| 摘 要： | 暴发性鱼病流行季节及非发病季节的健康草鱼肠道气单胞菌的分布调查表明，两季中气单胞菌占总菌数的比例变化不大，只是冬季前肠道的气单胞菌比例明显增高，应视为草鱼肠道的正常寄生菌落。部分胞外酶中发现了较多产木聚糖酶的气单胞菌。

| Abstract: | The distributions of Aeromonas in intestines of healthy grass carp (Ctenopharyngodon idella) in epidemic and non- epidemic seasons of outbreaking fish diseases are discussed in this paper.The results show that no difference was found in Aeromonas -bcteria ratio in the samples between the 2 seasons. The Aeromonas -bcteria ratio of the samples from the epidemic season increased in winter. It can be inferred that the intestinal Aeromonas is a normal part of the intestinal microflora in grass carp. And in the exoenzyme some more Aeromonas were found, which can produce xylanase. |
