• The production of a basic immunity against pulpy kidney disease 

  Jansen, B.C.; Jansen, B.C. (Pretoria : The Government Printer, 1967)

  A single dose of alum-precipitated epsilon toxoid (APT) produces only a transitory immunity when given to fully susceptible sheep. A maximal immunity response is brought about by two injections each containing 90 Lf toxoid. ...
• Purification and physico-chemical characterization of Ecbo-virus type SA-I 

  Oellermann, R.A.; Els, H.J.; Verwoerd, D.W.; Jansen, B.C. (Pretoria : The Government Printer, 1967)

  Ecbovirus type SA-l, a bovine enterovirus, has been purified and crystallized and its chemical composition, physical characteristics and morphology studied. The virus particles have a mean diameter of 230Å, a sedimentation ...
• The serological relationship of South African bovine enterovirus strains (Ecbo SA-I and-II) and the growth characteristics in cell culture of the prototype strain (Ecbo SA-I) 

  Verwoerd, D.W.; Oellermann, R.A.; Broekman, J.; Weiss, K.E.; Jansen, B.C. (Pretoria : The Government Printer, 1967)

  A locally isolated bovine enterovirus designated echovirus SA-I was found to belong to the Weybridge serotype 134. The growth characteristics of the virus in a number of cell types were studied. Its replicative cycle and ...
• Studies on bovine ephemeral fever. I. Isolation and preliminary characterization of a virus from natural and experimentally produced cases of bovine ephemeral fever 

  Van der Westhuizen, B.; Jansen, B.C. (Pretoria : The Government Printer, 1967)

  Five immunologically identical strains of virus have been isolated from naturally and experimentally produced cases of ephemeral fever, by the intracerebral inoculation of suckling mice with infective buffy coat suspension. ...
• Arnold Theiler : an inspiring memory 

  Jansen, B.C. (Pretoria : The Government Printer, 1967)
• Alteration of reproductive function in the rat by cortisol acetate 

  Van Rensburg, S.J.; Cupps, P.T.; Jansen, B.C. (Pretoria : The Government Printer, 1967)

  The effects of cortisol acetate were studied on immature gonadotrophin treated rats, mature intact and hysterectomized cycling females, gestating and pseudopregnant subjects with pituitary implants, and mature males. ...
• A study of the effects of thyro-parathyroidectomy in young and mature sheep 

  Belonje, Peter Charles; Jansen, B.C. (Pretoria : The Government Printer, 1967)

  The effects of thyra-parathyroidectomy with subsequent thyroxin replacement have been studied in two young and two mature sheep. Observations made included the effects of the operation on the absorption, excretion and ...
• Contributions to the study of blood constituents in domestic animals in South Africa. 6. Normal values for serum protein fractions in sheep as obtained by electrophoresis on cellulose acetate strips 

  van Zyl, Lulu C; Jansen, B.C. (Pretoria : The Government Printer, 1967)

  Normal values for the various serum protein fractions of Merino sheep in South Africa have been established. Use was made of cellulose acetate membrane electrophoresis by the microzone technique and after processing the ...
• The use of the South African frog (Xenopus laevis) in the study of spinal reflex physiology 

  Holemans, K.C; Meij, Hester S.; Meyer, B.J.; Loots, J.M.; Jansen, B.C. (Pretoria : The Government Printer, 1967)

  The use of the South African frog (Xenopus laevis) in studies on spinal neurophysiology is introduced for the study of monosynaptic reflexes. Motorneurone excitability in this species may be measured by the classical ...
• Observations on the pathology of bilharziasis and other parasitic infestations of Hippopotamus amphibius Linnaeus, 1758, from the Kruger National Park 

  McCully, R.M.; Van Niekerk, J.W.; Kruger, S.P.; Jansen, B.C. (Pretoria : The Government Printer, 1967)

  Necropsies were conducted on 100 hippopotami during the winter of 1964 in an area of the Kruger National Park where the continuous drought, over a period of three years, had reduced food supplies to a very low level. ...
• Improved methods for the recovery of parasitic nematodes at autopsy
