| Popis: | Trypanosoma evansi, the agent of surra, is a salivarian trypanosome, originating from Africa. Surra is a major disease in camels, equines and dogs, in which it can often be fatal in the absence of treatment. Animals exhibit nonspecific clinical signs (anaemia, loss of weight and abortion). In the present survey, a blood sample was collected in Sousse (Central Tunisia) from a dog that presented clinical signs of trypanosomiasis. Giemsa-stained blood smears and PCR were performed. ITS1 sequences from blood had 99.8 and 99.5% homology with published T. evansi sequences from cattle and camels, respectively. To our knowledge, this is the first report of T. evansi in a Tunisian dog. Resume - Premier cas de surra (infection par Trypanosoma evansi) chez un chien en Tunisie. Trypanosoma evansi, l'agent du surra, est un trypanosome salivaria d'origine africaine. Le surra est une maladie importante chez le dromadaire, les equides et le chien, qui est souvent fatale en l'absence de traitement. L'animal presente des signes cliniques non specifiques (anemie, perte de poids, avortement). Dans la presente etude, l'echantillon de sang a ete preleve a Sousse (centre de la Tunisie) d'un chien presentant des signes cliniques de trypanosomose. Des etalements de sang colores au Giemsa et des PCR ont ete realises. Les sequences ITS1 avaient 99,8 et 99,5 % d'homologie avec des sequences de T. evansi, respectivement de bovins et de dromadaires. A notre connaissance, ceci est la premiere mention de T. evansi chez un chien en Tunisie. |
