水体沉积物中病毒属于环境病毒学的范畴,这类病毒污染作为传播病毒性疾病的一个重要因素,有其广泛内容和实际意义。 一、淤泥中病毒污染情况 至今已发现120余种(型)病毒可以从受感染的人体排出污染水体,从而随水中一些固体物质沉积到水底。这些病毒主要是肠道病毒(表1)。 此外,在人类排泄物中还发现有巨细胞 Viruses in sediments of water belong to the category of environmental virology. Such virus contamination has an extensive and practical significance as an important factor in the spread of viral diseases. First, the virus contamination in the silt has so far been found that more than 120 kinds of (type) virus can be discharged from the infected human body polluted water, which deposited with the water with some solid material to the bottom. These viruses are predominantly enterovirus (Table 1). In addition, giant cells are found in human waste
