Intracellular bacteria in ciliates
International Microbiology, 2001Ciliates are frequently colonized by other micro-organisms. The large size of ciliate cells offers habitats for hundreds to thousands of bacteria in different compartments, such as cytoplasm, nuclei and even perinuclear spaces. Size, phagocytic feeding habit and other features appear to be favorable pre-adaptations of ciliates for symbiosis with ...

Hydrogenosomes of Anaerobic Ciliates
2008Ciliates are highly complex unicellular eukaryotes. Most of them live in aerobic environments and possess mitochondria. However, in several orders of ciliates, anaerobic species evolved that contain “hydrogenosomes”, organelles that produce hydrogen and ATP.

Ciliates are characterized by the occurrence of two different cell nuclei. The DNA-rich macronucleus is the “somatic nucleus” of the cell and is responsible for almost the entire cellular RNA synthesis. However, during sexual reproduction, or conjugation, it is resorbed. The diploid micronuclei are the “germ line nuclei” of the cells.

From a biomineralization point of view, the protist world is far less investigated than its metazoan counterpart. However, eukaryotic single-celled organisms offer a very unique access to discover biomineralization mechanisms in vivo. With respect to intracellular mechanisms involved in ion enrichment, mineral transport or vesicle formation ciliates ...

Archives of Dermatology, 1978
To the Editor.— Farmer and Helwig 1 described 11 female patients with cutaneous ciliated cysts in the lower extremities. They quoted only two previously reported cases. The first patient described by Hess in 1890 2 was a 15-year old-girl with a ciliated cyst situated over the fourth or fifth thoracic vertebra and because of this anatomic situation ...

The American Naturalist, 1941
A FEW years ago Jahn (1934), in a discussion of problems of population growth in the protozoa, stated that a mathematical analysis of most of the data concerning growth of protozoan populations would not appreciably increase our understanding of the matter because, in most of the investigations in this field, the various factors which might affect the ...
