Under defined plaquing conditions, three attenuated strains of rubella virus showed different plaque morphology and plaque size when tested in Vero cell cultures. The Cendehill strain of rubella virus formed distinct, ring-shaped plaques, while strains HPV77 and RA27/3 produced clear plaques that could be distinguished by their different size. These distinguishing characteristics remained preserved even after the vaccine strains were passaged five consecutive times in Vero cell cultures.
在规定的蚀斑形成条件下，三种风疹病毒减毒株在Vero细胞培养物中进行测试时，表现出不同的蚀斑形态和蚀斑大小。风疹病毒的Cendehill株形成明显的环形蚀斑，而HPV77株和RA27/3株产生的清晰蚀斑可通过其不同大小加以区分。即使这些疫苗株在Vero细胞培养物中连续传代五次后，这些显著特征仍然得以保留。
