  • Sedimentation of bacteria with polyethylene glycol 
    Cameron, Colin McKenzie; Weiss, K.E.; De Kock, V.E.; Bigalke, R.D.; Cameron, Colin McKenzie; Verster, Anna J.M.; Walker, Jane B. (Pretoria : The Government Printer, 1974)
    Experiments are reported which show that the addition of 4,0% polyethylene glycol (6 000 MW) to liquid cultures of Clostridium welchii Type D , Pasteurella and Vibrio fetus (venerialis) will effectively sediment the bacteria. ...
  • Serum protein fractions as determined by cellulose acetate electrophoresis in Schistosoma mattheei infested sheep 
    Van Zyl, L.C.; De Kock, V.E.; Bigalke, R.D.; Cameron, Colin McKenzie; Verster, Anna J.M.; Walker, Jane B. (Pretoria : The Government Printer, 1974)
    The serum protein fraction values of Dorper sheep infested with Schistosoma mattheei were determined by cellulose acetate electrophoresis at regular intervals for 15 months. Statistical analyses showed that increases in ƴ ...
  • Stimulation of the immune response in vivo by different nucleic acids 
    Oellermann, R.A.; De Kock, V.E.; Bigalke, R.D.; Cameron, Colin McKenzie; Verster, Anna J.M.; Walker, Jane B. (Pretoria : The Government Printer, 1974)
    The number of haemolytic plaque forming cells (PFCs) in the spleens of normal mice could not be increased by the injection of nucleic acids. However, when nucleic acids were injected into mice simultaneously with a priming ...
  • Studies on Haemonchus contortus. I. The influence of previous exposure to Trichostrongylus axei on infestation with H. contortus 
    Reinecke, R.K.; De Kock, V.E.; Bigalke, R.D.; Cameron, Colin McKenzie; Verster, Anna J.M.; Walker, Jane B. (Pretoria : The Government Printer, 1974)
    A group of Merino sheep, aged 6-7 months was infested orally with 50 000 infective larvae of Trichostrongylus axei. This group and a control group were challenged 90-92 days later with 50 000 infective larvae of Haemonchus ...
  • Studies on schistosomiasis. 6. A field outbreak of bilharzia in cattle 
    Van Wyk, Jan Aucamp; Bartsch, R.C.; Van Rensburg, L.J.; Heitmann, L.P.; Goosen, P.J.; De Kock, V.E.; Bigalke, R.D.; Cameron, Colin McKenzie; Verster, Anna J.M.; Walker, Jane B. (Pretoria : The Government Printer, 1974)
    An outbreak of bilharzia (Schistosoma mattheei) infestation involving about 100 oxen on the farm Otthilie near Tolwe in northern Transvaal is described. Infestation of the cattle appears to have occurred per os from a ...
  • Studies on the effect of cortisol on the primary immune response to sheep erythrocytes in vivo by mouse spleen cells 
    Waldek, J.F.; Hellig, H.R.; De Kock, V.E.; Bigalke, R.D.; Cameron, Colin McKenzie; Verster, Anna J.M.; Walker, Jane B. (Pretoria : The Government Printer, 1974)
    Female mice were injected with a suspension of 0, 2 ml of 10 per cent v/v sheep red blood cells (SRBC) and sacrificed on the 5th day for recording of spleen mass and assay of plaque-forming cells (PFCs) in the spleens. ...

  • A survey of diseases among 100 free-ranging baboons (Papio ursinus) from the Kruger National Park 
    McConnell, E.E.; Basson, P.A.; De Vos, Valerius; Myers, Betty J.; Kuntz, R.E.; De Kock, V.E.; Bigalke, R.D.; Cameron, Colin McKenzie; Verster, Anna J.M.; Walker, Jane B. (Pretoria : The Government Printer, 1974)
    The pathological and parasitological findings from 100 free-ranging chacma baboons are described. One of the most striking discoveries was a heretofore unknown coccidian parasite, Isospora papionis, and even more important ...
  • The transmission of Babesia bovis using frozen infective material obtained from Boophilus microplus larvae 
    Van Vuuren, A.S.; Potgieter, F.T.; De Kock, V.E.; Bigalke, R.D.; Cameron, Colin McKenzie; Verster, Anna J.M.; Walker, Jane B. (Pretoria : The Government Printer, 1974)
    Boophilus microplus larvae infected with Babesia bovis were removed from a susceptible ox approximately 72 hours after attachment, triturated and stored in liquid nitrogen refrigerator with dimethyl sulphoxide as ...
