摘　　要：为探讨鱼腥草对人工感染维氏气单胞菌锦鲤鳃部部分免疫指标的影响,选取锦鲤96尾随机分两组,C组锦鲤投喂添加6‰鱼腥草的饲料,K组投喂基础日粮作为对照。分别饲养14 d后空腹24 h,通过腹腔进行人工感染维氏气单胞菌,于0、1、2、4 d进行采样,检测鳃部的炎性因子(Il-4,Il-10)和免疫球蛋白(Ig T)。结果表明:K组四个时间段IL-4、IL-10和IgT含量差异均不显著(P>0.05);C组IL-4含量1 d和2 d时显著高于0 d、4 d(P<0.05),且高于K组;IL-10含量1,2,4 d时显著高于0 d(P<0.05),且均高于K组;IgT含量1 d与2 d高于4 d且显著高于0 d(P<0.05),且1 d与2 d时C组高于K组。说明前期鱼腥草饲养对细菌感染锦鲤鳃部免疫具有一定的提升作用。To investigate the effects of Houttuynia cordata Thunb on some immune indexes in the gill of Koi carp artificially infected with Aeromonas veronii,ninety-six koi were randomly divided into two groups.Group C was fed with the diet supplemented with 6‰Houttuynia cordata Thunb,and group K was fed with the basal diet as the control.After 14 days of feeding,Aeromonas veronii was artificially infected through the abdominal cavity on an empty stomach for 24 h.Samples were collected at 0,1,2,4 days to detect inflammatory factors(Il-4,Il-10)and immunoglobulin(IgT)in the gill.The results showed as follows:there were no significant differences in the contents of IL-4,IL-10 and IgT in group K at four time periods(P>0.05).IL-4 content in group C was significantly higher than that in group 0 and 4 at 1 and 2 days(P<0.05),and was higher than that in group K;IL-10 contents at 1,2 and 4 d was were significantly higher than that at 0 d(P<0.05),and was higher than that in K group.The IgT content at 1 d and 2 d was higher than that at 4 d and was significantly higher than that at 0 d(P<0.05)and the IgT content in group C was higher than that in group K at 1 d and 2 d.These results indicated that Houttuynia cordata Thunb feeding could improve the gill immunity of bacterial infected koi carp.
