Abstract
Summary
Groups of newborn hamsters were inoculated with one of each of 33 picor-naviruses, 7 paramyxoviruses, 3 reoviruses, and 1 herpesvirus, of human origin, obtained from the American Type Culture Collection. Low tumor incidences were observed following inoculation of echovirus types 12, 17, 22, 23, and 29, respiratory syncytial virus, and reovirus type 3. Tumors observed in inoculated animals are compared with spontaneous tumors. The possibility of etiologic involvement of contaminating oncogenic viruses, or of enhancement or activation of enzootic latent tumor agents by non-oncogenic virus inoculation is discussed.
The authors are grateful to Jack G. Burke for technical assistance and to Dr. H. J. Spjut for consultation on the histopathology.
