The prevalence of human enteric viruses in bivalve molluscan shellfish and shrimp collected off the south west coast of India was studied to assess the extent of fecal pollution of coastal environment. Out of 194 samples analyzed, 37% of oyster, 46% of clam and 15% of shrimp samples were positive for enteroviruses (EV). Adenoviruses (ADV) were detected in 17% of oyster and 27% of clam samples. However, other enteric viruses such as noroviruses (NoV) and hepatitis A virus (HAV) were not detected in any of the samples. High prevalence of EV and ADV was noticed between May to December. Thirty four percent of oyster and 49% of clam samples showed fecal coliform values higher than the limit. MS-2 phage was detected in 57% of oyster and 73% of clam samples. The presence of MS-2 phage and human enteric viruses showed association while fecal coliforms and enteric viruses showed no association. However, 17 samples, which were positive for enteric viruses (EV and ADV), were negative for MS-2 phage.
为评估印度西南沿海环境的粪便污染程度，对从该海域采集的双壳贝类软体动物和虾类中的人类肠道病毒流行情况进行了研究。在分析的194个样本中，37%的牡蛎样本、46%的蛤类样本和15%的虾类样本肠道病毒（EV）呈阳性。17%的牡蛎样本和27%的蛤类样本检测到腺病毒（ADV）。然而，在任何样本中均未检测到其他肠道病毒，如诺如病毒（NoV）和甲型肝炎病毒（HAV）。5月至12月期间，EV和ADV的流行率较高。34%的牡蛎样本和49%的蛤类样本粪便大肠菌群值高于限值。57%的牡蛎样本和73%的蛤类样本检测到MS-2噬菌体。MS-2噬菌体与人类肠道病毒的存在呈关联，而粪便大肠菌群与肠道病毒无关联。然而，17个肠道病毒（EV和ADV）呈阳性的样本，MS-2噬菌体检测为阴性。
