A comparative study of the bacterial flora of the water of Chesapeake Bay and Tokyo Bay was undertaken to assess similarities and differences between the autochthonous flora of the two geographical sites and to test the hypothesis that, given similarities in environmental parameters, similar bacterial populations will be found, despite extreme geographic distance between locations. A total of 195 aerobic, heterotrophic bacterial strains isolated from Chesapeake Bay and Tokyo Bay water were examined for 115 biochemical, cultural, morphological, nutritional, and physiological characters. The data were analyzed by the methods of numerical taxonomy. From sorted similarity matrices, 77% of the isolates could be grouped into 30 phena and presumptively identified as Acinetobacter-Moraxella, Caulobacter, coryneforms, Pseudomonas, and Vibrio spp. Vibrio and Acinetobacter species were found to be common in the estuarine waters of Chesapeake Bay, whereas Acinetobacter-Moraxella and Caulobacter predominated in Tokyo Bay waters, at the sites sampled in the study.
对切萨皮克湾和东京湾水域的细菌群落进行了一项比较研究，以评估这两个地理位置的本地菌群之间的异同，并检验以下假设：尽管两地地理位置相距甚远，但鉴于环境参数相似，仍会发现相似的细菌种群。从切萨皮克湾和东京湾水域分离出总共195株需氧、异养细菌菌株，检测了它们的115种生化、培养、形态、营养和生理特征。采用数值分类法对数据进行分析。从分类后的相似性矩阵来看，77%的分离株可归为30个类群，并初步鉴定为不动杆菌-莫拉菌属、柄杆菌属、棒状杆菌属、假单胞菌属和弧菌属。在该研究采样的地点，弧菌属和不动杆菌属在切萨皮克湾的河口水中很常见，而不动杆菌-莫拉菌属和柄杆菌属在东京湾水域占主导地位。
