De Vos, A.J. | Roos, J.A.
Theileria mutans, 4 isolates obtained from geographically distant parts of South Africa by subinoculation of infected blood were readily transmitted to cattle by Amblyomma hebraeum, all attempts to transmit these isolates with Rhipicephalus appendiculatus were unsuccessful

1981
Gray, J.S. | De Vos, A.J.
Babesia occultans n. sp. originally obtained from engorged female Hyalomma marginatum rufipes collected from cattle in Northern Transvaal, transmission studies in laboratory strain of ticks and splenectomized cattle, morphological, serological, and cross-immunity studies distinguished parasite as previously undescribed species highly infective for H. marginatum rufipes but of low virulence in cattle, unsuccessful attempt to transmit transovarially with Boophilus microplus

De Vos, A.J. | Potgieter, F.T.
Babesia bovis, B. bigemina, cattle, effect of tick control on infection rates and on enzootic stability, survey of farms from 6 geographical regions, control of ticks is not justified economically as means of minimizing risks of babesiosis outbreaks unless regular dipping is necessary to limit damage done by ticks per se
