一圈不完整的电力网被放置在未感染的牛和感染了锥虫的牛周围。用网捕到的已喂食和未喂食的苍蝇数量来评估感染和未感染的牛对采采蝇的吸引力，以及采采虫对牛的饲养成功率。感染和未感染的牛对梅毒螺旋体的吸引力没有差异。然而，梅毒螺旋体对感染牛的摄食成功率比对非感染牛高75%。这表明，弓形虫对牛行为或生理的某些影响通过增加媒介的饲养成功率来增加寄生虫的传播概率。导致这一结果的弓形虫对牛的影响的性质尚不清楚，但讨论了几种可能性。
An incomplete ring of electric nets was placed around uninfected cattle and cattle infected with Trypanosoma congolense. The numbers of fed and unfed Glossina pallidipes caught on the nets were used to estimate the attractiveness of infected and uninfected cattle to tsetse, and the feeding success of tsetse on the cattle. There was no difference in the attractiveness of infected and uninfected cattle to G. pallidipes. However, the feeding success of G. pallidipes on infected cattle was 75 % greater than on uninfected cattle. This suggests that certain effects of T. congolense on cattle behaviour or physiology act to increase the probability of transmission of the parasite by increasing the feeding success of the vector. The nature of the effects of T. congolense on cattle which caused this result is unknown, but several possibilities are discussed.
