Numbers of immature Trypanosoma brucei brucei within a tsetse midgut remain remarkably constant after establishment throughout the course of an infection, irrespective of whether the infection eventually matures. These results suggest a system of self regulation of the parasite population in the insect gut based on a form of programmed cell death which would carry advantages for both the parasite and the vector.
在整个感染过程中，采采蝇中肠内未成熟的布氏布氏锥虫数量在定殖后保持显著恒定，无论感染最终是否成熟。这些结果表明，昆虫肠道内的寄生虫种群存在一种自我调节系统，该系统基于一种程序性细胞死亡形式，这对寄生虫和传播媒介都有好处。
