Mixotrophy is the occurrence of phagotrophy and phototrophy in the same organism. In ciliates the intracellular phototroph can be unicellular green algae (zoochlorellae), dinoflagellates (zooxanthellae), cryptomonads or sequestered chloroplasts from ingested algae.

Surgical Neurology, 1985
A tumor of Rathke's cleft origin was studied, which showed some histologic features consistent with craniopharyngioma, but also had ciliated and mucin-containing cells more commonly observed in Rathke's cleft cysts. The combination of features provides further evidence that craniopharyngiomas and Rathke's cleft cysts have a common embryonic origin.

Ciliate evolution: The ribosomal phylogenies of the tetrahymenine ciliates
Journal of Molecular Evolution, 1989We have assembled and analyzed nucleotide sequences for several different rRNA components from tetrahymenine ciliates. These include previously published and some new 5S and 5.8S rRNAs for a total of 18 species. We also report sequences for some 30 species obtained by primer extension analysis of a region near the 5' end of the 23S rRNAs (region 580 ...

Procentrioles in ciliating and ciliated cells of chick trachea
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1972Electron microscopy of 16 to 18 day old chick tracheas revealed that procentrioles are present near the basal ends of the recently matured centrioles and basal bodies of both ciliating and ciliated cells. Cylinders 0.1 μ in outside diameter in which densely staining walls and a central axial filament can often be detected, are present between the ...

Our understanding of the biology of ciliate pheromones, and of the primary functions of the mating-type mechanism regulated by these molecules, has given rise to radical conflicts of opinion among different investigators, as regards interpretation of phenomena, definition of basic concepts, and use of terminology.

Chemical Signaling in Ciliates
Journal of Eukaryotic Microbiology, 1995ABSTRACT. For long, our knowledge of the biology of ciliate pheromones has long relied solely upon the study of the two structurally unrelated “gamones” identified in culture filtrates of a Blepharisma species. However, the characterization of a number of polypeptide pheromones secreted by Euplotes raikovi and E. octocarinatus has now established that

Symbionts of Ciliates and Ciliates as Symbionts
Indian Journal of MicrobiologyEndosymbiotic relationships between ciliates and others are critical for their ecological roles, physiological adaptations, and evolutionary implications. These can be obligate and facultative. Symbionts often provide essential nutrients, contribute to the ciliate's metabolism, aid in digestion, and offer protection against predators or environmental ...

This article includes information on two human parasites, one protozoan flagellate, Giardia lamblia, and one ciliate, Balantidum coli. Both are transmitted through ingestion of food and water contaminated with fecal material. G. lamblia may be the most common intestinal protozoan found in humans throughout the world and causes a wide range of symptoms,

Flow patterns around ciliated microorganisms and in ciliated ducts
Journal of Theoretical Biology, 1982Abstract Microscopic organisms and tracts of ciliated epithelia often generate complicated flow patterns such as eddies or jet-like phenomena. In addition, the presence of boundaries (e.g. microscope slide or coverslip) may also influence or severely restrict the resulting fluid motion.

Biotechnology in ciliates: an overview
Critical Reviews in Biotechnology, 2018Desde su descripción y clasificación en el siglo XIX, los ciliados han desempeñado un papel importante en la ciencia, lo que ha llevado a varios descubrimientos fundamentales en las áreas de la biología celular y molecular. Durante las últimas décadas, con el surgimiento de la biotecnología, también están saliendo a la luz muchos nuevos desarrollos. En
