Molecular Identification and GeneticCharacterization of <i>Trypanosoma Evansi</i>from Cattle in Makkah, Saudi Arabia

Trypanosoma evansi (T.evansi), a haemoprotozoan parasite, is the causative agent of surra or trypanosomiasis in tropical and subtropical regions and affects a wide range of domestic and wild animals, including cattle, camels, horses, and various wildlife species [1-3].T. evansi is a serious and potentially fatal disease causing substantial economic losses in animal production due to decreased productivity, and loss of weight.Furthermore, T. evansi has been linked to failure in vaccination, which can substantially impact global trade in live animals and their products, in addition to the widespread utilization of trypanocides [4][5][6].Globally, it has been reported in Africa, Asia, Europe, and South America that the susceptibility to T. evansi infection differs among host species, and the prevalence varies geographically [5].In Asia, T. evansi is prevalent in the Arabian Peninsula, including Saudi Arabia, the United Arab Emirates, Jordan, Lebanon, Syria, Iraq,.Diagnosis of T. evansi can be challenging due to the intermittent presence of the parasite in the bloodstream and low parasitemia due to early or chronic infections
