描述了来自致病锥虫的内吞生物体（来自唾液腺、神经节、内脏肌、血细胞、心包细胞、肾细胞、卵巢、睾丸和背侧血管）。它们被确定为革兰氏阴性细菌，并且它们类似于在昆虫中发现的其他细胞内共生体。所有标本的组织分布相似。中枢神经系统神经节和唾液腺中的胶质细胞是感染最严重的组织。即使是大规模感染也不会引起任何明显的致病作用。滋养细胞和卵母细胞无内吞细胞。尽管如此，内吞生物体的跨卵传播是从它们在胚胎肠腔中的存在推断出来的。在胚胎和第一幼虫期，器官没有内吞生物体。它们在第一次吸血和蜕皮后开始分散。病毒样颗粒在内吞生物体和宿主细胞中均被观察到。本文还讨论了内吞生物对寄主的可能影响。
Endocytobionts fromTriatoma infestansare described (from salivary glands, ganglia, visceral muscles, hemocytes, pericardial cells, nephrocytes, ovaries, testes, and dorsal vessel). They are determined as gram-negative bacteria and they resemble other intracellular symbionts found in insects. Tissue distribution was similar in all specimens. The glial cells in CNS ganglia and salivary glands are the most heavily infected tissues. Even massive infections do not cause any apparent pathogenic effect. The nurse cells and oocytes are without endocytobionts. Nonetheless, transovarial transmission of endocytobionts is deduced from their presence in embryonic gut lumen. In the embryo and first larval stage the organs are without endocytobionts. Their dispersal begins after the first blood meal and molting. Virus-like particles were observed in both the endocytobionts and the host cells. The possible influence of endocytobionts on the host is discussed.
