Theileria parva, the most important bovine theilerial species in sub-Saharan Africa, causes
widespread mortality and morbidity in endemic areas. A survey was conducted using
buffy-coat specimens from 60 apparently healthy adult communally herded Nguni-type
cattle at the northeastern edge of the Hluhluwe-iMfolozi Park to determine, by means of
PCR and Reverse Line Blot (RLB) hybridisation, the occurrence of Theileria and Babesia
species. The presence of Trypanosoma species was determined using PCR-RFLP. Results
showed that 6.7%of the specimens were positive for Theileria parva. This significant finding
suggests that cattle in South Africa, and not only African buffaloes (Syncerus caffer), may be
subclinical carriers of T. parva. Other species identified were T. mutans (83.3 %), T. velifera
(70.0 %), Theileria sp. (sable) (46.8 %) and T. taurotragi (1.7 %). Two specimens (3.3 %) were
positive for Babesia bovis and single specimens (1.7 %) positive for B.bigemina and B. rossi,
respectively. Mixed infections, of up to 4 species, were common (65.0 %). Only 1 specimen
was found to be positive for Trypanosoma vivax, and 2 for T. theileri, of which only the first
species is pathogenic.

Buffalo-adapted Theileria parva causes Corridor disease in cattle. Strict control measures therefore apply to the movement
of buffalo in South Africa and include mandatory testing of buffalo for the presence of T. parva. ...
Theileria parva is the causative agent of Corridor disease in cattle in South Africa. The African
buffalo (Syncerus caffer) is the reservoir host, and, as these animals are important for eco-tourism in
South Africa, it ...

Eight cattle immunized with cattle-derived Theileria parva Boleni stabilate together with six susceptible controls were released in Dombawera Game Park on the Highveld of Zimbabwe. This coincided with Rhipicephalus ...
