Trypanosomoses humaines et animales: maladie du sommeil et Nagana

https://doi.org/10.1016/S0924-4204(99)80021-3Get rights and content

Les trypanosomes africains, dont la plupart sont transmis par les glossines ou mouches tsétsé, déterminent à la fois la maladie du sommeil et des affections d'une grande importance économique chez les animaux domestiques. Cette revue présente les connaissances actuelles sur les trypanosomes et les trypanosomoses. L'accent est mis sur les particularités biologiques de ces parasites, et sur les réponses immunitaires à l'infection. Si certaines particularités biologiques, telles que la variation antigénique, constituent des mécanismes d'échappement aux défenses de l'hôte, d'autres sont en revanche des points d'attaque potentiels pour le développement de nouvelles thérapeutiques.

      Animal African Trypanosomosis (AAT or Nagana) is a severe vector-borne disease caused by protozoan parasites belonging to the Trypanosomatidae family and usually cyclically transmitted by blood-sucking tsetse flies (Authié et al., 1999).

      Citation Excerpt :

      Trypanosoma spp. and Leishmania spp. are protozoan parasites of the Trypanosomatidae family (order Kinetoplastida). Some species in these genera are responsible for diseases in humans and animals: Human and Animal African Trypanosomoses (sleeping sickness and Nagana, respectively) (Authié et al., 1999), American Trypanosomiasis (Chagas disease), and Leishmanioses. All are vector-borne diseases labelled as “neglected” by WHO (http://www.who.int/neglected_diseases/diseases/en/) (Alvar et al., 2012; Aksoy et al., 2017; Roger et al., 2017).
