vp (19 + 28) groups was higher than in the positive group; at the same time, growth performances of L. vannamei of experimental groups were better than control groups. Results showed that the Synechococcus mutants harboring vp19, vp28, and vp (19 + 28) could be used both as drug and feed to also enhance the defensive ability of juvenile shrimp against WSSV infection by increasing the activity of immune related enzymes.

Synechococcus sp。的作用 携带vp19，vp28和vp（19 + 28）的PCC 7942对凡纳滨对虾（Litopenaeus vannamei）感染WSSV的存活和免疫反应具有影响。
这项研究旨在评估口服Synechococcus sp。的效果。携带vp19，vp28和vp（19 + 28）的PCC 7942对抗白斑综合症病毒（WSSV）在凡纳滨对虾（Litopenaeus vannamei）少年身上的感染。通过饲喂不同的Synechococcus突变体进行10天的口服口服南美白对虾，然后用WSSV攻击。vp19，vp28，vp（19 + 28）组的累积死亡率低于阳性对照组（分别为57.8％，62.2％，71.1％）；vp（19 + 28）组的保护率高于vp19和vp28组。对虾免疫学参数的分析表明，注射WSSV后，vp19，vp28和vp（19 + 28）组肝胰腺中超氧化物歧化酶，酚氧化酶，过氧化氢酶和溶菌酶的活性高于阳性组。与此同时，实验组南美白对虾的生长性能优于对照组。结果表明，带有vp19，vp28和vp（19 + 28）的Synechococcus突变体既可以用作药物也可以用作饲料，还可以通过提高免疫相关酶的活性来增强对虾对WSSV的防御能力。
