虽然彭亨丝虫和魏氏棘唇线虫表现了明显的厌氧代谢,但它们也象好氧的棉鼠丝虫一样,具有明显内脊的线粒体。甚少从这些线粒体的形态上可以推测有某种需氧代谢的存在。为了搞清楚为什么这3种丝虫中只有棉鼠丝虫表现了需氧要求并且积累了较多的醋酸,作者对3种丝虫利用丙酮酸进行了比较研究,采用标记丙酮酸孵育的方法检验了每种丝虫利用丙酮酸盐的能力,并鉴定了代谢的最终产物。棉鼠丝虫和彭亨丝虫成虫是分别从感染 Although the filaments of Paenconian and Lipomyces piniperus show distinct anaerobic metabolism, they are also mitochondria with distinctly internal ridges, like aerobic cottonflies. There is little speculation about the existence of some aerobic metabolism from the morphology of these mitochondria. In order to find out why only three of the three filarial worms exhibited aerobic requirements and accumulated more acetic acid, the authors compared the use of pyruvate for three species of filarial filaments and the method for labeling with pyruvate The ability of each filamentous worm to utilize pyruvate was identified and the metabolic end product was identified. The adults of cotton rat filariasis and penicilli filariasis were infected separately
