在实验室饲养的感染刚果锥虫或间日锥虫的舌虫中，锥虫定植于肠管以及中肠和/或长鼻。野外捕获的采采蝇也感染刚果锥虫和间日锥虫。刚果锥虫 cibarial 感染发生在所检查的所有舌甲物种中：G. tachinoides、G. palpalis palpalis、G. morsitans morsitans 和 G. m.下莫尔西坦。 T. vivax 仅存在于 G. tachinoides 的囊中。扫描电子显微镜显示，锥虫牢固地附着在容器中。两种野外捕获的 G. tachinoides 也被发现仅有 cibarial 感染，推测是间日毛虫 (T. vivax)。需要更多有关 Glossina 中脊椎感染发生情况的信息，尤其是在野外。建议对果蝇进行检查，作为现场采采蝇常规解剖的一部分。
In a percentage of laboratory bred Glossina infected with Trypanosoma congolense or T. vivax, trypanosomes colonized the cibarium as well as the midgut and/or the proboscis. Field-caught tsetse flies also had T. congolense and T. vivax cibarial infections. T. congolense cibarial infections occurred in all species of Glossina examined: G. tachinoides, G. palpalis palpalis, G. morsitans morsitans and G. m. submorsitans. T. vivax was only found in the cibarium of G. tachinoides. Trypanosomes were firmly attached in the cibarium, as shown by scanning electron microscopy. Two field-caught G. tachinoides were also discovered to have only cibarial infections, presumably of T. vivax. More information is required on the occurrence of cibarial infections in Glossina, especially in the field. It is suggested that examination of the cibarium should be carried out as part of the routine dissection of tsetse flies in the field.
