Abstract

The ciliated protozoan, Terebrospira chattoni, invades the exoskeleton of the shrimp, Palaemonetes pugio, eating out long galleries parallel to the surface of the exoskeleton. Solubilization of the exoskeleton occurs around an area of the elaborately infolded surface membrane at the anterior of the organism. Dissolved products of the digestion of the exoskeleton are taken into the body by the formation of coated vesicles at pores in the membrane. The surface membrane that is taken in by pinocytosis is apparently recycled by the introduction into the membrane of organelles implicated in membrane recycling in other ciliates. Acid phosphatase can be demonstrated on the surface membrane as well as in the endocuticle around the organism.

摘要

纤毛原生动物查氏管刺虫侵入虾（海湾褐虾）的外骨骼，在与外骨骼表面平行的方向吃出长长的通道。外骨骼的溶解发生在该生物体前部精心折叠的表面膜区域周围。外骨骼消化产生的溶解产物通过在膜孔处形成有被小泡进入体内。通过胞饮作用摄取的表面膜显然通过引入其他纤毛虫中与膜循环有关的细胞器而被循环利用。酸性磷酸酶可以在表面膜以及生物体周围的内表皮中检测到。
