Tropical Animal Health and Production Aims and scope Submit manuscript

Summary

In two distinct areas of East Africa 28,238 and 16,303 non-teneral flies respectively were caught. Infected probosces containing mature trypanosome infections were macerated and inoculated into laboratory animals. Differences in the transmission of trypanosomes existed between different species of tsetse fly. The effect on transmission of trypanosome infection rate in the fly and species of host on which the flies fed is discussed. A method to estimate trypanosome challenge is proposed.

Résumé

On a capturé dans deux régions différentes de l'Afrique de l'Est respectivement 28.238 et 16.303 mouches ayant pris au moins un repas. Les trompes infestées, contenant des trypanosomes métacycliques, ont été macérées et inoculées á des animaux de laboratoire. Il existait des différences dans la transmission de trypanosomes entre différentes espéces de glossines. L'effet sur la transmission du taux de l'infection á trypanosomes chez la mouche et l'espèce d'hôte sur lequel les mouches s'étaient nourries est discuté. On propose une méthode pour estimer l'intensité des inoculations trypanosomiennes.

Sumario

Se atraparon 28,238 y 16,303 moscas tsetse respectivamente en dos areas didtintas de Africa Oriental. Se maceraron proboscis infectadas con tripanosomas maduros y fueron inoculadas en animales de laboratorio. Existieron diferencias en la trasmisión de tripanosomas entre las distintas especies de moscas tsetse. Se discute el efecto obtenido sobre la transmisión por el grado de infección con tripanosomas en la mosca y en hospederos de los cuales la mosca se alimenta.
