Available in PDF, EPUB and Kindle. Book excerpt: THIS BOOK HAS BEEN DEVELOPED FROM A SHORT LECTURE COURSE GIVEN to advanced undergraduate students as part of a general introduction to the subject of parasitology for zoologists. The book is written for the undergraduate who has no previous experience of parasitology and little background in either biochemistry or physiology. It is not a long book, and students will have to consult some of the more detailed textbooks in parasitology and physiology to gain a full understanding of the topics considered here. My objective in writing this book is to introduce the breadth of parasite physiology, leaving the reader to obtain a depth of knowledge by his own library research. Each chapter covers a single topic or related topics in physiological parasitology, and the variable length of the chapters reflects the amount of research interest that has been generated over the last few decades. It is to be hoped that by use of this book students will develop an interest in some of the more neglected areas and be stimulated to make good some of the more glaring deficiencies in our current knowledge. I should like to acknowledge with gratitude the assistance of my colleagues Dr 1. Barrett, Dr R. A. Klein, Dr A. W. Pike and Dr R. A.

Download or read book Ecology and Physiology of Parasites written by A. Murray Fallis and published by University of Toronto Press. This book was released on 1971-12-15 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing wisdom and ingenuity are required if we are to master our environment and cope with the myriad of organisms that affect our existence. Not the least of these organisms are the parasites and pathogens which can be found in all animals. The ecological implications of parasitism are obvious, and the interrelationships among different organisms within the same host are fascinating, but more knowledge and understanding are needed. The symposium are held to stimulate discussion of the significance of ecological problems presented by parasites and to develop means of attacking some of these problems. The diversity of parasitism from protozoa to anthropods was emphasized and the speakers and topics were selected to interest those in various biological disciplines and professions. Organized by the Department of Parasitology in the School of Hygiene of the University of Toronto, and held at Toronto in February 1970, the symposium was an unqualified success. The enthusiastic interest, indicated by the attendance of over three hundred people from seven countries, and numerous requests for copies of the proceedings led to the publication in this volume of the twelve papers presented at the symposium. The opening remarks of the leader of the discussion which follow each paper have been included and a complete bibliography is provided for each topic. The contributors are leading specialists in their fields; their papers present the results of the most recent research and assemble and review the scattered literature on each topic. The text is illustrated throughout with diagrams and photographs. Parasitism and associated phenomena are excellent examples of problems requiring the interdisciplinary approach taken by the symposium. The results of such an approach are useful in a wide variety of disciplines: microbiology, invertebrate zoology, entomology, and tropical medicine, as well as parasitology.

Available in PDF, EPUB and Kindle. Book excerpt: When Nancy Beckage and I first met in Lynn Riddiford's laboratory at the University of Washington in the mid 1970s, the fields of parasitology, behavior, and endocrinology were thriving and far-flung--disciplines in no serious danger of intersecting. There were rumors that they might have some common ground: Behavioural Aspects of Parasite Transmission (Canning and Wright, 1972) had just emerged, with exciting news not only of the way parasites themselves behave, but also of Machiavellian worms that caused intermediate hosts to shift fundamental responses to light and disturbance, becoming in the process more vulnerable to predation by the next host (Holmes and Bethel, 1972). Meanwhile, biologists such as Miriam Rothschild (see Dedication), G. B. Solomon (1969), and Lynn Riddiford herself (1975) had suggested that the endocrinological rami of parasitism might be subtle and pervasive. In general, however, para fications sites were viewed as aberrant organisms, perhaps good for a few just-so stories prior to turning our attention once again to real animals. In the decade that followed, Pauline Lawrence (1986a,b), Davy Jones (Jones et al. , 1986), Nancy Beckage (Beckage, 1985; Beckage and Templeton, 1986), and others, including many in this volume, left no doubt that the host-parasite combination in insect systems was physiologically distinct from its unparasitized counterpart in ways that went beyond gross pathology.

Download or read book Host Manipulations by Parasites and Viruses written by Heinz Mehlhorn and published by Springer. This book was released on 2015-11-09 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume focuses on parasite-host relationships and the behavioral changes parasites may trigger in their hosts. Parasites have developed strategies which enhance their chances to find a host to survive inside its body and to become most easily transmitted to one another. Many of these parasites influence the host’s behavior by various mechanisms, so that the rate of their transmissions to further hosts becomes considerably enhanced in comparison to that of non-influenced specimens of the same host species. A broad number of recent studies elucidate more and more examples in an extreme spectrum of host-parasite relationships, where successful transmission and /or survival of a parasite inside a host is based on parasite-derived behavioral manipulations of the hosts. In the literature, an increasing numbers of papers appear which prove that these behavioral alterations are based on complicated psychoimmunologic, neuropharmacologic and genomically steered mechanisms. Researchers working in parasitology or behavioral sciences will find this work thought-provoking, instructive and informative.

Download or read book Parasitic flowering plants written by Henning Heide-Jørgensen and published by BRILL. This book was released on 2008-07-31 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasitic flowering plants are strikingly impressive and beautiful and hold many surprises of both general and scientific interest. Parasites also have great influence on the quality of human life when attacking crop plants. Some parasites have since early times appealed to our imagination and have been part of religious or folkloristic events and used as gifts to royalties. This beautifully illustrated book covers all parasitic families and most of the genera. It also discusses the establishment of the parasite, the structure and function of the nutrient absorption organ (haustorium), and how the parasites are pollinated and dispersed as well as their ecology, hosts, and evolution. The book is written in a mostly non-technical language and is provided with a glossary and explanatory boxes. For additional information about this book, including some sample photographs, as well as a list of corrections that have been incorporated in the 2011 reprint, please visit the author's web site. Parasitic Flowering Plants was nominated by The Council on Botanical and Horticultural Libraries for the 2010 Annual Award for a Significant Work in Botanical or Horticular Literature, in the category ‘Technical Interest’.

Download or read book Parasite host Associations written by Catherine Ann Toft and published by Oxford University Press, USA. This book was released on 1991 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasitic relationships are among the most common yet complex associations found in nature. This book makes an important contribution toward integrating parasitology into the mainstream of ecological and evolutionary studies. It delves into a number of key questions: To what extent are parasite-host interactions an escalating evolutionary conflict and, conversely, to what extent has evolution modified this process to facilitate co-existence? The first section of the book deals with whole organisms and populations, since the effects of parasitism are dependent on the densities and distributions of hosts and parasites. The next section considers special cases, such as herbivores and plants. The third part is devoted to physiological and immunological aspects, and the book concludes with an overview from the perspectives of ecology, evolution, and physiology. The work will interest ecologists, evolutionary biologists, parasitologists, entomologists, and epidemiologists.

Download or read book Implications of Phenotype manipulating Parasites for Host Physiology and Behavior and a Study on Parasite Ecology written by Kelly Lynne Weinersmith and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasites impact the behavior of their hosts in three main ways post-infection: pathology, host-driven changes in behavior to reduce the cost of infection, and parasite-driven changes in host behavior to increase the likelihood of transmission (i.e., parasite manipulation of host behavior). For many years, parasite manipulation of host behavior has been treated as a fascinating, but rare, oddity. However, the list of parasites capable of manipulating host phenotype is growing. In many cases, manipulated hosts are abundant, and thus changes in their behavior are likely to be important for population and community ecology. The field of parasite manipulation of host phenotype has moved past mere cataloguing instances of manipulation and is now set to tackle more intellectually stimulating questions. Open questions include: 1) How does manipulation influence parasite and host ecology? 2) Through what mechanisms do parasites manipulate the phenotypes of their hosts? 3) How does manipulation influence the evolutionary trajectory of host behavioral traits? I address these questions using California killifish (Fundulus parvipinnis) and their brain-infecting trematode parasite, Euhaplorchis californiensis (EUHA). EUHA has a complex life cycle. As adults, the parasites live in the guts of predatory birds, where they mate and produce eggs that pass with the birds' feces into estuaries in southern California and Baja California. These eggs are consumed by California horn snails (Cerithidea californica), and the snails are subsequently castrated by the parasite. EUHA reproduces asexually in the snail, creating a free-swimming stage that is infective to California killifish. In killifish populations that co-occur with EUHA, nearly all adults are infected by the parasite, and often harbor over a thousand EUHA. The parasite appears to induce "conspicuous behaviors," such as quick jerks forward, that draw the attention of predatory birds and make the fish 10 to 30 times more likely to be consumed by these predators. Thus the parasite completes its life cycle. Previous work has observed that infection is associated with changes in baseline and stress-associated neurotransmitter activity, though the exact mechanisms through which EUHA induces conspicuous behaviors in the killifish remains unclear. In Chapter 1, I explore the ecology of EUHA. The density of parasite conspecifics infecting an intermediate host (such as California killifish) can have important implications for parasite fitness, as parasite volumes achieved in this host are often positively associated with egg production in adult parasites. Most studies examining density dependence in parasites residing in intermediate hosts have observed negative density dependence, but few studies have addressed questions of density dependence when parasites are small relative to their host (as is the case of EUHA infecting killifish). Here, we observed no signs of density dependence, and in fact observed that EUHA living at higher densities in naturally infected hosts exhibit larger individual volumes than EUHA experiencing less crowded conditions. This suggests that resources are not limited for EUHA in its killifish host, and in fact EUHA may benefit from the presence of conspecifics (e.g., through sharing the cost of immune system defense or the cost of manipulation). In Chapter 2, I validate a technique for non-invasive measurements of steroid hormones in naturally infected California killifish, and I look for correlations between hormone release rates and EUHA density. I found that the release of cortisol (a stress hormone) and 11-ketotestosterone (an androgen) across the killifish's gills during one hour of confinement in a beaker mirrors the concentrations of these hormones in the plasma. I also found that the interaction between handling stress and EUHA density was an important predictor of cortisol release rates, suggesting that EUHA manipulates the killifish stress response. This result could have important implications for killifish as they interact with predators. In Chapter 3, I consider how evolved dependence of hosts on their parasites may influence host behavior. When parasites are encountered every generation and are either impossible to avoid or too costly to eradicate post-encounter, hosts may adjust their physiology and behavior to compensate for the effects of infection. These changes in host phenotype may become fixed over long periods of time, and the sudden loss of parasites (e.g., due to lab breeding) would result in hosts whose phenotype are poorly matched to the environment. I draw on the evolved dependence and Hygiene Hypothesis literature and discuss how the loss of parasites may negatively impact host behavior, with implications for host fitness and evolution.
