摘    要:给不同组草鱼分别投喂含0%、0.5%、1%和2%穿心莲的人工配合饲料,在不同时期取样检测各组草鱼前、中、后肠需氧和兼性厌氧菌的种类和数量。结果显示,草鱼肠内细菌的种类,特别是优势菌群的种类没有受到穿心莲的影响。各组草鱼肠内各部位的优势菌群均为气单胞菌Aeromonas和肠杆菌Enterobacteriaceae。草鱼肠内细菌数量为105~108CFU·g-1,分析后发现,各组草鱼肠内细菌数量之间没有显著差异(P>0.05)。但1%及2%的穿心莲能降低气单胞菌的组成。上述结果表明,一定浓度的穿心莲可以通过降低优势菌群气单胞菌的组成而对草鱼肠内微生态系产生影响。

关 键 词:草鱼  穿心莲  肠内细菌  抑菌作用

Abstract:During being fed upon the feeding stuff containing 0% 0. 5% .1 % and 2% the Creat, Andrographis paniculata (Burm F.) Nees, respectively , the bacterial flora in the intestines of grass carp (Ctenopharyngodon idellus) was examined both qualitatively and quantitatively. The results showed that the species of the intestinal bacteria, especially the species of the predominant microflora had no change. The predominant microflora of each region of the intestine was Aeromonas and Enterobacteriaceae. The number of the intestinal bacteria was 10~5- 10~8 CFU per gram (wet weight of intestine plus contents) and there was no significant difference (P >0.05) among the different grass carp groups. However, both 1% and 2% the Creat could partly inhibit the growth of the predominant microflora Aeromonas. The results above indicated that the Creat in certain concentration could affect the microflora system in the intestine of grass carp by partly inhibited the growth of the predominant bacteria Aeromonas.
Keywords:Ctenopharyngodon idellus  Andrographis paniculata  intestinal microflora
