Concerted evolution of multicopy gene families in vertebrates is recognized as an important force in the generation of biological novelty but has not been documented for the multicopy genes of protozoa. A multicopy locus, Tpr, which consists of tandemly arrayed open reading frames (ORFs) containing several repeated elements has been described for Theileria parva. Herein we show that probes deri...

in an attempt to characterize theileria parva parasites circulating in south sudan cattle , polymerase chain reaction (pcr)-based assays were carried out using four single copy encoding antigen genes p104, pim, p150 and p67 in addition to one microsatellite ms321. a total of 20 bovine dna samples from two locations in south sudan were included in this study, in addition to two references strain...

Theileria is a genus of tick-borne protozoan that is globally widespread and infects nearly all ungulates in which they cause either latent infection or lethal disease. Wild animals are considered reservoir hosts of many species of Theileria and their diversity in wildlife species is increasingly becoming of interest. The molecular characterization and identification of Theileria infecting wild...

The recent transfer of Elthusa parva (Richardson, 1910) from Ceratothoa created a homonymy with Elthusa parva (Nierstrasz, 1915). Elthusa parva (Richardson, 1910) has priority and Elthusa nierstraszinom. n. is proposed as the new replacement name for the junior secondary homonym Elthusa parva (Nierstrasz, 1915).

Parasites have evolved a plethora of strategies to ensure their survival. The intracellular parasite Theileria parva secures its propagation and spreads through the infected animal by infecting and transforming T cells, inducing their continuous proliferation and rendering them metastatic. In previous work, we have shown that the parasite induces constitutive activation of the transcription fac...

East coast fever is a disease of cattle caused by Theileria parva and is transmitted by the tick Rhipicephalus appendiculatus. Buffalos are a natural reservoir of the parasite. The objectives of this study were to determine the T. parva infection in buffalo and cattle field samples, to identify genotypes of T. parva infecting cattle and buffalo and finally to investigate the presence of buffalo...

A cross-sectional study was conducted between September and October 2010 in five states of South Sudan that were selected on the basis of the perceived risk of tick-borne diseases. The purpose was to investigate epidemiological parameters of tick-borne diseases in South Sudan and their uses in future control strategies. A total of 805 calves were assessed by clinical, microscopic and serologi...

Respiratory failure and death in East Coast Fever (ECF), a clinical syndrome of African cattle caused by the apicomplexan parasite Theileria parva, has historically been attributed to pulmonary infiltration by infected lymphocytes. However, immunohistochemical staining of tissue from T. parva infected cattle revealed large numbers of CD3- and CD20-negative intralesional mononuclear cells. Due t...
