  • Immunization of mice and calves against Salmonella dublin with attenuated live and inactivated vaccines 
    Cameron, Colin McKenzie; Fuls, W.J.P.; De Kock, V.E.; Bigalke, R.D.; Cameron, Colin McKenzie; Gilchrist, Frances M.C.; Morren, A.J.; Verster, Anna J.M.; Verwoerd, Daniel Wynand; Walker, Jane B. (Published by The Government Printer, Pretoria, 1976)
    Previous findings, viz. that mice can be successfully immunized against infection with Salmonella dublin with either live or inactivated vaccine, were confirmed. Immunity lasted for at least 12 weeks in mice which had been ...
  • Cerebral babesiosis in a new-born calf 
    Imes, G.D.; Cullen, J.S.C.; De Vos, A.J.; De Kock, V.E.; Bigalke, R.D.; Cameron, Colin McKenzie; Gilchrist, Frances M.C.; Morren, A.J.; Verster, Anna J.M.; Verwoerd, Daniel Wynand; Walker, Jane B. (Published by The Government Printer, Pretoria, 1976)
    A case of intra-uterine transmission of Babesia bovis is reported. The calf was born normally but showed signs of intravascular haemolyse is and nervous involvement 24 h after birth. It died shortly afterwards from cerebral ...
  • Maldronksiekte in cattle : a neuronopathy caused by Solanum kwebense N.E. Br. 
    Pienaar, J.G.; Kellerman, T.S.; Basson, P.A.; Jenkins, W.L.; Vahrmeijer, J.; De Kock, V.E.; Bigalke, R.D.; Cameron, Colin McKenzie; Gilchrist, Frances M.C.; Morren, A.J.; Verster, Anna J.M.; Verwoerd, Daniel Wynand; Walker, Jane B. (Published by The Government Printer, Pretoria, 1976)
    A neurological disease of cattle (maldronksiekte), occurring in a localized area of the Northern Transvaal, was experimentally reproduced by feeding Solanum kwebense plants to cattle. The disease is characterized by temporary ...
  • Kinetics of the IgM and IgG immunological response to sheep erythrocytes and bluetongue virus in mice 
    Oellermann, R.A.; Carter, P.; Marx, M.J.; De Kock, V.E.; Bigalke, R.D.; Cameron, Colin McKenzie; Gilchrist, Frances M.C.; Morren, A.J.; Verster, Anna J.M.; Verwoerd, Daniel Wynand; Walker, Jane B. (Published by The Government Printer, Pretoria, 1976)
    The IgM and IgG response of mice to sheep erythrocytes (SRBC) and bluetongue virus (BTV) was determined by means of haemolytic plaque assays. Maximum primary IgM response to SRBC occurred after 4 days but declined rapidly ...
  • The fine structure of merozoites of Babesia bovis in the gut epithelium of Boophilus microplus 
    Potgieter, F.T.; Els, H.J.; Van Vuuren, A.S.; De Kock, V.E.; Bigalke, R.D.; Cameron, Colin McKenzie; Gilchrist, Frances M.C.; Morren, A.J.; Verster, Anna J.M.; Verwoerd, Daniel Wynand; Walker, Jane B. (Pretoria : The Government Printer, 1976)
    Electron microscopic studies on merozoites of Babesia bovis in epithelial cells of the gut of Boophilus microplus revealed that the pellicle apparently consists of 3 membranes, and an osmiophilic layer intimately associated ...
  • Volatile fatty acid metabolism in sheep. 1. Average daily volatile fatty acid production in the rumen of sheep fed lucerne hay 
    Van der Walt, J.G.; Briel, B. J.; De Kock, V.E.; Bigalke, R.D.; Cameron, Colin McKenzie; Gilchrist, Frances M.C.; Morren, A.J.; Verster, Anna J.M.; Verwoerd, Daniel Wynand; Walker, Jane B. (Published by The Government Printer, Pretoria, 1976)
    Changes in the total concentration of the volatile fatty acid (VFA) pool in the rumen were followed over a 24 hour period in 2 groups of sheep, 1 fed at 08h00 and the other twice daily at 08h00 and 20h00. Although similar ...
  • Bluetongue virus as a cause of hydranencephaly in cattle 
    Barnard, B.J.H.; Pienaar, J.G.; De Kock, V.E.; Bigalke, R.D.; Cameron, Colin McKenzie; Gilchrist, Frances M.C.; Morren, A.J.; Verster, Anna J.M.; Verwoerd, Daniel Wynand; Walker, Jane B. (Published by The Government Printer, Pretoria, 1976)
    Hydranencephaly was produced in a foetus and a calf by intra-uterine infection with an attenuated Type 10 bluetongue virus. Laparotomy was performed on the respective dams and the foetust:s, respectively 126 days and 138 ...
  • A study on the pathogenesis of bluetongue : replication of the virus in the organs of infected sheep 
    Pini, A.; De Kock, V.E.; Bigalke, R.D.; Cameron, Colin McKenzie; Gilchrist, Frances M.C.; Morren, A.J.; Verster, Anna J.M.; Verwoerd, Daniel Wynand; Walker, Jane B. (Published by The Government Printer, Pretoria, 1976)
    The pathogenesis of bluetongue infection was studied by the titration of the virus in tissue samples taken from sheep inoculated subcutaneously in the auricula of the ear with 76 TC ID₅₀ the plaque-purified type 10 bluetongue ...
  • Experimental intraspinal Trypanosoma equiperdum infection in a horse 
    Barrowman, P.R.; De Kock, V.E.; Bigalke, R.D.; Cameron, Colin McKenzie; Gilchrist, Frances M.C.; Morren, A.J.; Verster, Anna J.M.; Verwoerd, Daniel Wynand; Walker, Jane B. (Published by The Government Printer, Pretoria, 1976)
