This technique has also been used extensively in studies on the structure of pox viruses. Horne & Wildy (1963) have reviewed the results obtained by various investigators working with this group of viruses. The more recently published findings of Buttner, Giese, Muller & Peters (1964) and Peters, Muller & Buttner (1964) suggest that the viruses of the pox group can be divided into the following...

A restriction fragment length polymorphism (RFLP) assay was developed to identify and differentiate Old World, African-Eurasian orthopoxviruses (OPV): variola, vaccinia, cowpox, monkeypox, camelpox, ectromelia, and taterapox viruses. The test uses amplicons produced from virus genome DNA by PCR with a consensus primer pair designed from sequences determined for the cytokine response modifier B ...

We have sequenced DNA equivalent to the E5R ORF of Copenhagen vaccinia virus from an additional strain of vaccinia and from cowpox (three strains), camelpox (two strains), taterapox and ectromelia viruses. None of these showed the disruptions previously reported in the equivalent region of monkeypox virus. We also constructed a viable recombinant of vaccinia virus strain Dairen in which the E5R...

Variola virus, the causative agent of smallpox, is a potential bioweapon. The development of new antiviral compounds for smallpox prophylaxis and treatment is critical, especially because the virus can acquire resistance to the drugs that are currently available. We have identified novel small chemical inhibitors that target DNA synthesis of vaccinia, the prototypical poxvirus. Robotic high-thr...

In the course of evolution, viruses have developed various molecular mechanisms to evade the defense reactions of the host organism. When understanding the mechanisms used by viruses to overcome manifold defense systems of the animal organism, represented by molecular factors and cells of the immune system, we would not only comprehend better but also discover new patterns of organization and f...
