  • Tetraphyllin B and epi-tetraphyllin B from Adenia glauca Schinz 
    Spencer, K.C.; Seigler, D.S.; Steyn, P.J.J.; Bigalke, R.D.; Cameron, Colin McKenzie; Gilchrist, Frances M.C.; Jordaan, E.; Morren, A.J.; Verster, Anna J.M.; Verwoerd, Daniel Wynand; Walker, Jane B. (Published by The Government Printer, Pretoria, 1982)
    Tetraphyllin B and epi-tetraphyllin B have been isolated from the South African plant Adenia glauca Schinz in an approximate ratio of 5 : 1. The structures were established by ¹H-NMR.
  • The value of the microtitre serum agglutination test as a second screening test in bovine brucellosis 
    Herr, S.; Te Brugge, Lesley A.; Guiney, M.C.M.; Steyn, P.J.J.; Bigalke, R.D.; Cameron, Colin McKenzie; Gilchrist, Frances M.C.; Jordaan, E.; Morren, A.J.; Verster, Anna J.M.; Verwoerd, Daniel Wynand; Walker, Jane B. (Published by The Government Printer, Pretoria, 1982)
    The use of the serum agglutination test (SAT) as a 2nd screening test led to a reduction in false negative screening reactions especially in sera delayed in transit and provided an easy check on human error in the ...
  • Virulence and heterologous strain immunity of South African and Australian Babesia bovis strains with reduced pathogenicity 
    De Vos, A.J.; Bessenger, R.; Fourie, C.G.; Steyn, P.J.J.; Bigalke, R.D.; Cameron, Colin McKenzie; Gilchrist, Frances M.C.; Jordaan, E.; Morren, A.J.; Verster, Anna J.M.; Verwoerd, Daniel Wynand; Walker, Jane B. (Published by The Government Printer, Pretoria, 1982)
    A South African Babesia bovis strain showed loss of virulence after 10 rapid passages in splenectomized calves. The virulence was comparable with that of an attenuated Australian vaccine strain. Vaccination of crossbred ...
