1972年5月，在切萨皮克湾进行了一项海湾范围内的副溶血性弧菌分布调查，以确定在切萨皮克湾的罗德河子河口观察到的副溶血性弧菌的年度循环是否发生在切萨皮克湾的其他地方。在早期的一项研究中，4月至6月初，当水温从14摄氏度上升到19摄氏度时，被发现是罗德河生物年周期的关键时期，因为这是年周期开始的时间段。然而，这项研究的结果表明，在1972年5月期间，在水柱中未发现副溶血性弧菌。尽管如此，几个沉积物和浮游生物样本产生了副溶血性弧菌分离株。与早期副溶血性弧菌年循环研究中检查的罗德岛河地区数据的比较表明，开阔海湾中副溶血性弧菌年循环的启动时间可能受到温度和盐度等各种因素的影响，即，较深水域的副溶血性弧菌年周期的开始可能晚于浅水区。使用数值分类法确认研究样品中存在微生物，分析中还包括19种参考菌株。
A Bay-wide survey of the distribution of Vibrio parahaemolyticus was carried out in Chesapeake Bay during May 1972, to determine whether the annual cycle of V. parahaemolyticus which was observed to occur in the Rhode River subestuary of Chesapeake Bay took place in other parts of Chesapeake Bay. In an earlier study, April to early June, when the water temperature rises from 14 to 19 C, was found to be a critical period in the annual cycle of the organism in the Rhode River, since this is the time period when the annual cycle is initiated. Results of this study, however, revealed that V. parahaemolyticus could not be found in the water column during May 1972. Neverthless, several samples of sediment and plankton yielded V. parahaemolyticus isolates. Comparison of data with those for the Rhode River area examined in the earlier studies of the annual cycle of V. parahaemolyticus suggests that the time of initiation of the annual cycle of V. parahaemolyticus in the open Bay proper may be influenced by various factors such as temperature and salinity, i.e., deeper water locations may show initiation of the V. parahaemolyticus annual cycle later than shallow areas. Confirmation of the presence of the organism in the samples studied was accomplished using numerical taxonomy with 19 reference strains also included in the analyses.
