TLDR
The present scheme is a considerable revision of the Society's 1964 classification, and it is hoped that the present classification incorporates most of the major changes that will be made for some time, and that it will be used for many years by both protozoologist and non-protozoologists.Abstract:
The subkingdom Protozoa now inclues over 65,000 named species, of which over half are fossil and approximately 10,000 are parasitic. Among living species, this includes approximately 250 parasitic and 11,300 free-living sarcodines (of which approximately 4,600 are foraminiferids); approximately 1,8000 parasitic and 5,100 free-living flagellates; approximately 5,600 parasitic "Sporozoa" (including Apicomplexa, Microspora, Myxospora, and Ascetospora); and approximately 2,5000 parasitic and 4,700 free-living ciliates. There are undoubtedly thousands more still unnamed. Seven phyla of PROTOZOA are accepted in this classification--SARCOMASTIGOPHORA, LABYRINTHOMORPHA, APICOMPLEXA, MICROSPORA, ASCETOSPORA, MYXOSPORA, and CILIOPHORA. Diagnoses are given for these and for all higher taxa through suborders, and reporesentative genera of each are named. The present scheme is a considerable revision of the Society's 1964 classification, which was prepared at a time when perhaps 48,000 species had been named. It has been necessitated by the acquisition of a great deal of nex taxonomic information, much of it through electron microscopy. It is hoped that the present classification incorporatesmost of the major changes that will be made for some time, and that it will be used for many years by both protozoologist and non-protozoologists.read more

TL;DR: This revision of the classification of unicellular eukaryotes updates that of Levine et al. (1980) for the protozoa and expands it to include other protists, and proposes a scheme that is based on nameless ranked systematics.
Journal ArticleDOI
Biology of Giardia lamblia.
TL;DR: The Giardia genome project promises to greatly increase the understanding of this interesting and enigmatic organism.
Book
The Rumen Protozoa
TL;DR: In addition to the bacteria in the rumen there are many larger organisms which at various times have been designated protozoa, of which there are two groups both in the subclass Trichostomatia and the entodiniomorphs.
Journal ArticleDOI
Kingdom protozoa and its 18 phyla.
TL;DR: The demarcation of protist kingdoms is reviewed, a complete revised classification down to the level of subclass is provided for the kingdoms Protozoa, ArchezoA, and Chromista, and the phylogenetic basis of the revised classification is outlined.
Book ChapterDOI
Multiple forms of tubulin: different gene products and covalent modifications.
TL;DR: Although the significance of all the covalent modification of tubulin is not fully understood, some of them may influence the stability of modified microtubules in vivo as well as interactions with certain proteins and may help to determine the functional role of microtubule in the cell.

TL;DR: Several major shifts of taxonomic significance have been introduced at all levels treated, including the subphyla, and these revisions are explained in appropriately placed footnotes.

The ultrastructure and taxonomy of the Chrysophyceae and Prymnesiophyceae (Haptophyceae): a survey with some new observations on the ultrastructure of the Chrysophyceae
TL;DR: A model has been constructed which represents the combination of features constructed to be the basic pattern of cell structure in this group and it is suggested that this family should occupy a more isolated position in the Chrysophyceae than at present, possibly in a separate order Pedinellales.
Journal ArticleDOI
Revision of the Order Hypotrichida (Ciliophora, Protozoa)1
TL;DR: The revision recognizes 310 species distributed among 51 genera and 6 families, based on the known limits of structural variation as well as decisions relative to synonyms and homonyms.
