  • Aetiology of jaagsiekte : experimental transmission to lambs by means of cultured cells and cell homogenates 
    Verwoerd, Daniel Wynand; De Villiers, Ethel-Michele; Tustin, R.C.; Steyn, P.J.J.; Bigalke, R.D.; Cameron, Colin McKenzie; Gilchrist, Frances M.C.; Morren, A.J.; Verster, Anna J.M. (Published by the Government Printer, Pretoria., 1980)
    Studies on the transmission of jaagsiekte (ovine pulmonary adenomatosis) both by sub inoculation of cells of known sex and by cell homogenates into male and female lambs are reported. The results obtained indicate a ...
  • Aetiology of Jaagsiekte : transmission by means of subcellular fractions and evidence for the involvement of a retrovirus 
    Verwoerd, Daniel Wynand; De Villiers, Ethel-Michele; Tustin, R.C.; Steyn, P.J.J.; Bigalke, R.D.; Cameron, Colin McKenzie; Gilchrist, Frances M.C.; Morren, A.J.; Verster, Anna J.M.; Verwoerd, Daniel Wynand; Walker, Jane B. (Pretoria : The Government Printer, 1980)
    Jaagsiekte (ovine pulmonary adenomatosis) was transmitted to new-born lambs by inoculation of the microsomal fraction of a cytoplasmic extract of cultured tumour cells or tumour tissue. Various treatments of the biologically ...
  • Presence of Herpesvirus ovis DNA sequences in cellular DNA from sheep lungs affected with jaagsiekte (pulmonary adenomatosis) 
    De Villiers, Ethel-Michele; Verwoerd, Daniel Wynand; Steyn, P.J.J.; Bigalke, R.D.; Cameron, Colin McKenzie; Gilchrist, Frances M.C.; Morren, A.J.; Verster, Anna J.M.; Verwoerd, Daniel Wynand; Walker, Jane B. (Published by the Government Printer, Pretoria., 1980)
    To investigate further the possible involvement of Herpesvirus avis in the aetiology of jaagsiekte, the kinetics of re-association of viral DNA and DNA isolated from tumour tissue as well as from cell cultures derived from ...
  • The serological relationship of herpesvirus ovis to other herpesviruses and its possible involvement in the aetiology of jaagsiekte 
    Verwoerd, Daniel Wynand; Meyer-Scharrer, Elizabeth; De Villiers, Ethel-Michele; Broekman, J.; Steyn, P.J.J.; Bigalke, R.D.; Morren, A.J.; Verster, Anna J.M.; Verwoerd, Daniel Wynand; Walker, Jane B.; Cameron, Colin McKenzie; Gilchrist, Frances M.C. (Published by The Government Printer, Pretoria, 1979)
    Cross-neutralization studies showed that 3 different isolates of herpesvirus ovis from cell cultures derived from the lungs of sheep suffering from jaagsiekte were not only identical but were also related to a similar ...
