Fig. 97.—Entamoeba histolytica, encysted form. progress show little differentiation from the grayish, finelygranular protoplasm. INTESTINAL PROTOZOA IN CLINICAL PRACTICE 409 At other times it is less active, progressing but little in anydirection. It becomes more or less rounded and throws offhyaline pseudopodia, only slowly to draw them back and toform others at some other point. The nucleus is generally very indistinct or hardly discern-able. Inclusions are frequently present, most often in the formof tissue fragments or red cells which appear to be engulfedunchanged. Under less favorable conditions complete roundingoccurs, and pseudopodia cease to form, in which condition theorganism may so closely resemble an epithelial cell as to beindistinguishable except by the finer staining methods. Cystsin this species are small spheric bodies with a definite cyst walland, when typically mature, contain four nuclei. There arealso often present thick rods or more irregular masses of chro-ma
