SYNOPSIS. The fine structure of the cilium, kinetosome, kinetodesmal fiber, and basal microtubules has been described in Cyathodinium piriforme. The ciliary axoneme is encased in an electron-dense jacket termed the axonemal jacket. This jacket surrounds the axoneme and is found midway between the axoneme and the ciliary membrane when viewed in cross section. Before division or reorganization the cilia are withdrawn into the cell. Intact cilia surrounded by their jackets are found in the… Expand

Asexual reproduction in the suctorianDiscophrya collini
TLDR
Discophrya collini reproduces asexually through the formation of a ciliated swarmer by evaginative budding and it is suggested that this evagination is induced by a rapid breakdown of supporting microtubules in the cavity wall and the subsequent hydrostatic pressure exerted by the body cytoplasm.

Ultrastructural features of Allantosoma intestinalis, a Suctorian ciliate isolated from the large intestine of the horse.
TLDR
Allantosoma intestinalis, a suctorian ciliate isolated from the intestine of the horse, was studied utilizing light and electron optical methods and its characteristics are compared with those of other suctorians. Expand
Scanning electron microscopy of budding and metamorphosis in Discophrya collini (Root).
Budding and metamorphosis in the suctorian ciliate, Discophrya collini, have been investigated by scanning electron microscopy. The adult body form, tentacles, stalk, and attachment disk areExpand
Cortical morphogenesis during the cell division cycle in Euplotes: An integrated study using light optical, scanning electron and transnlission electron microscopy

TLDR
Observations on the stages of morphogenesis give much new information about cortical development, particularly about proliferation and aggregation of kinetosomes (basal bodies), ciliary outgrowth, the topography of Morphogenesis, cirrus resorption, and growth of the pellicle. Expand
Ultrastructures and evolutionary modalities of flagellar and ciliary systems in protists
Summary— As both the ultrastructure and function of flagella and cilia have been for the main part remarkably conserved during Eukaryote, evolution, the question arises as to whether the variationsExpand
'Total evidence' refutes the inclusion of Perkinsus species in the phylum Apicomplexa.
TLDR
The phylogenetic affinities of the oyster pathogen Perkinsus marinus were investigated with morphology, 18S-like rDNA data and actin sequence data and the resulting cladogram strongly corroborates the placement of Perkinsus species with the Dinoflagellida and not with the Apicomplexa. Expand
The Action of Methylxanthines on Motility and Growth of Chlamydomonas reinhardtii and Other Flagellated Algae. Is Cyclic AMP Involved
Summary Methylxanthines, agents known to inhibit the activity of cyclic nucleotide phosphodiesterase, were employed to study the possible involvement of cyclic AMP in the control of growth andExpand
Chapter 12 – Protozoan Parasites
TLDR
This chapter discusses the protozoa which are according to the organ system or a part of the body most generally involved, and thus are under two main categories—parenteral and alimentary infections. Expand

The Somatic and Oral Infraciliature of the Enigmatic Giliate Cyathodinium piriforme
TLDR
It is suggested that a combination of fine structural and morphogenetic studies is required to elucidate both the form and the function of the several unique features of Cyathodinium and that a new understanding of these will permit resolution of the problem of the systematic status of the ciliate. Expand
The permanence of the infraciliature in suctoria: an electronmicroscopic study of pattern formation in Tokophrya infusionum.
TLDR
There is an organized infraciliature in Suctoria throughout their life cycle, and a distinct continuity of basal bodies across the generations, which serves as an anlage for the basal bodies and cilia that arise during embryogenesis. Expand
Budding and Metamorphosis in Acineta tuberosa. An Electron Microscopic Study on Morphogenesis in Suctoria
TLDR
All stages of the life cycle in Acineta tuberosa (Suctoria) were studied in the electron microscope and the results are discussed with respect to the morphogenetic potentialities of cortical structures in general. Expand
Cortical Structure in Nondividing and Cortical Morphogenesis in Dividing Oxytricha fallax
SYNOPSIS. Light- and electronmicroscopic observations of nondividing Oxytricha fallax revealed a high degree of cortical complexity in this species and provided much additional detail to previousExpand
Ultrastructural and other observations which suggest suctorian affinities for the taxonomically enigmatic ciliate Cyathodinium.
TLDR
Data obtained strongly suggest suctorian affinities for Cyathodinium, since a number of structures or features are strikingly reminiscent of similar structures recently discovered in ciliates belonging to the order Suctorida. Expand

TLDR
Observations on a second sequence of basal body formation suggest that the oral anlage arises by multiple duplication of somatic basal bodies. Expand
