Naturally occurring infections of cattle with Theileria lestoquardi and sheep with Theileria annulata in the Sudan

First Molecular Identification and Genetic Characterization ofTheileria lestoquardiin Sheep of the Maghreb Region

“…Our work was carried out on 166 sheep in which we found two T. lestoquardi‐ positive animals (one adult and one yearling) giving a molecular prevalence of 1.2% (2/166). This prevalence is significantly lower compared with those found in Sudan (37.2%), Iran (19.6%) and Iraq (7.7%) (Zaeemi et al., ; Renneker et al., ; Taha et al., ). It is important here to report that the vector tick H. anatolicum is largely distributed in several arid regions in Africa (Tunisia, Libya, Egypt and Sudan) and Asia (Walker et al., ).…”

Variation in susceptibility of three Sudanese sheep ecotypes to natural infection with Theileria lestoquardi

“…The experiment was designed to study the limit of resistance, and susceptibility of three different sheep ecotypes originating from known disease free districts (Hassan and Salih, 2009), transferred to T. lestoquardi an endemic focus in Sudan (Taha et al, 2013) and maintained for 3 months under natural ticks challenge.…”

“…Atbara area, Sudan is a known endemic focus for T. lestoquardi (Taha et al, 2013), where, cattle, sheep and goats are kept under small-scale farming systems along River Nile and Atbara River banks where cash crops cultivation is practiced. The livestock kept in this farm system are continuously exposed to ticks throughout the year (FAO, 1983) in a situation where tick controls by regular acaricide spraying or by other control alternatives are rarely practiced.…”

“…The livestock kept in this farm system are continuously exposed to ticks throughout the year (FAO, 1983) in a situation where tick controls by regular acaricide spraying or by other control alternatives are rarely practiced. Atbara local sheep are invariably exposed to H. anatolicum infestations and T. lestoquardi infections (Taha et al, 2013). A farm with a history of recently diagnosed malignant ovine theileriosis (Anon., 2010) and abundant H. anatolicum was selected, and all the sheep kept were tested for T. lestoquardi infections.…”
