  • Characterization of eight rough mutants of Salmonella gallinarum 
    Cameron, Colin McKenzie; Fuls, W.J.P.; Van Reenen, Lucille; De Kock, V.E.; De Lange, M.; Bigalke, R.D.; Howell, P.G.; Reinecke, R.K. (Published by the Government Printer, Pretoria, 1972)
    The cultural, serological and immunological properties of eight rough mutants of S. gallinarum were compared with the parent smooth strains as well as with a reference rough mutant (S. gallinarum strain 9R). The rough ...
  • A comparative study on the immunogenicity of live and inactivated Salmonella typhimurium vaccines in mice 
    Cameron, Colin McKenzie; Fuls, W.J.P.; De Kock, V.E.; Bigalke, R.D.; Cameron, Colin McKenzie; Verster, Anna J.M.; Walker, Jane B. (Pretoria : The Government Printer, 1974)
    Mice were very successfully immunized against intraperitoneal infection with virulent Salmonella typhimurium by fluid and lyophilized formalin inactivated vaccines prepared from a smooth strain of the microorganism. A ...
  • Composition and evaluation of the efficacy of a Staphylococcus aureus vaccine 
    Cameron, Colin McKenzie; Fuls, W.J.P.; Botha, Wilna F.; Steyn, P.J.J.; Bigalke, R.D.; Morren, A.J.; Verster, Anna J.M.; Verwoerd, Daniel Wynand; Walker, Jane B.; Cameron, Colin McKenzie; Gilchrist, Frances M.C. (Published by The Government Printer, Pretoria, 1979)
    An alum-precipitated Staphylococcus aureus vaccine, composed of a formalin-inactivated whole culture of a strain which produces Smith surface antigen and combined with the whole culture of a highly toxigenic strain, was ...
  • The effect of immunosuppression on the development of immunity to fowl typhoid 
    Brett, O.L.; Fuls, W.J.P.; Cameron, Colin McKenzie; De Kock, V.E.; Verster, Anna J.M.; Walker, Jane B.; Bigalke, R.D.; Cameron, Colin McKenzie (Pretoria : The Government Printer, 1974)
    Chickens which were given cyclophosphamide during the first three to five days of life showed a marked depression in their humoral antibody response to sheep erythrocytes and Brucella antigen. Their ability to develop ...
  • Failure to induce in rabbits effective immunity to a mixed infection of Fusobacterium necrophorum and Corynebacterium pyogenes with a combined bacterin 
    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. (Pretoria : The Government Printer, 1977)
    Rabbits were immunized with alum-precipitated, oil adjuvant and an untreated bacterin composed of F. necrophorum and C. pyogenes. Immunized rabbits were challenged intradermally with a mixture of F. necrophorum and C. ...
  • Immune response to dead and live Eschericia coli vaccines and colostral transfer of immunity to calves and lambs 
    Cameron, Colin McKenzie; Fuls, W.J.P.; 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)
    Administration of a single injection of killed polyvalent Escherichia coli (Migula, 1895) vaccine to ewes and cows resulted in a marked increase in the mouse protective properties of their sera. Antibodies were effectively ...
  • 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 ...
  • Immunization of mice and guinea-pigs against Salmonella dublin infection with live and inactivated vaccine 
    Cameron, Colin McKenzie; Fuls, W.J.P.; De Kock, V.E.; Bigalke, R.D.; Cameron, Colin McKenzie; Verster, Anna J,M.; Walker, Jane B. (Published by The Government Printer, Pretoria, 1975)
    The immunogenicity of a number of avirulent rough Salmonella dublin mutants was compared in mice and guinea-pigs. Live vaccine prepared from Strain HB 1/17 at doses of 5 x 10⁷ per mouse usually gave an immunity of between ...
  • Method of production of and antibody response to an oil adjuvant Bacteroides nodosus bacterin 
    Fuls, W.J.P.; Cameron, Colin McKenzie; 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, 1978)
    A procedure is described for the production of a highly concentrated Bacteroides nodosus bacterin. An oil adjuvant bacterin which elicited the best antibody response in rabbits produced a response in sheep which lasted for ...
