I N ALL species of the genus Colpoda reproduction normally takes place within a cyst wall. This wall is secreted by the ciliate during the early phases of mitotic activity and is accompanied by a rounding-out of the cell. Within the division cyst two daughter-cells are produced, and these divide again to produce four cells. There is a gradual redifferentiation of the characteristic morphological structures of the trophic ciliate in each daughter, swimming activities become more and more…

How Do Cysts Know When to Hatch? The Role of Ecological Communication in Awakening Latent Life

TLDR
The role of cysts (and their awakening signals) in the pathogenicity of human parasitic protozoan diseases: Giardia, Plasmodium, Toxoplasma, Cryptosporidium, Balantidium, and Entamoeba are discussed.

THE NUTRITION OF THE PROTOZOA

TLDR
Within the phylum there exist chlorophyll‐bearing, plant‐like forms and numerous intermediary types up to and including those requiring living particulate food, thus providing the full range of nutritional types, but none of those proposed is adequate.

Growth Studies on Ciliates. I. The Role of Bacteria in the Growth and Reproduction of Colpoda

TLDR
The purpose of this report is to detail the experiments carried on for well over a year and show the necessity of, and the consequences of, a precise method for bacterial control in dealing with the culture methods for studies of ciliate metabolism in general.

CYTOLOGICAL INVESTIGATIONS OF COLPODA CUCULLUS

TLDR
A complete description of the nuclear activity of Colpoda cucullus Muller is given for the first time and it is shown that when cultural conditions are poor resistant cysts are formed.

Growth Studies on Ciliates. II. The Food Factor in the Growth, Reproduction, and Encystment of Colpoda

TLDR
The experiments to be reported here were designed to determine quantitatively the potentialities of growth of the ciliate Colpoda in distilled water bacterized with the coliform organism Aerobacter, and to show that survival and growth may vary depending upon the initial number of protozoa used.
