Abstract
An extracellular surface coat was observed at the fine-structural level on the outer lamina of the pellicular and flagellar membranes of intact Trypanosoma musculi bloodstream forms. The surface coat had a mean width of 9.2 nm, and was composed of a somewhat electron dense, uneven, fibrillar-like matrix. Brief trypsin treatment of living blood forms completely removed the cell surface coat.
摘要
在完整的肌肉锥虫血流形式的表膜和鞭毛膜的外层薄片上，在精细结构水平观察到一种细胞外表面被膜。该表面被膜平均宽度为9.2纳米，由某种电子密度较高、不均匀的纤维状基质组成。对活的血液形式进行短暂的胰蛋白酶处理可完全去除细胞表面被膜。
