  • Immunization of mice against Corynebacterium pseudotuberculosis infection 
    Cameron, Colin McKenzie; Minnaar, J.L.; Weiss, K.E. (Pretoria : The Government Printer, 1969)
    Mice were immunized with vaccines containing whole dry bacteria and adjuvant. They were challenged by the intravenous injection of living bacteria. The degree of immunity obtained was best expressed in terms of the difference ...
  • Immunizing properties of Corynebacterium pseudotuberculosis cell walls 
    Cameron, Colin McKenzie; Minnaar, J.L.; Purdom, Mary R.; Weiss, K.E. (Published by the Government printer, Pretoria, 1969)
    Mice were successfully immunized with purified cell walls. The immunizing properties were not affected by extraction with ether: ethanol or trichloracetic acid but were destroyed after treatment with formamide.
  • Morphological variation in ephemeral fever virus strains 
    Lecatsas, G.; Theodoridis, A.; Els, H.J.; Weiss, K.E. (Pretoria : The Government Printer, 1969)
  • The morphology of the immature stages of some South African Culicoides species (Diptera : Ceratopogonidae) 
    Nevill, E.M.; Weiss, K.E. (Published by the Government Printer, Pretoria, 1969)
    The morphology of the fourth larval stage of eight South African Culicoides species and of the pupae of seven species was studied. The value of existing taxonomic characters was tested and several useful new characters ...
  • Observations on bilharziasis of domestic ruminants in South Africa 
    McCully, R.M.; Kruger, S.P.; Jansen, B.C. (Published by the Government Printer, Pretoria, 1969)
    Bilharziasis of 100 sheep and 14 cattle caused by Schistosoma mattheei Veglia & Le Roux, 1929, was studied in detail from the histopathological aspect. The ovine cases included natural as well as experimentally infested ...
  • On the relationship between bluetongue, African horsesickness and reoviruses : hybridization studies 
    Huismans, H. (Henk), 1942-; Verwoerd, Daniel Wynand; Weiss, K.E. (Published by the Government Printer, Pretoria, 1969)
    The double-stranded ribonucleic acid from bluetongue virus (BTV), African horsesickness virus (AHSV) and reovirus has been tested for hybridization with messenger RNA derived from BTV and reovirus-infected cells. No ...
  • The optimal conditions for the multiplication of Neethling-type lumpy skin disease virus in embryonated eggs 
    Van Rooyen, P.J.; Munz, E.K.; Weiss, K.E.; Weiss, K.E. (Published by the Government Printer, Pretoria, 1969)
    Maximum yields of lumpy skin disease virus were obtained in the chorio-allantoic membranes of 5- to 7-day embryonated eggs incubated at 33.5° to 35°C for 5 to 6 days. The route of inoculation did not significantly affect ...
  • A statistical method for comparing worm burdens in two groups of sheep 
    Groeneveld, Hendrik T.; Reinecke, R.K.; Weiss, K.E. (Published by the Government Printer, Pretoria, 1969)
    In groups of experimentally infested sheep, worm distributions are markedly skew. In controlled anthelmintic tests, the worm burdens of treated and control sheep have different distributions and this invalidates the use ...
  • Strongylidoses : delafondiasis in the zebra 
    McCully, R.M.; Kruger, S.P.; Basson, P.A.; Ebedes, H.; Van Niekerk, J.W.; Jansen, B.C. (Published by the Government Printer, Pretoria, 1969)
    Post mortem examinations on 125 zebras [Equus burchelli (Gray, 1824)] from the Kruger and Etosha National Parks revealed nodular and cystlike lesions of parasitic thrombophlebitis within the intrahepatic branches of the ...
  • Studies on specific oculo-vascular myiasis (uitpeuloog) in sheep. V. Histopathology 
    Basson, P.A.; Weiss, K.E. (Published by the Government printer, Pretoria, 1969)
    Specimens from 51 sheep and one goat were studied microscopically. Myiasis by Gedoelstia larvae occurred mainly in the organs of the head, neck and thorax, the eyes, brain, heart and blood vessels being most frequently ...
  • Subject index 
    Weiss, K.E.; Jansen, B.C. (Pretoria : The Government Printer, 1969)
  • A taxonomic revision of the genus Taenia Linnaeus, 1758 s. str 
    Verster, Anna; Jansen, B.C. (Published by the Government Printer, Pretoria, 1969)
    The genus Taenia Linnaeus, 1758 sensu strictu is revised. Besides the type species, Taenia solium Linnaeus, 1758, the valid species are: T. acinonyxi; T. brachyacantha; T. crassiceps; T. crocutae; T. endothoracicus; T. ...
