Abstract

The ultrastructural changes occurring during encystment of acanthamoeba palestinensis have been investigated. The cyst wall consists of endocyst and exocyst, both having the same fine structure. At irregular intervals in the cyst wall ostioles occupied by opercula are present. The nuclear membrane forms bulb-shaped projections and releases vesicles bounded by double membranes into the cytoplasm. Dense nucleolus-like bodies of different sizes and variable numbers are found in the nucleus of every cyst. The importance of the cyst structure as a taxonomic criterion is discussed.

摘要

对巴勒斯坦棘阿米巴包囊形成过程中的超微结构变化进行了研究。囊壁由内膜和外膜组成，二者具有相同的精细结构。在囊壁上，以不规则的间隔存在着被盖瓣占据的小孔。核膜形成球状突起，并将由双层膜包裹的囊泡释放到细胞质中。在每个包囊的细胞核中发现了不同大小和数量不等的致密核仁样小体。讨论了囊结构作为分类标准的重要性。
