  • Further notes on Piroplasma mutans : a new species of Piroplasma in South African cattle 
    Theiler, Arnold, Sir, 1867-1936 (Pretoria: Government Printing and Stationery Office, 1908)

  • Further notes on species of Trichodectidae with descriptions of new species 
    Bedford, G.A.H.; Du Toit, P.J. (Pretoria : Government Printer, 1939)
    Werneck (Mem. do lnstit. Oswaldo Cruz, XXXI, iii, pp. 496-589, 1936) recently reduced the family Trichodectidae to a single genus, but such a procedure is unwarrantable. If one examines casually the figures of species in ...
  • Further observations on an intratubercular sensory receptor of Schistosoma mattheei 
    Kruger, F.J.; Tiedt, L.; Du Preez, L.; Hamilton-Attwell, V.L.; Bigalke, R.D. (Published by the Government Printer, Pretoria., 1986)
    A structure, presumably a sensory receptor in the nippled tubercles of Schistosoma mattheei, previously observed by scanning electron microscopy, was studied further by light and transmission electron miccroscopy. The ...
  • Further observations on the cystine deficiency of lucerne proteins and the effect of heat and incubation upon their growth-promoting value 
    Kellermann, J.H.; Du Toit, P.J. (Pretoria : Government Printer, 1935)
    Lucerne is not only high in minerals and vitamins but also in proteins, yet, curiously enough, it is rather low in cysteine as determined biologically with rats by Haag (1931). This discovery may be of importance to parts ...
  • Further observations on the electrophoretic characterization of South African Schistosoma mattheei and S. haematobium 
    Kruger, F.J.; Bigalke, R.D. (Published by the Government Printer, Pretoria., 1988)
    Eleven enzymes, which were used to compare South African S. mattheei and S. haematobium in a former study, were employed to study intraspecific variation within S. mattheei, using starch gel electrophoresis and iso-electric ...
  • Further observations on the pathology of bluetongue in sheep 
    Thomas, A.D.; Neitz, W.O.; Du Toit, P.J. (Pretoria : The Government Printer, 1947)
    From the findings reviewed in this paper it seems clear that the pathological changes in bluetongue concern mainly: (a) the vascular system, (b) the skeletal musculature.
  • Further observations on the scrotal skin temperature of the bull, with some remarks on the intra-testicular temperature 
    Riemerschmid, G.; Quinlan, John; Du Toit, P.J. (Pretoria : The Government Printer, 1941)
    1. The temperature of the scrotal surface has been recorded at various air-temperatures within the range 10°C. to 40°C. (50°F. to 104°F.). 2. At low air-temperatures (10°C. to 25°C.) the temperature on areas I, II, and ...
  • Further observations on the ultrastructure of ephemeral fever virus 
    Lecatsas, G.; South Africa. Dept. of Agricultural Technical Services; Tustin, R.C.; De Lange, M.; Reinecke, R.K.; Walker, Jane B.; De Kock, V.E. (Pretoria : Government Printer, 1970)
    Electron microscope observations on ephemeral fever virus showed that the electron-dense material was helical in structure, that probably two strands 4 nm in diameter formed a limb approx. 17 nm in diameter with one complete ...
  • Further physiopathological features of experimental Homeria glauca (Wood and Evans) N.E.Br. poisoning in Merino sheep 
    Button, C.; Mulders, M.S.G.; Bigalke, R.D. (Published by The Government Printer, Pretoria, 1984)
    Three Merino sheep were given 3 g/kg of dried, finely-milled Homeria glauca (Natal yellow tulp) plant material intraruminally. Plasma glucose, cortisol, catecholarnines and lactate were measured hourly and also at the ...
