“…Babesia bovis was evidenced in cattle in eastern BF, however its principal vector R. microplus (Dantas-Torres et al, 2012;Grisi et al, 2014), was not found there. This suggests cattle of eastern BF were infected with B. bovis after their exposure to R. microplus or other competent species, during their seasonal migration in northern BN through transhumance corridors (Zannou et al, 2020). However, this hypothesis requires more investigations considering cattle transboundary movements.…”

“…BN and BF are two countries sharing a border of 285 kms through which seasonal migrations of cattle occur in order to find pasture and watering places during the dry season. Such migrations favor the contact between herds mainly at grazing and watering places, raising the potential spread of transboundary diseases (Zannou et al, 2020). This transversal survey aims to assess the current situation of tick species and the associated pathogens in specific geographical locations corresponding to the departure (eastern BF) and arrival zones (northern BN) of the seasonal migration between the two countries.…”

Babesiosis, theileriosis, anaplasmosis, and heartwater are tick-borne diseases that threaten livestock production in sub-Saharan Africa including Burkina Faso and Benin. For over a decade, these two bordering countries have been facing an invasion of the livestock by the tick Rhipicephalus microplus, a major vector for babesiosis, accidentally introduced in Benin in 2004. The molecular identification of tick-borne pathogens in this border area is of particular interest due to animals seasonal migration between the two countries. In this survey, epidemiological features of ticks and tick-borne pathogens in cattle were investigated to compare the eastern Burkina Faso, corresponding to a seasonal migration departure zone, and the northern Benin, which represents a seasonal migration arrival zone. Ticks and peripheral blood were collected from a total of 946 cattle in the two areas. Ticks were morphologically identified and the DNA samples from bovine blood and ticks were analysed by Reverse Line Blot (RLB) hybridization process. A total of 2856 ticks were collected on 490 cattle in Burkina Faso, eight tick species were identified, while 3583 ticks were collected on 456 cattle in North Benin with nine tick species identified. The invasive tick, R. microplus was not found in eastern Burkina Faso, but its spread farthest north in Benin is reported. Six tick-borne pathogen species were found in cattle blood both in eastern Burkina Faso and in northern Benin. Ranked in decreasing order of overall prevalences, they are: Theileria mutans (91.1%), Theileria velifera (77.8%), Babesia bigemina (10.9%), Anaplasma marginale (4.2%), Babesia bovis (3.3%), and Theileria annulata (1.8%). To the best of our knowledge, this survey represents the first report of T. velifera and T. annulata in the region. Overall, the TBP prevalences were significantly higher in northern Benin than in eastern Burkina Faso, indicating a higher parasitological risk in this area.

“…This animal belongs to another herd which has also stayed in the same commune in Benin. According to the distribution of risk scores for the occurrence and establishment of R. microplus in the study area (Zannou et al, 2020), this commune appears to be one of the localities showing the highest risk scores (69-80%). As some transhumant herds stayed in the same commune, this could lead to suggest an infestation of more transhumant cattle by R. microplus, but which were not detected.…”

“…In the north of this country, the Atacora and Alibori departments receive a rainfall ranging from 700 to 1200 mm/year, which makes this region a suitable area for livestock farming and a favourite destination for Niger, Nigeria, Mali and Burkina Faso (BF) herders, seeking pasture and water points during the dry season (Lesse et al, 2015;Bouslikhane, 2015). After having walked between 150 and 200 km, farmers of eastern BF, coming from Gourma, Kompienga and Tapoa provinces, reach northern BN (Atacora and Alibori departments) through four transhumance corridors, and three entry points identified by Zannou et al (2020) (Fig. 1).…”

In West Africa, cross-border transhumance, also called seasonal migration, is known to be a very important animal production strategy, as it involves about 70 to 90% of cattle. In spite of the cattle movements, some strategic areas of transhumance remain poorly explored regarding ticks and their associated pathogens investigations. The purpose of this study is to evaluate the involvement of transhumance in the spread of cattle ticks and associated pathogens in Burkina Faso (BF) and Benin (BN), in a context of speedy invasion of West African livestock by Rhipicephalus microplus. A longitudinal survey was performed on 210 cattle from BF, monitored for ticks and tick-borne pathogens (TBP) during one seasonal transhumance. The first sampling coded "T0BF" took place in eastern BF, at the transhumance departure. A second sampling "T1BN" was carried out in northern BN, the transhumance arrival zone. A third sampling "T2BF" was done at the return of cattle in eastern BF. Ticks were morphologically identified and TBP detected with reverse line blot hybridization (RLB) assay. A total of 1027 ticks (7 species), 1006 ticks (11 species) and 1211 ticks (9 species) were respectively found at T0BF, T1BN and T2BF. Some species were collected at the three times of sampling without any significant difference in their relative abundances. However, other tick species appeared only at T1BN and/or T2BF. The TBP species found at the three points surveyed were Theileria annulata, Theileria mutans, Theileria velifera, Babesia bigemina and Anaplasma marginale. The most prevalent was T. mutans with 166/210 (79%), 159/210 (75.7%) and 78/210 (37%) cattle positive respectively at T0BF, T1BN and T2BF. Anaplasma centrale was evidenced with 0.5% and 0.9% respectively at T0BF and T2BF. To our knowledge, this represents its first report in the study area.Overall, the TBP prevalences were significantly lower at T2BF, highlighting the effect of tick populations changes induced by transhumance combined with the seasonal variation influence.
