The phylogenetic position of the Theileria buffeli group in relation to other Theileria species
Parasitology Research, 2002Theileria parasites known as either T. buffeli, T. orientalis or T. sergenti share many characteristics and are referred to as the T. buffeli group. The 18S ribosomal RNA and merozoite-piroplasm surface protein-encoding genes display a wider genetic variation within the T. buffeli group than between well defined species like T. annulata and T.

Infection of bovine monocyte/macrophage populations with Theileria annulata and Theileria parva
Veterinary Immunology and Immunopathology, 1989Infection and transformation of cells of the bovine immune system by Theileria annulata and T. parva were compared. Preliminary experiments with mammary gland macrophages indicated that they were permissive to infection by T. annulata but only to a limited extent by T. parva.

Chemotherapy of Theileria parva infection
Nature, 1976EAST coast fever (ECF), the most important tick-borne disease of cattle in eastern and central Africa, is caused by the protozoan parasite Theileria parva. No successful therapy is available and mortality can reach 96% (ref. 1), although large doses of tetracyclines have some prophylactic effect2.

Taking the Myc is bad for Theileria
Trends in Parasitology, 2005It is commonly acknowledged that intracellular parasites manipulate the survival pathways of the host cells to their own ends. Theileria are masters of this because they invade bovine leukocytes and immortalize them. Host-cell survival depends on the presence of live parasites, and parasite death results in the leukocyte undergoing programmed cell ...

Theileria parya: Kinetics of replication
Experimental Parasitology, 1969Abstract The kinetics of replication of Theileria parva (Muguga) in the bovine host were studied using infections produced by 10 1 , 10 2 , and 10 3 ticks. It was found that the growth of the organism was exponential from at least days 11–21 and probably from the start of growth in the bovine host.

Theileria orientalis in cattle in Ethiopia
Research in Veterinary Science, 1983The occurrence of Theileria orientalis in cattle in western Ethiopia was confirmed on morphological and serological grounds. The local vector remains unknown.

Theileria orientalis : a review
New Zealand Veterinary Journal, 2015Theileria orientalis (also known historically as T. sergenti and T. buffeli) is responsible for benign or non-transforming theileriosis, and exerts its major effect through erythrocyte destruction. The life cycle of T. orientalis is essentially similar to that of other Theileria species, except that the schizonts do not induce transformation and fatal ...

Antigens and immunity in Theileria annulata
Parasitology Today, 1988About 200 million cattle are believed to be at risk from the debilitating and often fatal effects of tropical theileriosis, caused by Theileria annulata. Currently, there is no very cheap effective drug for treatment of T. annulata infections, although the hydroxynophthoquinones parvaquone and buparvaquone are reported to give good results(1-4 ...

The lability of a bovine Theileria species
Experimental Parasitology, 1969Abstract A parasite, isolated from a steer that had undergone a clinical theileriasis episode 8 months previously, behaved like Theileria mutans. Further passages, with Rhipicephalus appendiculatus, resulted in changes which made the parasite indistinguishable from T. parva, the cause of East Coast Fever. Support is thus given for the suggestion that
