  • The quantitative determination of the toxic factors produced by Clostridium botulinum (Van Ermengem, 1896) types C and D 
    Jansen, B.C.; South Africa. Dept. of Agricultural Technical Services; De Lange, M.; Reinecke, R.K.; Walker, Jane B.; De Kock, V.E.; Howell, P.G. (Pretoria : Government Printer, 1971)
    The Lf values of the C₁, C₂ and D factors produced by Clostridium botulinum types C and D were compared with the results of in vivo quantitative tests. It was found that the flocculation test is a reliable method of ...
  • The toxic antigenic factors produced by Clostridium botulinum types C and D 
    Jansen, B.C.; South Africa. Dept. of Agricultural Technical Services; De Lange, M.; Reinecke, R.K.; Walker, Jane B.; De Kock, V.E.; Howell, P.G. (Pretoria : Government Printer, 1971)
    The toxic factors produced by Clostridium botulinum (Van Ermengem, 1896), types C and D were determined. Monospecific antisera were prepared against the different factors. It was shown that type Cα produces factors C₁ ...
  • Tryptic activation of Clostridium botulinum type Cᵦ toxin 
    Jansen, B.C.; Knoetze, P.C.; South Africa. Dept. of Agricultural Technical Services; De Lange, M.; Reinecke, R.K.; Walker, Jane B.; De Kock, V.E.; Howell, P.G. (Pretoria : Government Printer, 1971)
    The toxicity of factor C₂ produced by C. botulinum type C ᵦ is increased by exposure to 0,1% trypsin at pH 7,5 for 30 minutes. If the tryptic action is allowed to continue at pH 7,5 at room temperature, destruction of ...
