The numbers of fecal coliforms and enteroviruses present in oysters and/or their growing waters of two Mississippi reefs were determined over a 12-month period. Bacterial and viral levels reflected the classification of the waters at each location as set by the Mississippi State Board of Health in compliance with the National Shellfish Sanitation Program, but statistically significant correlations between these levels were not observed. Twelve viral isolates were found at an approved oyster harvesting location, eight of which were identified as poliovirus type 1. At the prohibited site, 146 viruses were isolated including poliovirus types 1 and 2, echovirus type 24 and several isolates which remain to be identified. The number of virus isolates from samples from each location represented approximately 35% of the number of plaques observed; however, no consistent ratio of plaque to confirmed virus was demonstrated. The results suggest that the fecal coliform levels in oyster growing waters do not reflect the level of virus contaminaton in either approved or prohibited waters.
在12个月的时间里，对密西西比州两个牡蛎礁的牡蛎及其生长水域中的粪大肠菌群和肠道病毒数量进行了测定。细菌和病毒水平反映了密西西比州卫生委员会根据国家贝类卫生计划对每个地点水域的分类，但未观察到这些水平之间具有统计学意义的相关性。在一个经批准的牡蛎捕捞地点发现了12株病毒分离株，其中8株被鉴定为1型脊髓灰质炎病毒。在禁止捕捞的地点，分离出146种病毒，包括1型和2型脊髓灰质炎病毒、24型艾柯病毒以及几种有待鉴定的分离株。每个地点样本中的病毒分离株数量约占观察到的噬菌斑数量的35%；然而，未证明噬菌斑与确诊病毒之间存在一致的比例。结果表明，牡蛎生长水域中的粪大肠菌群水平不能反映经批准或禁止水域中的病毒污染水平。
