  • The construction of genomic libraries of Cowdria ruminantium in an expression vector, lambda gt11 
    Ambrosio, R.E.; Du Plessis, J.L.; Bezuidenhout, J.D.; Bigalke, R.D. (Published by the Government Printer, Pretoria., 1987)
    Genomic libraries of the Welgevonden and Kwanyanga isolates of Cowdria ruminantium have been constructed in an expression vector. These libraries contain approximately 4 x 10⁵ and 3 x 10⁵ recombinants respectively.
  • DNA probes for the detection of Anaplasma centrale and Anaplasma marginale 
    Visser, Elizabeth S.; Ambrosio, R.E.; Bigalke, R.D. (Published by the Government Printer, Pretoria., 1987)
    Anaplasmosis can be diagnosed either by immunological techniques or by direct microscopic examination of blood smears. Both methods are time-consuming and labour intensive. The use of DNA probes in an hybridization assay ...
  • The genome of Anaplasma : DNA base composition and DNA/DNA hybridization 
    Ambrosio, R.E.; Potgieter, F.T.; Bigalke, R.D. (Published by the Government Printer, Pretoria., 1987)
    The Tm value of DNA from Anaplasma centrale and Anaplasma marginale was found to be 87,1 °C and 89,3 °C, respectively. The G + C content, calculated from the Tm, was 45,1% for A. centrale and 48,5 % for A. marginale. ...
