“…Our observation of the dominance of H. dromedarii on cattle in Sokoto mirrors the findings by Lawal et al [56] and Onyiche et al [57], reporting H. dromedarii as the most prevalent (46.9%) [56] and the second most prevalent (42.3%) [57] tick species collected in camels from Sokoto. Interestingly, in the very recent survey by Onyiche et al [57], specimens of H. dromedarii tested positive for the presence of DNA of the Q fever agent Coxiella burnetii .…”

“…The rich diversity of tick species parasitising cattle encountered in this survey is generally in keeping with contemporary reports in Nigeria [8, 9]. As expected for sites in the Sahel, Hyalomma species dominated [51, 54–57]. While it represents the first investigation of this kind for the State of Zamfara, this study confirms the occurrence of five Hyalomma spp.…”

BackgroundTicks and tick-borne pathogens (TBPs) represent a significant economic burden to cattle farming in sub-Saharan Africa including Nigeria. However, in the northern part of this country, where the largest livestock population reside, little is known about the contemporary diversity of ticks and TBPs. This area is particularly vulnerable to climate change, undergoing marked transformation of habitat and associated flora and fauna that is also likely to include ticks. This study aimed to document the occurrence of tick species and Apicomplexan TBPs in cattle from North-Western Nigeria.MethodsIn 2017, ticks were collected from cattle in Zamfara and Sokoto States and identified morphologically. Additionally, a subset of ticks were screened molecularly for the detection of Apicomplexan DNA.ResultsA total of 494 adult ticks were collected from 80 cattle in Zamfara and 65 cattle in Sokoto State. Nine tick species were encountered, including seven Hyalomma spp. (i.e. Hyalomma dromedarii, Hyalomma impeltatum, Hyalomma impressum, Hyalomma marginatum, Hyalomma rufipes, Hyalomma truncatum and Hyalomma turanicum), Amblyomma variegatum and Rhipicephalus (Boophilus) decoloratus. All species were present in Zamfara, whereas only five species were found in Sokoto. Hyalomma rufipes was the most prevalent tick infesting cattle in Zamfara State (76.2%), while H. dromedarii was the most prevalent in Sokoto State (43.7%), confirming the widespread transfer of this species from camels onto livestock and its adaptation to cattle in the region.Of 159 ticks screened, 2 out of 54 (3.7%) from Zamfara State and 29 out of 105 (27.6%) from Sokoto State harboured DNA of Theileria annulata, the agent of tropical theileriosis.ConclusionsThis study confirms the presence of a broad diversity of tick species in cattle from North-Western Nigeria, providing the first locality records for Zamfara State. The occurrence of H. turanicum, recorded for the first time in Nigeria, indicates a distribution of this tick beyond Northern Africa.This study provides the first report for T. annulata in Nigeria. Given its enormous burden on livestock farming in North Africa and across Asia, further investigations are needed to better understand its epidemiology, vector transmission and potential clinical significance in cattle from Northern Nigeria and neighbouring Sahelian countries.

“…The fact that H. impressum was encountered on cattle in this study but not in the two aforementioned surveys on camels from Sokoto [56,57] may re ect a stronger host-speci city for cattle, although this conclusion is confounded by the low relative abundance of this species on the cattle we observed.…”
