    Encystment and Excystment of the Heterotrichous Ciliate Blepharisma stoltei Isquith (1968)

    Topics: Biology
    Notes: SYNOPSIS. The structure and cytochemistry of encystment and excystment of Blepharisma stoltei Isquith are described.The encystment process may be subdivided into 4 stages: (i) in the precystic stage the buccal apparatus overlaps about the posterior, (ii) in early encystment, the buccal apparatus is resorbed and an ectocyst is secreted, (iii) an interwall space, endocyst, and plug are secreted during late encystment, and (iv) the resting cyst stage typically has disc-like structures on the ectocyst, and a vacuole in the macronucleus.In excystment, 6 distinct stages may be defined: (i) partial kineties are formed in early excystment, (ii) permanent kineties give rise to anlagen of the buccal apparatus during stomatogenesis, (iii) the organism elongates and reforms the vegetative shape in late excystment, (iv) some cysts then divide, (v) the redeveloped organism is liberated thru the plug pore, and (vi) the postcystic stage resembles the vegetative form except for its size and lack of pigmentation.Cortical structures, extracellular membranes, and the macronuclear membrane are composed of protein-lipids. Unbound protein and RNA are found in the cytoplasm thruout the cystic cycle. DNA is present only in the nuclei. Polysaccharides, 1st found in the cytoplasm, are shifted to the plug in encystment. The plug material disappears during excystment, while PAS positive granules appear in the cytoplasm.

    A Redescription of Climacostomum virens (Ehrenberg) Stein and Proposal of a New Heterotrich Ciliate Family, Climacostomidae fam. n. (1972)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 19 (1972), S. 0 
    Details
    ISSN: 1550-7408
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: SYNOPSIS. Structure of the vegetative and asexually dividing forms of the large ciliate Climacostomum virens is redescribed with emphasis on stomatogenesis. These findings are discussed in relation to the taxonomic and possible evolutionary position of Climacostomum among heterotrichous ciliates. Comparative considerations of the buccal and somatic structures as well as of the stomatogenic patterns in this and other closely related ciliate genera indicate the need for placing Climacostomum and Fabrea in a new family, CLIMACOSTOMIDAE. The morphologic evidence suggests that Climacostomum may represent a line linking Fabrea and Stentor.

    Suitability of Selected Marine Algae for Growing the Marine Heterotrich Ciliate Fabrea salina (1983)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 30 (1983), S. 0 
    Details
    ISSN: 1550-7408
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: . Forty-five axenically grown algal (sensu lato) species representing six divisions—that is. 13 Chlorophyceae, 14 Chrysophycophyta, five Dinophycophyta, seven Cryptophycophyta, two Rhodophycophyta, and four Cyanochloronta—were aseplicaily presented separately as potential food sources to the marine helerotrich ciliate Fabrea salina under standardized algal number, medium, lighting, and temperature. The algae can be placed into three groups based on their effect on the intrinsic growth rate of the ciliate. Nutritious: Rhodomonas lens, cryptomonad LIS1, Dunaliella parva, Prasinodadus marinus, Chroomonas salina, D. tertiolecta, Chaeloceros galvestonensis, D. primolecta, Phaeodactylum tricornutum, D. salina, Isochrysis galbana, Cylindrothecaclosterium, cryptomonad strains M2, WH2 & FSA, Chroomonas sp., P. lubricus, and Peridinium trochoideum. Maintamers: Cyanobacterium strain Tigriopus blue green, P. triquetum. Monochrysis lutheri, Exuviella gracilis, Platymonas tetrathele. Cyclotella caspa, Crypthecodinium cohnii, Prasinocladus C5 strain, D. viridis, Nannochloris occulata, Tetraselmis gracilis, Anacystis marinum, Rhodosorus marinum, and Thalassiosira pseudonana. Nonnutritious: Stichococcus immobilis, Hymenomonas sp. strain 150, Syracosphaera sp. strain 181, Tetraselmis verrucosa, Thalassiosira fluviatilis, Microcoleus chthonoplastes, Synechococcus sp., Pavlova gyrans, Prymnesium parvum, Coccolithus huxleyi, Olisthodiscus luteus, Amphidinium carterii, and Porphyridium aerugineum. There was no apparent relationship between a given taxon and the nutritional value of the group, with the possible exception of the Cryptophycophyta.

    Suitability of Selected Bacteria and Yeasts for Growing the Estuarine Heterotrich Ciliate Fabrea salina (Henneguy) (1986)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: . Twenty-six species of bacteria and seven species of yeasts were aseptically presented separately as potential food sources to the estuarine heterotrich ciliate, Fabrea salina, under standardized conditions of cell number, medium, and temperature. The bacteria and yeasts were classified according to their effect on the intrinsic growth rate of the ciliate: Nutritious bacteria: Photobacterium fisherii, Vibrio neresis, V. natriegens, Flavobacterium sp. strain ASN16, V. harveyi, Xanthomonas sp. strain ASN22; Maintainer bacteria: V. vulnificus, Vibrio sp. strain V344, V. alginolyticus, V. anguillarum, Bacillus sp. strain ST332B2, Vibrio sp. strain V415, Acinetobacter sp. strain BHT8, Flectobacillus marinus, and Enterobacter aerogenes; Maintainer yeasts: Candida albicans and Cryptococcus marcerans strain 2; Nonnutriuous bacteria: V. parahaemolyticus, Planococcus sp. strain ASN13, P. mandapapanensis, Hyphomicrobium vulgari, Pseudomonas sp. strain CNS1, an unidentified gram-negative, yellow-pigmented, motile bacillus strain IG9A2, Thiobacillus thioparus, Escherichia coli, Corynebacterium sp. strain BR 17, Achromobacter sp. strain 23030, and Oceanospirillum beijerinckii; Nonnutriuous yeasts: C. marcerans strain 1, Saccharomyces cerevisiae, Debaryomyces hansenii, an unidentified black yeast, and C. laurentii. Under the conditions specified, bacteria appear to have a certain minimal value for the growth of Fabrea while yeast have little to none.

    The fine structure of the encysting salt marsh heterotrich ciliate Fabrea salina (1990)
    New York, NY : Wiley-Blackwell
    Journal of Morphology 205 (1990), S. 335-341

    Notes: Wall and internal organelles of the encysting salt marsh heterotrich ciliate Fabrea salina were examined by bright field and Nomarski interference contrast microscopy and by transmission and scanning electron microscopy. A mucoid sheath believed to be derived from bacteria covers the ectocyst. The possible bacterial origin of this sheath has been demonstrated experimentally by its removal and reappearence after 24 hours. Control ectocyst maintained in sterile seawater did not replace the sheath. The ectocyst has a crinkled appearance. The endocyst is composed of two layers. The inner endocyst material is continuous with that of the plug located at one end of the cyst. The two membranes are separated from one another by an interwall space filled with fibrous material. The cytoplasm, covered by an outer double membrane pellicle, contains mucocysts, pigment granules, microtubules, non-ciliated kinetosomes, Golgi complexes, ribosome-studded endoplasmic reticulum, and mitochondria. The endoplasm contains numerous autophagosomes, mitochondria, and food reserve materials. The macronucleus is centrally located in the cytoplasm of the encysting organism.
