Initial comparison of 2 polymorphic, immunodominant molecule (PIM) cDNA sequences from Theileria parva suggested that the PIM genes consist of conserved 5' and 3' termini flanking a central variable region. Further evidence is presented, based on sequence analysis, supporting this general structu...
Bacteriophage clones containing Theileria parva genomic DNA derived from two different telomeres were isolated and the nucleotide sequences of the telomeric repeats and adjacent telomere-associated (TAS) DNA were determined. The T. parva telomeric repeat sequences, a tandem array of TTTTAGGG or T...
Minisatellite tandem repeat elements are well known components of vertebrate genomes, but have not yet been extensively characterized in lower eukaryotes. We describe two unusual. AT-rich minisatellites of the protozoan parasite Theileria parva whose sequences are unrelated to the G/C-rich `chi m...
Polymorphic, multicopy gene families are frequently located in subtelomeric regions of the genomes of parasitic protozoa. Theileria parva telomere-associated (TA) DNA from two chromosomes contained long open reading frames (ORFs) 54% identical at the N-termini whose ends were 2670 and 2680 bp fro...
Two distinct genes encoding single domain, ATP-binding cassette transport protein homologues of Theileria parva were cloned and sequenced. Neither of the genes is tandemly duplicated. One gene, TpABCI, encodes a predicted protein of 593 amino acids with an N-terminal hydrophobic domain containing...
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) containi...
The nucleotide sequences of the large subunit ribosomal RNA coding genes within the two single copy ribosomal DNA transcription units of a cloned Theileria parva isolate from a buffalo were determined. The two LSU rRNA coding units differed by 11 nucleotide substitutions and two deletions of 1 an...
Theileria parva, a tick-transmitted protozoan parasite related to Plasmodium spp., causes the disease East Coast fever, an acute and usually fatal lymphoproliferative disorder of cattle in Africa. Previous studies using sera from cattle that have survived infection identified a polymorphic immuno...
