The present study investigated the therapeutic effects of turmeric on the health of rohu (Labeo rohita) challenged with pathogenic Aeromonas veronii. The fish were fed on diets supplemented with different levels of turmeric for 120 days and then challenged with pathogenic A. veronii for 2 weeks, during which fish continued to receive respective turmeric-supplemented diets. Following trial, serum immune parameters and histomorphology of tissues including the intestine, liver, kidney, and gills were examined. The study showed severe effect of A. veronii in TM0 (positive control, basal diet without turmeric, and bacteria injected) treatment compared to TMN (negative control, basal diet without turmeric, and no bacteria injected). The treatments from TM5-TM20 (turmeric-supplemented feed at 5–20-g/kg feed with bacterial injection) showed less intensity of disease symptoms and significantly increased immune response with the increase in turmeric supplementation compared to TM0. In addition, the disease symptoms at tissue histomorphology decreased as the turmeric supplementation increased. Highest supplementation of turmeric (20 g/kg feed) showed reduced bacterial pathogenicity by maintaining nearly normal micro architecture of tissues compared to other turmeric-supplemented groups. The study concludes that A. veronii can infect L. rohita and can cause mortality unless proper preventive measures are practiced. Therefore, supplementation of turmeric could be recommended in aquaculture systems through feed to prevent disease impact.

本研究研究了姜黄对致病性气单胞菌感染的芜菁（Labeo rohita）的治疗作用。将鱼饲喂补充有不同水平姜黄的饲料120天，然后用病原性维氏假单胞菌攻击2周，在此期间，鱼继续接受各自补充姜黄的饲料。试验后，检查了血清免疫参数和包括肠，肝，肾和g在内的组织的组织形态。该研究表明维罗纳芦荟的严重影响与TMN（阴性对照，无姜黄的基础饮食，无细菌注射）相比，TM0（阳性对照，无姜黄的基础饮食，有细菌注射）治疗。与TM0相比，TM5-TM20（以5-20 g / kg细菌注射添加姜黄补充饲料，经细菌注射）的处理显示出较低的疾病症状强度，并且随着姜黄补充剂的增加，免疫反应显着增强。另外，随着姜黄补充剂的增加，组织组织学上的疾病症状减少。与其他补充姜黄的组相比，补充最多的姜黄（20 g / kg饲料）显示出通过保持几乎正常的组织微观结构而降低了细菌致病性。该研究的结论是A.维罗纳能感染L.野鲮除非采取适当的预防措施，否则可能导致死亡。因此，建议在水产养殖系统中通过饲料补充姜黄，以防止疾病影响。
