This book then studies the protozoan superclass Rhizopoda, subphylum Actinopoda, slime molds, and subphylum Sporozoa, as well as toxoplasma. Phytoflagellates, zooflagellates, and ciliates are also tackled. This book concludes by explaining membrane differentiations, fibrous structures, and relationships of protozoa. This publication will be invaluable to biologists and other scientists interested in studying protozoa.
Download or read book Fine Structure of Parasitic Protozoa written by E. Scholtyseck and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: The plan for this atlas evolved from the necessity of providing the biology student interested in protozoology, cytology, and para sitology with an introduction to the study of fine structure in Protozoa. To reduce the book's extend, a selection of characteristic protozoans had to be made, limited to those which could be regarded as representative for entire groups. Interest in parasitic protozoans has been steadily on the increase over the last 10 years. This particular group of organisms thus seemed a very suitable choice. The" Apicomplexa" were selected as an area of emphasis. These once were part of the collective group called Sporozoa which included many parasitic protozoans of uncertain taxonomy. Fine structural research has been of especial significance for the Apicomplexa, since Protozoa belonging to this subgroup can now be named, characterized, and classified by features recognizable by electron microscopy. Only the fine structure of whole cells is represented in this atlas, so that the ciliates have been of necessity excluded. Their cells are too large in diameter in any case for our purpose here. They also play only a minor role as parasitic organisms. This book utilizes a new method to facilitate the analysis of protozoan fine structure. An electron micrograph, a descriptive text, and an analytic drawing are arranged on two facing pages so that the electron micrograph and the drawing can be compared.
Download or read book Ecology of Protozoa written by Genoveva F. Esteban and published by Springer Nature. This book was released on 2021-01-04 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book emphasises the important role that protozoa play in many natural ecosystems. To shed new light on their individual adaptive skills, the respective chapters examine the ecology and functional biology of this diverse group of eukaryotic microbes. Protozoa are well-established model organisms that exemplify many general problems in population ecology and community ecology, as well as evolutionary biology. Their particular characteristics, like large population sizes, life cycles and motile sensory behaviour, have a profound impact on their survival, distribution, and interaction with other species. Thus, readers will also be introduced to protozoan habitats in a broad range of environments. Even though this group of unicellular organisms is highly diverse, the authors focus on shared ecological patterns. Students and scientists working in the areas of eukaryotic microbiology and ecology will appreciate this updated and revised 2nd Edition as a valuable reference guide to the “lifestyles” of protozoa.

Download or read book Electron Microscopy of Plant Pathogens written by Kurt Mendgen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants, fungi, and viruses were among the first biological objects studied with an electron microscope. One of the two first instruments built by Siemens was used by Helmut Ruska, a brother of Ernst Ruska, the pioneer in constructing electron microscopes. H. Ruska published numerous papers on different biological objects in 1939. In one of these, the pictures by G. A. Kausche, E. Pfankuch, and H. Ruska of tobacco mosaic virus opened a new age in microscopy. The main problem was then as it still is today, to obtain an appropriate preparation of the specimen for observation in the electron microscope. Beam damage and specimen thickness were the first obstacles to be met. L. Marton in Brussels not only built his own instrument, but also made considerable progress in specimen preparation by introducing the impregnation of samples with heavy metals to obtain useful contrast. His pictures of the bird nest orchid root impregnated with osmium were revolutionary when published in 1934. It is not the place here to recall the different techniques which were developed in the subsequent years to attain the modern knowledge on the fine structure of plant cells and of different plant pathogens. The tremendous progress obtained with tobacco mosaic virus is reflected in the chapter by M. Wurtz on the fine structure of viruses in this Volume. New cytochemical and immunological techniques considerably surpass the morphological information obtained from the pathogens, especially at the host-parasite interface.

Download or read book Giardia and Giardiasis written by Stanley L. Erlandsen and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intestinal protozoan Giardia was first described over 300 years ago in 1681 by Leeuwenhoek, from his own stools. In his description of Giardia, he noted the size, movement, and morphology of the organism, and associated its presence with the diarrheic nature of his stools and his dietary habits. This truly remarkable account contains the first description of Giardia in morphologic, pathogenic, and epidemiologic terms. Our knowledge of the organisms in the genus Giardia has advanced tremendously in the past two decades. With the advent of new tech nologies, including techniques in electron microscopy, biochemistry, immunochemistry, tissue culture, and physiology, a tidal wave of information has appeared on the organization and function of this parasitic protozoan and its interaction with its host. The purpose of this book is to celebrate the tricentennial discovery of Giardia by Leeuwenhoek by presenting the above-mentioned advances in our knowledge of Giardia and giardiasis. In the first section of this book, the dominant theme is the biology of the organism and the correlation of structure-function relationships.

Download or read book Nutrition and Feeding Strategies in Protozoa written by Brenda Nisbet and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: 1 Modern biologists describe protozoa as microscopic eukaryotic organ isms with a capacity for establishing themselves in almost every con ceivable habitat provided it contains moisture in some form. In 1674 at the time when Antony von Leeuwenhoek was making his first observations of 'very small animalcules' in Berkelse Mere near his home town of Delft, this concept of the ubiquity of protozoa would have been difficult to comprehend. Leeuwenhoek's curiosity later led him to examine the body fluids, gut contents and excreta of different animals and to describe 'an inconceivably great company of living animalcules, and these of divers sorts and sizes'. Here were early des criptions of parasitic protozoa, species which later came to be recog nized as Opalina, Giardia, Trichomonas and others. Following his pioneering work in the field of microscopic observation, knowledge of protozoa has accumulated at an accelerating pace. Some 30,000 living species have been identified, and an equal number of fossil species, from habitats which range from the ocean waters to the exuvial fluid of insects. The study of protozoan nutrition is a particularly interesting aspect of this expanding field of zoology. What kind of nourishment do protozoa need, how do they acqlire it, and what influence do the answers to these two questions havE on where protozoa live? The need to determine what hId of food protozoa are utilizing in their environment is desirable in al ecological studies involving micro organisms of aquatic communities.
