Direct plaque formation with representative strains of hog cholera virus (HCV) has been obtained using several pig kidney cell lines under agar overlay. HCV-infected cells appear as hazy plaques when viewed against an indirect light source, and as white plaques after neutral red staining. HCV assay by direct plaque procedure is rapid and convenient and gives infectivity titres identical to the fluorescent focus assay technique.
在琼脂覆盖下,使用几种猪肾细胞系已成功实现了猪霍乱病毒(HCV)代表性毒株的直接蚀斑形成。当在间接光源下观察时,感染HCV的细胞呈现为模糊的蚀斑,而经中性红染色后则呈现为白色蚀斑。通过直接蚀斑法进行的HCV检测快速便捷,且所得到的感染性滴度与荧光灶检测技术相同。
