From the data obtained, a 10% inoculum size and an oxygen level of 6% seemed imperative for consistent growth, especially for the C. fetus venerealis strain. A lowered redox potential obtained by the addition of 0,1 % cysteine-HC1 to the media was stimulatory. The medium which yielded the best growth was the one described by Dennis & Jones (1959). The fastidious C. fetus venerealis strain yielded maximum values of 0,5 % packed cell volumes after 48 h cultivation in a microaerophilic atmosphere on this medium. The other strains yielded higher values.en©ARC - Onderstepoort and Faculty of Veterinary Science, University of Pretoria (original). ©University of Pretoria.
