Summary
A total of 2,895 sera collected between 1963 and 1983 from 41 different species of free-living wildlife in 11 African countries South of the Sahara was examined for serum neutralising antibodies to Akabane virus. Antibodies were demonstrated in 25 species including 16 species not previously reported to be susceptible to this virus. Results indicate that infection is widespread in Africa and has been present for a considerable time. The prevalence of antibodies suggests that some free-living species may act as reservoir hosts of infection in the wild.
Résumé
On a recherché les anticorps sériques neutralisant le virus Akabane sur 2.895 sérums récoltés entre 1963 et 1983 à partir de 41 espèces de la faune sauvage libre dans 11 pays africains au sud du Sahara. On a retrouvé des anticorps dans 25 espèces, dont 16 n'avaient pas encore été signalées comme sensibles à ce virus. Les résultats indiquent que l'infection est répandue en Afrique et qu'elle y est présente depuis un temps considérable. La prévalence des anticorps suggère que quelques espèces sauvages peuvent être des hôtes de l'infection dans la nature.
Resumen
Se examinaron 2,895 sueros para detectar anticuerpos contra el virus de Akabane, los cuales habían sido colectados entre 1963 y 1983 en 41 especies diferentes de animales salvajes. El muestreo incluyó 11 países africanos al Sur del Sahara. Se demostraron anticuerpos en 25 especies, incluyendo 16 especies las cuales no habían sido reportadas como susceptibles al virus. Los resultados indican que la infección está ampliamente difundida en Africa y que ha estado presente por tiempo considerable. La prevalencia de anticuerpos sugiere, que algunas especies de animales salvajes posiblemente actúan como reservorios del virus.
