The seasonal incidence and occurrence of indicator organisms and pathogens were studied at four sites in the Rhode River, a subestuary of Chesapeake Bay. The highest frequency of occurrence of total and fecal coliforms and fecal streptococci was in Muddy Creek, a marsh area receiving pasture land runoff. Second highest frequency of occurrence of these bacteria was in Cadle Creek, a populated area. Lowest measurements of these parameters were obtained at stations in the central portion of the Rhode River. No Salmonella spp. were detected by the methods employed in this study. However, it is concluded that if these organisms are present, the concentrations are less than or equal to 1 organism per liter. The presence of Clostridium botulinum was detected in 12% of the samples tested.
在切萨皮克湾的一个子河口罗德河的四个地点,对指示生物和病原体的季节性发病率及出现情况进行了研究。总大肠菌群、粪大肠菌群和粪链球菌出现频率最高的是泥泞溪,这是一个接收牧场径流的沼泽地区。这些细菌出现频率第二高的是卡德尔溪,一个人口密集地区。这些参数的最低测量值是在罗德河中部的站点获得的。通过本研究采用的方法未检测到沙门氏菌属。然而,可以得出结论,如果存在这些生物,其浓度小于或等于每升1个生物体。在所检测的样本中,12%检测到了肉毒梭菌的存在。
