Tick-borne diseases are a major impediment to improved productivity of livestock in sub-Saharan Africa. Improved control of these diseases would be assisted by detailed epidemiological data. Here we used longitudinal, serological data to determine the patterns of exposure to Theileria parva, Theileria mutans, Babesia bigemina and Anaplasma marginale from 548 indigenous calves in western Kenya. ...

in order to develop a method for detecting and identification of theileria annulata, the specific primers from the major merozoite-piroplasm surface antigen sequence of theileria (tams1) were used to detect the t. annulata by nested-pcr technique. the assay provides a valuable tool for the identification of theileria annulata directly from clinical samples and enables determination of the infec...

The purpose of this study was to examine the potential application of Sorbitol, Sucrose and Gelatin in combination with glycerol in order to Theileria annulata infected cell line cryo-preservation. The efficiency of the freezing methods was compared by assessing the viability and plating efficiency of cells after resuscitation, dilution and equilibration in cell culture medium. As a result, the...

Hemoprotozoan infections often cause serious production losses in livestock. In the present study, we conducted a PCR-based survey of Babesia bovis, Babesia bigemina, Theileria annulata, Theileria orientalis, Trypanosoma evansi and Trypanosoma theileri, using 423 DNA samples extracted from blood samples of cattle (n=202), water buffaloes (n=43), sheep (n=51) and goats (n=127) bred in the Hue an...

BACKGROUND Equine piroplasmosis (EP) is the cause of persistent tick-borne infection with no symptoms, but the most important problem of EP is due to the persistent carrier state. Carrier animals to Babesia (Theileria) equi (Laveran 1901) and B. caballi (Nuttall, 1910) infestation could be identified by extremely sensitive PCR-based method. The purpose of this study was to identify the causativ...

Theileria annulata infects predominantly macrophages, and to a lesser extent B cells, and causes a widespread disease of cattle called tropical theileriosis. Disease-causing infected macrophages are aggressively invasive, but this virulence trait can be attenuated by long-term culture. Attenuated macrophages are used as live vaccines against tropical theileriosis and via their characterization ...

Despite having different cell tropism, the pathogenesis and immunobiology of the diseases caused by Theileria parva and Theileria annulata are remarkably similar. Live vaccines have been available for both parasites for over 40 years, but although they provide strong protection, practical disadvantages have limited their widespread application. Efforts to develop alternative vaccines using defi...

Theileriosis caused by parasites of the genus Theileria, is a vector-borne haemoprotozoan parasitic disease critical concern in small ruminants. This study aimed to explore infection status migratory Gaddi sheep and goats with from Theileria concurrence ectoparasite infestations using molecular methods. Seventy three apparently healthy animals were randomly sampled different flocks systematical...
