A DNA-DNA hybridization study was carried out to determine the taxonomic position of a new group of enterobacteria (group H2) previously studied by numerical taxonomy. All the strains of this group revealed relatively high reassociation binding ratios with the centrotype; 82% of the strains of the group showed more than 69% of reassociation with the centrotype. In spite of numerical taxonomy conclusions, there was no genetic relationship with the species Enterobacter cloacae (higher reassociation binding ratio: 37%). No significant genetic relationship with the other groups of enterobacteria was found. Rahnella aquatilis was defined from phenotypic and genetic data. The strain 133 (CIP 78-65) is proposed as type strain of the species.
进行了一项DNA-DNA杂交研究，以确定先前通过数值分类法研究的一组新的肠杆菌（H2组）的分类地位。该组所有菌株与中心型显示出相对较高的重结合比率；该组82%的菌株与中心型的重结合率超过69%。尽管有数值分类法的结论，但与阴沟肠杆菌没有遗传关系（较高的重结合比率：37%）。未发现与其他肠杆菌组有显著的遗传关系。根据表型和遗传数据定义了水生拉恩菌。菌株133（CIP 78-65）被提议作为该物种的模式菌株。
