Retrovirus-like particles were detected in venom glands from Bothrops jararacussu during electron microscopy. Type C-like particles were found inter- and intracellularly in gland and vessel lumina and scattered in the connective tissue. They were about 100 nm in diameter, with an electron dense core and bilaminar external membrane. Shapes suggestive of a budding process from the plasma membrane were also observed. Less frequently, type A-like particles, about 80 nm diameter with an electronlucent core, appeared in association with the membranes of the endoplasmic reticulum of the secretory cells.
在电子显微镜检查期间，在巴西矛头蝮蛇的毒腺中检测到逆转录病毒样颗粒。在腺体和血管腔的细胞间和细胞内发现了C型样颗粒，并散布在结缔组织中。它们直径约100纳米，具有电子致密核心和双层外膜。还观察到了提示从质膜出芽过程的形状。较少见的是，直径约80纳米、具有电子透明核心的A型样颗粒与分泌细胞内质网的膜相关联出现。
