Abstract
Trypanosoma vivax was isolated from cattle with natural infection in Raga city South of Sudan. It is denoted as DRSS06 (Deleba Raga South Sudan 2006). It was then used in the present study. The parasite was identified in the laboratory of Professor Ahmed Ali Ismail at College of Veterinary Medicine /Sudan University of Science and Technology based on its morphological character. A single polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) assay was used to confirm the T. vivax species.
The comparative characterization of T. vivax DRSS06 from Southern Sudan and T. vivax IRALD700 from Nigeria was done by using of Short oligodeoxyribonucleosite primers (10-mers) of arbitrary sequence in polymerase chain reaction (PCR) to generate genomic fingerprints (RAPD).
There was a similarity in the pathogenicity between the two strains. They had caused severe disease in goats and sheep with clinical signs as anaemia, loss of weight, poor condition, recumbency which culminating in death. However, there was no genetic similarity between the two strains.
