Culicoides nubeculosus, vecteur expérimental d'un nouveau trypanosome de psittaciforme: Trypanosoma bakeri n. sp.

Abstract

Two out of four Psittacula roseata from Thaïland harboured a trypanosome: T. bakeri n. sp. Laboratory reared Culicoides nubeculosus were fed on one of them. The trypanosomes developed well in this arthropod and metatrypomastigotes were observed five days after the blood meal. The inoculation of crushed Culicoides into one of the trypanosome-free Psittacula gave rise to a parasitaemia after a prepatent period of eleven days. This provides more evidence that Culicoides can act as vectors of avian trypanosomes.
