Abstract
An investigation was conducted to determine the processes involved in the contamination of shellfish by viruses. Results of binding-release studies show that the process involves the attachment of viruses to mucus secreted, and then ingested, by shellfish during feeding. Analysis of the mucus-virus bond involved selective degradation of the mucus and use of chemical agents to block carboxyl and sulfate groups on the mucus. Results obtained indicate that the attachment of virus to mucus is primarily ionic and involves the binding of viral particles to sulfate radicals on the mucopolysaccharide moiety of shellfish mucus.
摘要
开展了一项调查以确定贝类被病毒污染所涉及的过程。结合-释放研究结果表明，该过程涉及病毒附着于贝类摄食时分泌然后摄取的黏液。对黏液-病毒结合的分析涉及黏液的选择性降解以及使用化学试剂阻断黏液上的羧基和硫酸根。所得结果表明，病毒与黏液的附着主要是离子性的，涉及病毒颗粒与贝类黏液黏多糖部分上的硫酸根结合。
