	Introduction to the Ciliata
		They derive their name from the Latin word for "eyelash," which describes the appearance of many ciliates quite well: some or all of the surface of a ciliate is covered with relatively short, dense hairlike structures, the cilia, which beat to propel the ciliate through the water and/or to draw in food particles.
		Ciliates include some of the largest free-living protists; a few genera may reach two millimeters in length.
		Because individual ciliate species vary greatly in their tolerance of pollution, the ciliates found in a body of water can be used to gauge the degree of pollution quickly.

	NationMaster - Encyclopedia: Ciliate
		Ciliates tend to be large protozoa, a few reaching 2 mm in length, and are some of the most complex in structure.
		Ciliates are almost evenly distributed relative to depth during spring when stratification is moderate, phytoplankton stocks are vertically homogeneous, and oxygen concentrations in bottom waters are relatively high.
		Ciliate maxima in the upper estuary in late May 1988 may be directly related to high Chl a concentrations resulting from the mixed flagellate bloom in that area.

		Microphagous species dominated ciliate populations that were associated with the declining diatom bloom in early May 1988 and were also the major contributors to the spring maxima in the upper Bay during 1989, when a winter-spring phytoplankton bloom failed to develop.

	Breeder's Net
		While the culture of ciliates is not traditional for the home breeders they do appear to have useful applications, in so far as ciliates seem to have potential as a larval food or a bridging food item for marine fish and also as a planktonic food for some invertebrates.
		I have not had success with ciliates as a first food for marine fish larvae and I don’t know of anyone else that has had success with them, but this certainly does not mean that no one has been successful with ciliates or that it is not possible to utilize ciliates as a first food.
		And even if the ciliates cultured are of the right size and have adequate nutrition and are actually consumed by the larvae, bacterial and/or fungal contamination of the ciliates may destroy the ciliate culture and/or the larva within a day or two.

	Ciliates Physical Characteristics
		The ciliates are a large and diverse group of freshwater and marine organisms.
		Ciliates are multinucleate--that is, they possess at least one macronucleus and one micronucleus.
		Ciliates are covered by a cell membrane or pellicle, which may be very thin or may form a thickened armor.

		Ciliates were sampled at 10 sites, distributed around the lagoon to estimate lagoonal scale patches and at one grid, in the centre of the lagoon, to assess sub-lagoonal patches (1 to 200 m); samples were taken at these sites at 5 times through a year, covering the rainy and dry seasons.
		Ciliates were preserved with Lugol’s iodine; abundance and species composition were determined by standard inverted microscopy.
		The total ciliate diversity index was distributed in well-defined patches at different scales within the lagoon, and ranged from 0.1 to 1.9; 37 morphospecies occurred throughout the study.

	Wastewater ciliate
		Ciliated protozoa (ciliates) are an important component of the microbial community in aerobic biological wastewater-treatment plants with about 175 species reported.
		The advantage of using ciliates as bioindicators is that of speed, with an accurate prediction of effluent quality being available within an hour or two of sampling.
		Ciliates are rarely used on site in this way, however, mainly because of the difficulty that non-specialists have in identifying them.

		In the fermentation process according to the invention with continuous mass cultivation of ciliates (protozoa), the ciliate cells are cultivated in a complex axenic medium--free from living feed or prey organisms--and the biomass containing the desired biogenous valuable substances is obtained by continuous (permanent) cell extraction.
		Thus, the prejudice of those skilled in the art that ciliates are unsuitable for continuous mass cultivation with cell densities of several hundred thousand to millions of cells per ml using known fermenters and in the presence of the shear forces which are usually encountered, in axenic medium--i.e.
		The group of the ciliates which can be cultivated by the process described includes all taxonomic ciliate sub-groups which can be cultivated in principle in conventional standing and/or shaking cultures or batch fermentations on axenic nutrient media or nutrient media which comprise, as nutrient, the killed biomass of a feed organism.

	Ciliate Life Cycle
		The main issue in thinking about the ciliate life cycle is to understand that the cell is controlled by the macronucleus which is a somatic nucleus (that is, it is not involved in transmission of information across sexual generations).
		The life history of a ciliate typically looks like this: An initial period of sexual immaturiny during which cells can not mate is followed by a period of sexual maturity during which mating occurs readily.
		In oligohymenophoran ciliates like Tetrahymena or Paramecium the macronuclear DNA are very large and contain many gene loci, while in hypotrich ciliates, like Euplotes, the molecules are small and contain only one or a very few genes.

		Ciliate strap-lichen has ribbon-like lobes (3) that are ivory white in colour (5), with long fl projections at the edges (7).
		Ciliate strap-lichen reproduces asexually by producing microscopic structures called 'soredia'; masses of soredia look like a fine powder to the human eye, but actually consist of fungal threads (hyphae) and cells of the phycobiont (4).
		The causes of the decline of the ciliate strap-lichen in Great Britain are thought to be over-collecting, air pollution, fires, and trampling (3).

	Ciliates
		Ciliates are unicellular protists that can be recognised by their hairlike 'cilia'.
		Most ciliates are superb swimmers, some species are so fast that they are hardly visible when observed.
		Other ciliates have thick round bundles of cilia called cirri which act like legs and enable the organism to actually walk over a surface.

	Pathogens: Insect Pathogens: Protozoa: Ciliates
		Pathogenic ciliates penetrate the host and multiply in the hemocoel, although other tissues may be invaded.
		The mode of entry is unknown for most ciliate species; the mouth, cuticle, and wounds have been hypothesized (and verified in a few species) to be entry points (Clark and Brandl, 1976; Washburn et al., 1988).
		Biological Control: Because most ciliates are commensuals and because most pathogenic species do not cause fast, acute disease in their hosts, there has been little interest in using this group in biological control programs.

	Genetics
		As is typical of ciliates, the nuclear apparatus of Tetrahymena is composed of two structurally and functionally differentiated types of nuclei, a phenomenon known as nuclear dimorphism.
		Tetrahymena (and most Ciliates) are remarkably advanced among unicellular eukaryotes: no cell reproduction in the haplophase; differentiation of somatic and germ line nuclei; binary fission in the face of highly specialized compound cell structures; conjugation in diplophase; and internal fertilization at conjugation.
		The nuclear dimorphism of the ciliates is a remarkable phenomenon.
