The DNAs of eight parapoxviruses (four stomatitis papulosa viruses isolated from infected calves, a pseudocowpox virus isolated from a teat lesion of an infected cow and three orf viruses, one isolated from an infected sheep and two isolated from human infections) were analysed in CsCl gradients. The mole % of G+C was calculated from the buoyant density and found to be approx. 63% for all virus isolates examined. Parapoxvirus DNA thus has by far the highest G+C content of all poxvirus DNAs so far examined.
