TLDR
The role of buffalo as a reservoir of cattle pathogenic theilerioses in East Africa is discussed with regard to tick feeding and cell culture results.Abstract:
245 buffalo from 13 areas of East Africa were examined for theilerial infections. The vast majority of buffalo (97.1%) examined had piroplasms in their erythrocytes. Theileria lawrencei was isolated from the buffalo by tick feeding and cell culture and was found to be common in most of these buffalo populations. Also over 50% of the buffalo had indirect fluorescent antibody (IFA) titres to T. lawrencei. T. mutans was only isolated from 3 buffalo populations but is probably common. Haematoxenus sp. was detected in the blood of 56% of the buffalo sampled. In the light of these results the role of buffalo as a reservoir of cattle pathogenic theilerioses in East Africa is discussed.read more

TL;DR: 6 oligonucleotide probes, corresponding to species-specific regions, were designed and demonstrated to provide unequivocal identification of each of the 6 species either by direct detection of parasite sr RNA or by hybridization to amplified parasite srRNA genes.

Integrated control of ticks and tick-borne diseases of cattle in Africa.
TL;DR: Methods of integrated control are suggested and discussed in light of recent development in control methods and those still under development and encouragement is given to attempt this approach in Africa to solve what must be the largest animal health problem of livestock remaining in the world.

Theileria parva: influence of vector, parasite and host relationships on the epidemiology of theileriosis in southern Africa.
TL;DR: It is hypothesized that vector population dynamics and the susceptibility of the vector population to infection with T. parva are among the most important factors which influence the expression of ECF as a disease entity, and the likelihood of transformation occurring.

Epidemiology of theileriosis in calves in an endemic area of Kenya.
TL;DR: Clinical episodes of T. mutans and T. parva infection were associated with febrile responses, enlarged lymph nodes, anaemia and other symptoms and about 80% of calves had poor weight gains or weight losses during either clinical infection.

The persistence of Theileria parva infection in cattle immunized using two stocks which differ in their ability to induce a carrier state: analysis using a novel blood spot PCR assay
TL;DR: An improved Theileria parva DNA detection assay based on the polymerase chain reaction (PCR) using primers derived from the 104 kDa antigen (p104) gene was developed, suggesting that the nature and persistence of the carrier state may differ markedly between different T. parva parasite stocks.
