Strains of Aeromonas spp. (883) were isolated from 10 stations in the north-west of Spain. Biotyping of the strains gave: 55% Aeromonas caviae, 34% A. hydrophila, 6% A. sobria and 5% Aeromonas spp. Phenotypic characters that have been claimed to be related to virulence such as haemolysis and the Voges-Proskauer reaction were detected mostly in A. hydrophila and A. sobria. The distribution of the species was significantly related to levels of faecal pollution in waters. Aeromonas caviae predominated in sewage and waters with a high degree of faecal pollution. In less polluted waters, either fresh or marine, A. caviae and A. hydrophila were almost equally distributed. In waters with low or no faecal pollution, the proportion of A. sobria to other species increased considerably.
从西班牙西北部的10个站点分离出了气单胞菌属菌株（883株）。对这些菌株进行生物分型得到：55%为豚鼠气单胞菌，34%为嗜水气单胞菌，6%为温和气单胞菌，5%为气单胞菌属其他种。一些被认为与毒力相关的表型特征，如溶血和Voges-Proskauer反应，大多在嗜水气单胞菌和温和气单胞菌中检测到。这些菌种的分布与水体中的粪便污染水平显著相关。豚鼠气单胞菌在污水和粪便污染程度高的水体中占主导地位。在污染程度较低的水体中，无论是淡水还是海水，豚鼠气单胞菌和嗜水气单胞菌的分布几乎相等。在粪便污染程度低或无污染的水体中，温和气单胞菌相对于其他菌种的比例大幅增加。
