  • 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; Parkes, E.B.H.; Transvaal Department of Agriculture (Pretoria: Government Printing and Stationery Office, 1908)
  • Theiler, Arnold, Sir, 1867-1936; Transvaal Department of Agriculture (Pretoria: Government Printing and Stationery Office, 1908)
  • 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, ...
  • Theiler, Arnold, Sir, 1867-1936; Orpen, J.M.; Transvaal Department of Agriculture (Pretoria: Government Printing and Stationery Office, 1908)
  • Theiler, Arnold, Sir, 1867-1936 (Pretoria : Government Printing and Stationery Office, 1908)
  • 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)
    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 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 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 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)
    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; Transvaal Department of Agriculture (Pretoria: Government Printer and Stationery Office, 1909)
    Conclusions: 1. The virus Tzaneen has in no instance been virulent for all mules injected; this virulency differs, so to say, from animal to animal; one particular animal seems to influence the virus in such a way that ...
  • Frei, Walter; Transvaal Department of Agriculture (Pretoria: Government Printer and Stationery Office, 1909)
    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.
  • 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 ...
  • 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.
  • Transvaal Department of Agriculture (Pretoria: Government Printer and Stationery Office, 1909)
    Resume: The surface tension IS a factor of enormous biological importance, especially for the phenomena of haemo- and bacteriolysis, phagocytosis and enzyme reactions. The surface tension of serum of horses suffering ...
  • Frei, Walter; Transvaal Department of Agriculture (Pretoria: Government Printer and Stationery Office, 1909)
    Experiments were undertaken to find differences by means of various physical methods combined between normal horses, horses suffering from horse-sickness, horses immune and hyperimmune against horse-sickness and serum ...
  • Theiler, Arnold, Sir, 1867-1936; Transvaal Department of Agriculture (Pretoria: Government Printer and Stationery Office, 1909)
    Resume: 1. A temperature of 0 C. retards the hatching of Rhipicephalus appendiculatus nymphae into adults. 2. A temperature of 0 C. does not interfere with the development of the parasite within the engorged nymphae. 3. ...
