Filamentous microorganisms were observed colonizing the cuticle of cyathostomes (Nematoda: Strongylidae) collected from the large intestine of Burchell's zebra (Equus burchelli antiquorum). Scanning (SEM) and transmission (TEM) electron microscopy revealed three filamentous microorganisms, designated as segmented, continuous multicellular, and helical. The segmented and continuous multicellular morphotypes each revealed a process of segmentation in their developmental stages, and those of the segmented filaments are demonstrated in this report. In contrast, the helical types of filaments appeared to be complexes of spiraling rodshaped organisms. In addition to these filaments, the cyathostome cuticle was also colonized by other smaller microorganisms.
丝状微生物被观察到定植在从大斑马（Equus burchelli antiquorum）大肠中收集的 Cyathostomes（Nematoda：Strongylidae）的角质层上。扫描（SEM）和透射（TEM）电子显微镜显示了三种丝状微生物，分别命名为分段、连续多细胞和螺旋形。分段和连续多细胞形态在其发育阶段都显示出分段过程，本报告中展示了分段丝状的形态。相比之下，螺旋形的丝状类型似乎是螺旋形杆状生物的复合体。除了这些丝状微生物外，Cyathostome 的角质层还被其他较小的微生物定植。
