    The pleural cavity of the Nile crocodile is divided into two separate cavities by means of a complete mediastinum. The pleural cavity contains the lungs, while the heart is situated in its own cavity, the pericardial ...
  • Ultrastructure of the epithelium of the rumen, reticulum and omasum of grey, white and black Karakul lambs 
    Groenewald, Hermanus B.; Verwoerd, Daniel Wynand (Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1993)
    Mortalities due to digestive disturbances occur in homozygous grey and white lambs after they have reached weaning age. Milk-filled, distended rumens, due to malfunctioning of the oesophageal groove, are found 24 h after ...
  • Rhipicephalus zambeziensis unlikely to transmit foot-and-mouth disease virus 
    Thomson, G.R. (Gavin); Blouin, E.; Potgieter, F.T.; Van Vuuren, C.DeW.J; Verwoerd, Daniel Wynand (Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1993)
    The potential of the ixodid tick, Rhipicephalus zambeziensis, was investigated as a vector in the transstadial transmission of the foot-and-mouth disease virus by feeding nymphae on viraemic (log 1,0-4,0 TCID₅₀/ml) cattle. ...
  • Molecular epidemiology of lyssaviruses : focus on the glycoprotein and pseudogenes

    The use of the polymerase chain reaction and sequencing of portions of lyssavirus glycoprotein and pseudogenes are discussed in attempts to better understand the epidemiology of rabies in Africa, the Americas and Europe.
  • Bat-eared fox behavioural ecology and the incidence of rabies in the Serengeti National Park 
    Maas, B.; Rabies in Southern and Eastern Africa. Workshop. (1993, Pretoria, South Africa); Verwoerd, Daniel Wynand (Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1993)
