Abstract

This study was carried out in the imported camels that enter Egypt coming from Sudan those were passed on Abu-Simbuel region (Abu-Simbuel Abatoir) of Aswan Governorate, southern Egypt in the period from November, 2015 to October, 2016, to identify tick species infesting camels, study the prevalence of ticks infestation in camels all over the year andthe prevalence of Trypanosoma and microfilaria infection of camels, also the role of ticks in transmission of Trypanosoma species. The overall prevalence in the tick infestation was recorded as (60.96 %) (1463/2400) .The higher infestation were recorded in November, December (2015) and January (2016) and lower infestation were recorded in June.A total of (960) ticks were collected from the infested camels and identified. Hyalomma dromedarii was the predominant tick species and comprised (83.54 %) of the collected ticks. Other tick species found in very low numbers were Rhipicephalus praetextatus(4.27 %), Hyalomma anatolicum anatolicum(3.85%),Hyalomma impeltatum (2.92%), Rhipicephalus sanguineus (2.29 %),Hyalomma anatolicum excavatum(1.35 %), Hyalomma marginatum rufipes (1.12 %), and Hyalomma truncatum (0.63 %).(99) blood samples from (4800 )collected blood samples was infected by Trypanosoma evansi and hence constitute a prevalence rate of (2.0625%),with highest prevalence rate infection was (8.5 %) in October, alsofounded that (2) blood samples from( 4800) samples that infected by microfilaria in February and December (winter) with prevalence rate (0.042 %)(2/4800).We founded two samples in gut of male ticks contain developed stages of Trypanosoma in (March
and June).
