  • The 3A non-structural-protein coding region of the southern African SAT type isolates differs from that of other foot-and-mouth disease viruses 
    Vosloo, Wilna; Nel, Louis Hendrik; Heath, Livio Edward; Van Rensburg, H.G. (Hester Gertruida); Boomker, Jacob Diederik Frederik (Published jointly by the Agricultural Research Council, ARC-Onderstepoort Veterinary Institute and the Faculty of Veterinary Science, University of Pretoria., 2001)
    The 3A non-structural protein of foot-and-mouth disease viruses is a relatively conserved protein comprising 153 amino acids. Recent studies have demonstrated correlation between mutations in the 3A non-structural-protein-coding ...
  • Development of a diagnostic one-tube RT-PCR for the detection of Rift Valley fever virus 
    Nel, Louis Hendrik; Espach, Anel; Romito, M.; Viljoen, G.J.; Boomker, Jacob Diederik Frederik (Published jointly by the Agricultural Research Council, ARC-Onderstepoort Veterinary Institute and the Faculty of Veterinary Science, University of Pretoria., 2002)
    Diagnosis of Rift Valley fever (RVF) is based on serology and virus isolation. The disadvantages of the former include poor sensitivity, high cost, risks associated with using infectious virus as antigen, the lengthy ...
  • Molecular epidemiology of rabies virus in South Africa 
    Nel, Louis Hendrik; Thomson, G.R. (Gavin); Von Teichman, B.F.; Rabies in Southern and Eastern Africa. Workshop. (1993, Pretoria, South Africa); Verwoerd, Daniel Wynand (Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1993)
    Nucleic acid sequence analysis was used to determine the phylogenetic relationships amongst rabies viruses isolated from typical canid hosts such as bat-eared fox, jackal and dog in South Africa (SA). Geographical factors ...
  • A nucleotide-specific polymerase chain reaction assay to differentiate rabies virus biotypes in South Africa 
    Nel, Louis Hendrik; Bingham, J.; Jacobs, Jeanette Antonio; Jaftha, Julian Bernard; Verwoerd, Daniel Wynand (Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1998)
    Antigenic and nucleotide sequence analyses have shown that two distinct biotypes of rabies virus are circulating in South Africa. One of these typically infects members of the family Canidae, while the other comprises a ...
  • PCR-based detection of the transovarial transmission of Uruguayan Babesia bovis and Babesia bigemina vaccine strains 
    Nel, Louis Hendrik; Gayo, V.; Romito, M.; Solari, M.A.; Viljoen, Gerrit Johannes; Boomker, Jacob Diederik Frederik (Published jointly by the Agricultural Research Council, ARC-Onderstepoort Veterinary Institute and the Faculty of Veterinary Science, University of Pretoria., 2003)
    Bovine babesiosis is responsible for serious economic losses in Uruguay. Haemovaccines play an important role in disease prevention, but concern has been raised about their use. It is feared that the attenuated Babesia ...
