Wallace P. Rowe lecture. Poxviruses of laboratory animals.

Currently the subfamily Chordopoxvirinae, the poxviruses of vertebrates, is subdivided into eight genera, containing some 20-30 species; an inexact figure because the birdpox viruses have not yet been properly investigated taxonomically. I have discussed seven species belonging to three genera, all of which have caused infection and usually disease in mammals commonly used in the laboratory. The list could have been extended had I included chickens and swine as laboratory animals, for that would have meant that I would have spoken about the birdpox viruses and swinepox virus as well. However, I think I have said enough to remind you of the importance of this family of viruses to those of you concerned with laboratory animal medicine. I believe that Wally Rowe would have been interested, for every case I have described presents problems in the ecology of viruses, and like my mentor Macfarlane Burnet, Wally approached virology from an ecological point of view, whether he was thinking about the DNA provirus of retroviruses and the host chromosome, the pathogenesis of disease, or the spread of viruses in animal populations, all topics to which he made major contributions.
