  • Theiler, Arnold, Sir, 1867-1936; Transvaal Department of Agriculture (Pretoria : Government Printing and Stationery Office, 1908)
    Conclusions: (1) The inoculation of animals with horse foal blood of 1st, 2nd and 3rd generations caused a mortality of 7 out of 186, or 4 per cent. (2) The inoculation of animals with horse foal blood of 4th, 5th, 6th, ...

  • Theiler, Arnold, Sir, 1867-1936; Transvaal Department of Agriculture (Pretoria : Government Printing and Stationery Office, 1908)
    Conclusions: It would be seen from these notes that of four animals inoculated with English redwater, two failed to react or to show piroplasms, and in the other two instances a reaction ensued, accompanied with the ...
  • Theiler, Arnold, Sir, 1867-1936 (Pretoria: Government Printing and Stationery Office, 1908)
    Experiment 1 was the infection of animals known to be immune against redwater with piroplasma mutans. Experiment 2 was heifers infected with blue larval ticks in thew first instance, causing a pure infection of piroplasme ...

  • Theiler, Arnold, Sir, 1867-1936; Transvaal Department of Agriculture (Pretoria: Government Printing and Stationery Office, 1908)
    Conclusions: l. The simultaneous injection of serum 0 and adequate virus resulted in typical horse-sickness reactions, and the immunity obtained therefrom prevented a reaction when the adequate virus is subsequently ...
  • Theiler, Arnold, Sir, 1867-1936; Transvaal Department of Agriculture (Pretoria: Government Printing and Stationery Office, 1908)
    Conclusion:-The immunisation against a polyvalent virus with an adequate serum produces immunity which protects against any of its constituents. The immunity is strong enough to prevent a reaction in the majority of cases, ...

    The results of the experiments show very clearly the advantage that vaccinated sheep have over susceptible animals.
  • Theiler, Arnold, Sir, 1867-1936; Transvaal Department of Agriculture (Pretoria: Government Printing and Stationery Office, 1908)
    The full history of the treatment accorded to each animal is apparent from the tables. Conclusion : These experiments show conclusively that when a horse or mule is inoculated with a certain strain of virus, the animal, ...
  • Theiler, Arnold, Sir, 1867-1936; Transvaal Department of Agriculture (Pretoria: Government Printng and Stationery Office, 1908)
    Conclusions: Rhipicephalus decoloratus and amblyomma hebraeum must not be considered as hosts of piroplasma parvum. Rhipicephalus appendiculatus, evertsi, capensis, simus, and, according to Lounsbury, also nitens, must be ...

  • Theiler, Arnold, Sir, 1867-1936; Transvaal Department of Agriculture (Pretoria: Government Printer and Stationery Office, 1909)
    Conclusions: The injection of two-mule Tzaneen virus protected against four-mule Tzaneen virus, but not completely against the exposure virus. The two-mule Tzaneen virus, the four-mule Tzaneen virus, and the exposure virus ...

    Physical-chemical characteristics of horses such as body temperature, volume of erythrocytes, viscosity of blood, viscosity of serum, specific gravity of serum, conductivity of serum etc. were examined.
  • Viscosity 
    Frei, Walter; Transvaal Department of Agriculture (Pretoria: Government Printer and Stationery Office, 1909)
    Viscosity of blood, defibrinated blood, serum and plasma are compared.
  • Theiler, Arnold, Sir, 1867-1936; Transvaal Department of Agriculture (Pretoria: Government Printer and Stationery Office, 1909)
    Resume: The experiments prove that a virus may become inert in practice; this avirulency is due to some foreign matter, inasmuch as inert virus added to virulent sterile virus promptly produces avirulency. It is probable ...
  • Theiler, Arnold, Sir, 1867-1936; Transvaal Department of Agriculture (Pretoria: Government Printer and Stationery Office, 1909)
    Horses and mules were inoculated against piroplasmosis and it was found that Argentine and Transvaal horses and mules can safely be inoculated against piroplasmosis by using donkey foal blood of the fourth generation and upwards.
  • Theiler, Arnold, Sir, 1867-1936; Transvaal Department of Agriculture (Pretoria: Government Printer and Stationery Office, 1909)
    Conclusions: 1. Animals immunised with a polyvalent virus and tested with the same virus show reactions when subsequently retested with the identical virus. 2. When the immunity was tested with constituents of this ...
  • Frei, Walter; Transvaal Department of Agriculture (Pretoria: Government Printer and Stationery Office, 1909)
    Values for the volumes of blood corpuscles of horses, donkeys and sheep are examined.
