La distribution et la dynamique des populations des tiques est un élément clé dans la connaissance des maladies transmises par ces vecteurs. C’est ainsi que cette étude a été conduite afin de mieux connaître l’épidémiologie de la Fièvre Hémorragique de Crimée-Congo (FHCC) dans les 8 communes du département de Boboye au Niger, où 355 sérums de bovins ont été collectés. En plus des sérums, des tiques ont été collectées sur 144 bovins, soit 18 par commune. Les sérums ont été soumis à un test ELISA (Enzyme Linked Immunosorbent Assay) indirect pour la détection d’anticorps anti-FHCC. Soixante-douze (72) éleveurs ont été interviewés sur leur connaissance de l’écologie des tiques, vecteurs du virus de la FHCC. Les résultats de l’enquête ont révélé que les éleveurs n’ont pas recours aux acaricides et que, dans leur majorité (55/72 soit 76,4 %), ils pratiquent la transhumance. L’étude a permis l’identification de 1342 tiques réparties en trois genres : Hyalomma (91,7%), Amblyomma (5,7%) et Rhipicephalus (Boophilus) (2,6%). La séroprévalence globale a été de 9,1±0,03%. Les communes de Harikanassou et Kiota ont été celles où les fortes prévalences ont été observées de 26,7 ± 12,9% et 22,5 ±12,9%. Le virus de la FHCC est en circulation chez la population animale, alors des investigations doivent être faites chez la population humaine.Mots clés : Anticorps anti-FHCC, Enzyme Linked Immunosorbent Assay Indirecte, Prévalence, Sérums, Tiques.   English Title: Crimean-Congo Hemorrhagic Fever (CCHF) ’s Epidemiology in cattle in Boboye’s department of Niger Republic To understand disease transmission by ticks, knowledge of population dynamics and distribution of these vectors are essentials. To sought that, the epidemiology of Crimean-Congo Hemorrhagic Fever (CCHF) in Niger Republic was studied by sampling 355 bovines (sera and ticks) in eight (8) local governments in Boboye’s department. Eighteen (18) bovines were sampled for ticks collection per local government making them a total of 144 bovine. Indirect ELISA test (enzyme-linked immunosorbent assay) was used to detect anti- CCHF antibodies. Seventy-two (72) farmers were surveyed on their knowledge on ticks’ ecology, main vectors of CCHF virus. The results revealed that farmers are not using acaricides, and their majority (55/72 thus 76.4%) practice Transhumance. The study allowed the identification of 1342 ticks distributed in 3 genus: Hyalomma (91.7%), Amblyomma (5.7%) and Rhipicephalus (Boophilus) (2.6%). The global seroprevalence against CCHF was (9.1 ± 0.03) %. Harikanassou and Kiota were the most affected local governments with respectively (26.7±12.9) % and (22.5±12,9) % prevalence. CCHV virus is circulating in animal population, so investigations must be made in human population.

ABSTRACT Antigen capture enzyme-linked immunosorbent assay (ELISA) is one of the most useful methods to detect Ebola virus rapidly. We previously developed an antigen capture ELISA using a monoclonal antibody (MAb), 3-3D, which reacted not only to the nucleoprotein (NP) of Zaire Ebola virus (EBO-Z) but also to the NPs of Sudan (EBO-S) and Reston Ebola (EBO-R) viruses. In this study, we developed antigen capture ELISAs using two novel MAbs, Res2-6C8 and Res2-1D8, specific to the NP of EBO-R. Res2-6C8 and Res2-1D8 recognized epitopes consisting of 4 and 8 amino acid residues, respectively, near the C-terminal region of the EBO-R NP. The antigen capture ELISAs using these two MAbs detected the EBO-R NP in the tissues from EBO-R-infected cynomolgus macaques. The antigen capture ELISAs using Res2-6C8 and Res2-1D8 are useful for the rapid detection of the NP in EBO-R-infected cynomolgus macaques.

ABSTRACT We developed a monoclonal antibody-based, antigen capture sandwich enzyme-linked immunosorbent assay (ELISA) for bovine coronavirus. We compared the ELISA with electron microscopy and the hemagglutination test and found a close correlation between them. The sensitivity of the ELISA was 104 bovine coronavirus particles per ml of 10% fecal suspension. Compared with electron microscopy, bovine coronavirus ELISA had 96% specificity.
