“…In tick studies, DNA from R. africae has been found in Am. variegatum from Senegal, Benin, Mali, Côte d'Ivoire, Niger, Liberia, Guinea, Nigeria, and Burkina Faso [22][23][24][25][26][27][28][29][30][31][32][33], and in Amblyomma compressum from Liberia [26] (Table 1). Its DNA has also been found in a variety of other tick species including Hyalomma rufipes from Mali, Côte d'Ivoire, Guinea and Senegal [23,24,26,31], Hyalomma truncatum from Mali and Côte d'Ivoire [23,24], Hyalomma impeltatum from Nigeria [28], Hyalomma impressum from Côte d'Ivoire [24], Haemaphysalis paraleachi from Guinea [26], Rhipicephalus (Boophilus) annulatus from Senegal, Guinea, and Nigeria [21,26,30], Rhipicephalus evertsi evertsi from Mali, Senegal, and Nigeria [21,23,30], Rhipicephalus (Boophilus) decoloratus from Guinea and Nigeria, Rhipicephalus (Boophilus) geigyi, Rhipicephalus sanguineus s.l., and Rhipicephalus (Boophilus) microplus from Liberia, Nigeria, and Côte d'Ivoire, respectively [24,26,27,30], and recently in Rh.…”

Ticks are a significant group of arthropod vectors that transmit a large variety of pathogens responsible for human and animal diseases worldwide. Ticks are the second biggest transmitters of vector-borne diseases, behind mosquitoes. However, in West Africa, there is often only limited knowledge of tick-borne diseases. With the scarcity of appropriate diagnostic services, the prevalence of tick-borne diseases is generally underestimated in humans. In this review, we provide an update on tick-borne pathogens reported in people, animals and ticks in West Africa by microscopic, immunological and molecular methods. A systematic search was conducted in PubMed and Google Scholar. The selection criteria included all studies conducted in West Africa reporting the presence of Rickettsia, Borrelia, Anaplasma, Ehrlichia, Bartonella, Coxiella burnetii, Theileria, Babesia, Hepatozoon and Crimean–Congo haemorrhagic fever viruses in humans, animals or ticks. Our intention is to raise awareness of tick-borne diseases amongst human and animal health workers in West Africa, and also physicians working with tourists who have travelled to the region.

“…In Nigeria, though, some of these zoonotic SFG Rickettsiae species (R. africae, R. aeschlimannii, R. conorii subsp. israelensis and R. massilliae) had been reported [12,13,18,19,20,26,27,33] in ixodid ticks collected from animal hosts and vegetation, there hasn't been any record of Rickettsia species in humans. Generally, the information about the circulation and distribution of rickettsiae-infected tick species in Nigeria is scarce and fragmented.…”

Tick-borne Spotted Fever Group Rickettsioses (SFGR) is a serious disease reported in low income communities of many developed countries. The dearth of information on the existence of SFGR in most developing countries particularly in Sub Saharan Africa (SSA) including Nigeria, has been attributed to many factors chiefly amongst which are; poor knowledge of the disease, limitation of diagnostic capacity, leading to misdiagnosis and under reporting of some infectious zoonotic diseases such as SFGR. The aim of this study was to evaluate the pastoralists (livestock farmers) and animal health workers’ knowledge, attitudes and perceptions/practices towards ticks and tick-borne SFGR affecting livestock in 3 Local Government Areas (LGA): i.e., in Plateau State, Nigeria and including Jos the Capital City of the State. A total of 141 semi-structured questionnaires were administered to respondents including 90 pastoralists and 51 health workers from different veterinary clinics. Interestingly, the pastoralists expressed no knowledge about SFGR, although 61.36 % reported a history of tick infestation. Among the animal health workers, about 76.47 % expressed some knowledge about the disease, but lacked knowledge of the diagnosis of the disease. The findings indicate that there was the need for an increase awareness on SFGR and its predisposing factors among relevant stakeholders in the Plateau State, Nigeria.

Sub-Saharan Africa, with its hot and humid climate, is a conducive zone for tick proliferation. These vectors pose a major challenge to both animal and human health in the region. However, despite the relevance of emerging diseases and evidence of tick-borne disease emergence, very few studies have been dedicated to investigating zoonotic pathogens transmitted by ticks in this area. To raise awareness of the risks of tick-borne zoonotic diseases in sub-Saharan Africa, and to define a direction for future research, this systematic review considers the trends of research on tick-borne bacteria, parasites, and viruses from 2012 to 2023, aiming to highlight the circulation of these pathogens in ticks, cattle, sheep, goats, and humans. For this purpose, three international databases were screened to select 159 papers fitting designed inclusion criteria and used for qualitative analyses. Analysis of these studies revealed a high diversity of tick-borne pathogens in sub-Saharan Africa, with a total of 37 bacterial species, 27 parasite species, and 14 viruses identified. Among these, 27% were zoonotic pathogens, yet only 11 studies investigated their presence in humans. Furthermore, there is growing interest in the investigation of bacteria and parasites in both ticks and ruminants. However, research into viruses is limited and has only received notable interest from 2021 onwards. While studies on the detection of bacteria, including those of medical interest, have focused on ticks, little consideration has been given to these vectors in studies of parasites circulation. Regarding the limited focus on zoonotic pathogens transmitted by ticks, particularly in humans, despite documented cases of emerging zoonoses and the notable 27% proportion reported, further efforts should be made to fill these gaps. Future studies should prioritize the investigation of zoonotic pathogens, especially viruses, which represent the primary emerging threats, by adopting a One Health approach. This will enhance the understanding of their circulation and impact on both human and animal health. In addition, more attention should be given to the risk factors/drivers associated to their emergence as well as the perception of the population at risk of infection from these zoonotic pathogens.
