We detected the distribution of lipases in 35 Aeromonas isolates by PCR andphenotypic test using tributyrin as substrate. The positive rates were 100% and 83%,respectively. The lipase activity or associated genes could be detected in the two avirulentstrains, A. hydrophila W1 and A. hydrophila 4332. It suggested that lipase might not be animportant factor in pathogenic mechanism of A.

对本实验室保存的35株气单胞菌分离株进行了脂酶的表型检测和PCR检测，结果分别为83％和100％，特别是嗜水气单胞菌无毒株W1和Ah4332也能检测到脂酶活性或基因，表明脂酶在该菌的致病机制中不是决定性因子。
