Monkeypox virus as a source of whitepox viruses
Abstract:
Monkeypox virus cloning and isolation of the so-called 'white' clones from white pocks which this virus forms on the chorioallantoic membrane (CAM) were carried out. The isolated clones were stable and differed considerably from the parental strain. By their properties, they were identical to whitepox viruses formerly isolated from wildlife monkeys and rodents in Equatorial Africa. Besides stable 'white' clones, a number of virus cultures in the process of cloning were obtained which differed in quantitative content of virions, forming on CAM white pocks and pocks with hemorrhages. It appeared that the properties of the viral population as a whole (reaction type on rabbit skin, hemagglutination activity, etc.) depended on the rate of virions produced with different characteristics.
