  • Krimpsiekte in a sheep following a single dose of Tylecodon ventricosus (Burm. f.) Toelken and the isolation of tyledoside D from this plant species 
    Vleggaar, Robert; Botha, C.J. (Christoffel Jacobus); Kellerman, T. Stephanus; Schultz, R.A. (Rowena Anitra); Erasmus, G.L.; Retief, E.P.; Verwoerd, Daniel Wynand (Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1998)
    Tylecodon ventricosus induced severe respiratory distress in two penned sheep without any electrocardiographic abnormalities being recorded. Based on the results it appears as if T. ventricosus predominantly induces the ...
  • Protein aggregation complicates the development of baculovirus-expressed African horsesickness virus serotype 5 VP2 subunit vaccines 
    Du Plessis, M.; Cloete, M.; Aitchison, Henry; Van Dijk, A.A.; Verwoerd, Daniel Wynand (Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1998)
    This paper describes the expression of a cloned African horsesickness virus (AHSV) serotype 5 VP2- gene by a baculovirus recombinant that was generated by the BAC-TO-BAC™ system. Immunization of horses with crude cell ...
  • Detection and characterization of foot-and-mouth disease virus in sub-Saharan Africa 
    Bastos, Armanda D.S.; Verwoerd, Daniel Wynand (Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1998)
    Genomic amplification of the VP1 gene of SAT-type foot-and-mouth disease virus (FMDV) was performed with published and novel oligonucleotide primers. The primer pair with the highest SAT-type recognition (67 %) was identified ...
  • Antigenic and genetic analysis of canine parvoviruses in southern Africa
