transmitted the trypanosome by introduction of infected mites per os to Serinus canaria. The presence of epimastigotes and metacyclic trypanosomes in 3 species of mites that are associated with moles and the growth of these flagellates to trypnomastigotes in culture at 37 C, which resemble the bloodstream form of T. talansmi ted the trypanosome by intr duction of ected mites per os to Serinus c naria. e presence of epimas igotes and metacyclic panosomes in 3 species of mites that are asciated with moles and the growth of these flalates to trypnomastigotes in culture at 37 C, pae, strongly suggest that mites are vectors. If so, this is the first evidence of mites acting as vectors of a mammalian trypanosome. Unfortunately, no experimental studies can be undertaken as moles do not survive for longer than 24 hr in the laboratory. ae, strongly suggest tha mites are vecto s.
