    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)
    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 (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; 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 (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: 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 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 ...
  • Frei, Walter; Transvaal Department of Agriculture (Pretoria: Government Printer and Stationery Office, 1909)
    RESUME. 1. Piroplasmosis of the horse is a disease with periods also pronounced by physical-chemical alterations of blood and serum. 2. The haemolysis, produced by the intra-globular parasites, has to be considered to ...
  • Theiler, Arnold, Sir, 1867-1936; Transvaal Department of Agriculture (Pretoria: Government Printer and Stationery Office, 1909)
    CONCLUSIONS: 1. The exposure of animals immune against redwater in the low veld proved that this immunity protected against the redwater of that veld. 2. Animals immune against heartwater were protected against that ...
  • 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. ...
  • Frei, Walter; Transvaal Department of Agriculture (Pretoria: Government Printer and Stationery Office, 1909)
    Experiments were carried out to study quantitatively the influence of various organic colloids in different concentrations on the conductivity of the same electrolyte, that is to say, the influence of albumine, globuline, ...
