对来自不同临床和环境来源的147株气单胞菌进行Popoff和贝隆生物分型。在147株生物分型的分离株中，可鉴定出137株（93%），其中嗜水气单胞菌占主导地位（48%），其他两个种（温和气单胞菌和豚鼠气单胞菌）的百分比相等（25 - 27%）。一些额外的生化特性被发现与这三个物种中的一个或多个显着相关。这些包括赖氨酸脱羧酶活性、绵羊红细胞的溶血、卵磷脂酶产生、葡萄糖分解活性、熊果苷水解和利用各种碳水化合物产生酸。通过将这些表型特性纳入扩展的生物分型系统，98%的分离株被确定。注意到个别物种在某些身体部位的选择性分布。
A group of 147 Aeromonas isolates from diverse clinical and environmental sources was subjected to the biotyping scheme of Popoff and Veron. Of the 147 isolates biotyped, 137 (93%) could be identified, with Aeromonas hydrophila predominating (48%) and equal percentages (25 to 27%) of the other two species (Aeromonas sobria and Aeromonas caviae). A number of additional biochemical properties were found to be significantly associated with one or more of these three species. These included lysine decarboxylase activity, hemolysis of sheep erythrocytes, lecithinase production, staphylolytic activity, arbutin hydrolysis, and acid production from utilization of various carbohydrates. By incorporating these phenotypic properties into an extended biotyping system, 98% of the isolates were identified. Selective distribution of individual species with respect to certain body sites was noted.
