During the period from October 1982 to July 1984, a total of 1,157 specimens that consisted of 132 river and lake water, 514 river and lake muds, and 511 fresh-water fish caught in both Tama River and Sagami River were examined the presence of the organisms. Of them, 132 (100%) river and lake waters, 304 (59.1%) river and lake muds, and 462 (90.4%) intestinal contents of fresh-water fish were found to have harbor a mean concentration of 1.3 x 10(3)/l, 1.6 x 10(6)/g, and 1.1 x 10(6)/g of motile-Aeromonas respectively. However, nonseasonal variation was observed in the incidence of the organisms throughout the period of investigation. When attempts were made to classify the isolates by the method described Popoff et al., 17 (14.2%) of 120 water-isolates were typed as A. hydrophila, 33 (27.5%) as A. sobria and 35 (29.2%) as A. caviae respectively. And the rest of the 35 (29.2%) remained untypable. As for the 176 mud-isolates, 38 (21.6%) were typed as A. hydrophila 23 (13.1%) as A. sobria and 41 (23.3%) as A. caviae respectively. And the rest of 74 (42.0%) remained untypable. Some efforts were made on the 1,056 strains obtained from fresh-water fish, and 182 (17.2%) were typed as A. hydrophila, 332 (31.4%) as A. sobria and 206 (19.5%) as A. caviae respectively. And the rest of the 336 (31.8%) remained untypable.
在1982年10月至1984年7月期间，对总共1157份标本进行了检查，以确定其中是否存在相关生物，这些标本包括132份河流和湖泊水、514份河流和湖泊淤泥，以及511条从多摩川和相模川捕获的淡水鱼。其中，132份（100%）河流和湖泊水、304份（59.1%）河流和湖泊淤泥以及462份（90.4%）淡水鱼的肠道内容物中分别发现含有平均浓度为1.3×10³/升、1.6×10⁶/克和1.1×10⁶/克的运动性气单胞菌。然而，在整个调查期间，观察到这些生物的发生率没有季节性变化。当尝试按照波波夫等人描述的方法对分离株进行分类时，120份水分离株中有17份（14.2%）被鉴定为嗜水气单胞菌，33份（27.5%）为温和气单胞菌，35份（29.2%）为豚鼠气单胞菌。其余35份（29.2%）仍无法分型。对于176份淤泥分离株，38份（21.6%）被鉴定为嗜水气单胞菌，23份（13.1%）为温和气单胞菌，41份（23.3%）为豚鼠气单胞菌。其余74份（42.0%）仍无法分型。对从淡水鱼中获得的1056株菌株也进行了一些分类工作，其中182份（17.2%）被鉴定为嗜水气单胞菌，332份（31.4%）为温和气单胞菌，206份（19.5%）为豚鼠气单胞菌。其余336份（31.8%）仍无法分型。
