Parasites, Pussycats and Psychosis


Book Description

This open access book analyzes the evidence linking Toxoplasma gondii to the increasing incidence of schizophrenia and bipolar disorder in the United States. Initially establishing that infectious agents are regularly transmitted from animals to humans, lead to human disease, and that infectious agents can cause psychosis, it then examines the protozoan parasite Toxoplasma gondii in detail. Infecting 40 million Americans, Toxoplasma gondii is known to cause congenital infections, eye disease, and encephalitis for individuals who are immunosuppressed. It has also been shown to change the behavior of nonhuman mammals, as well as to alter some personality traits in humans. After discussing the clinical evidence linking Toxoplasma gondii to human psychosis, the book elucidates the epidemiological evidence further supporting this linkage; including the proportional increase in incidence of human psychosis as cats transitioned to domestication over 800 years. Finally, the book assesses the magnitude of the problem and suggests solutions. Parasites, Pussycats and Psychosis: The Unknown Dangers of Human Toxoplasmosis provides a comprehensive review of the evidence linking human psychosis in the United States to infections of Toxoplasma gondii. It will be of interest to infectious disease specialists, general practitioners, scientists, historians, and cat-lovers.




Toxoplasmosis of Animals and Humans


Book Description

Found worldwide from Alaska to Australasia, Toxoplasma gondii knows no geographic boundaries. The protozoan is the source of one of the most common parasitic infections in humans, livestock, companion animals, and wildlife, and has gained notoriety with its inclusion on the list of potential bioterrorism microbes. In the two decades since the publi




Toxoplasmosis, Cats, Humans, and Nature


Book Description

All cat owners should have at least some basic knowledge about cat toxoplasmosis; a cat zoonosis also referred to as cat litter disease. The protozoan parasite that causes the disease, Toxoplasma Gondii, is a public health issue. It is also an economic and environmental issue. The decisions and behavior of cat owners, with respect to cat care and feeding, cat litter cleaning, and cat litter disposal, can have a positive or negative impact in these respects. Claude Bois studied scientific literature and reviewed the recommendations of health authorities about this widespread cat litter disease. It is important to understand the risk associated with cleaning cat litter, even more so if cleaning cat litter while pregnant. Hence, the book gives lots of information to evaluate whether a cat is contagious or not. You will find practical solutions for safe litter cleaning during contagious periods. You will also learn proper cat litter disposal for environmental conservation. The information is summarized down in a way that is accessible and enables readers to make enlightened decisions about such an important cat litter disease. A word from the author Claude Bois After writing four books on cat litters, cat cleanliness, and cat training, I noticed some false information is circulating about toxoplasmosis and what should or should not be done with cats’ litter and poops. Considering the risk associated with this serious cat litter disease, I was very concerned about doing the right thing for environmental conservation and human health. Hence, I thoroughly investigated this subject. Then I wrote Toxoplasmosis, Cats, Humans, and Nature. ** For more details and discover other books in this collection, visit PetFriendsFreedom.com > pets > cats > cleanliness.

Book Description

Complete information on T. gondii infections in animals and man is summarized and analyzed in this thorough reference text. Critical in-formation on its economic impact and its effect on production of animals whose flesh is used for food is featured. The clinical and subclinical infections in all major species of livestock are pre-sented. For each animal species, worldwide serological prevalences are tabulated with T. gondii antibody titers, followed by an experi-mental section. Worldwide prevalences of T. gondii infections in mankind is summarized, highlighting epidemiology, symptom diag-nosis, treatment, and prevention. Past research is summarized and areas of future investigations are suggested. This book is highly useful to veterinarians, physicians, biologists, and researchers.




Cat Wars


Book Description

Why our cats are a danger to species diversity and human health In 1894, a lighthouse keeper named David Lyall arrived on Stephens Island off New Zealand with a cat named Tibbles. In just over a year, the Stephens Island Wren, a rare bird endemic to the island, was rendered extinct. Mounting scientific evidence confirms what many conservationists have suspected for some time—that in the United States alone, free-ranging cats are killing birds and other animals by the billions. Equally alarming are the little-known but potentially devastating public health consequences of rabies and parasitic Toxoplasma passing from cats to humans at rising rates. Cat Wars tells the story of the threats free-ranging cats pose to biodiversity and public health throughout the world, and sheds new light on the controversies surrounding the management of the explosion of these cat populations. This compelling book traces the historical and cultural ties between humans and cats from early domestication to the current boom in pet ownership, along the way accessibly explaining the science of extinction, population modeling, and feline diseases. It charts the developments that have led to our present impasse—from Stan Temple's breakthrough studies on cat predation in Wisconsin to cat-eradication programs underway in Australia today. It describes how a small but vocal minority of cat advocates has campaigned successfully for no action in much the same way that special interest groups have stymied attempts to curtail smoking and climate change. Cat Wars paints a revealing picture of a complex global problem—and proposes solutions that foresee a time when wildlife and humans are no longer vulnerable to the impacts of free-ranging cats.




Toxoplasma gondii


Book Description

For years, toxoplasmosis has been known as disease mostly affecting newborns. Since immunocompromised patients (AIDS) present a high risk of reactivation of chronic toxoplasmosis this parasitic disease has gained increasing interest. Besides presenting clinical and therapeutical concepts, this volume provides current knowledge about genetics and immunology of T. gondii and the interaction with its 'host'. Since in vivo and in vitro models of toxoplasmosis exist, and genetic manipulation has become possible, this protozoan parasite has recently been accepted as a model for understanding the pathogenesis and persistance of other intracellular parasites. The articles of the book compromise both reviewing current concepts and reporting on yet unpublished results of leading scientists in this field.




Toxoplasma Gondii


Book Description

This 2e of Toxoplasma gondii reflects the significant advances in the field in the last 5 years, including new information on the genomics, epigenomics and proteomics of T. gondii as well as a new understanding of the population biology and genetic diversity of this organism. T. gondii remains the best model system for studying the entire Apicomplexa group of protozoans, which includes Malaria, making this new edition essential for a broad group of researchers and scientists. Toxoplasmosis is caused by a one-celled protozoan parasite known as T. gondii. The infection produces a wide range of clinical syndromes in humans, land and sea mammals, and various bird species. Most humans contract toxoplasmosis by eating contaminated, raw or undercooked meat (particularly pork), vegetables, or milk products; by coming into contact with the T. gondii eggs from cat feces; or by drinking contaminated water. The parasite damages the ocular and central nervous systems, causing behavioral and personality alterations as well as fatal necrotizing encephalitis. It is especially dangerous for the fetus of an infected pregnant woman and for individuals with compromised immune systems, such as HIV-infected patients. - Completely updated, the 2e presents recent advances driven by new information on the genetics and genomics of the pathogen - Provides the latest information concerning the epidemiology, diagnosis, treatment and prevention of toxoplasmosis - Offers a single-source reference for a wide range of scientists and physicians working with this pathogen, including parasitologists, cell and molecular biologists, veterinarians, neuroscientists, physicians, and food scientists




Host Manipulation by Parasites


Book Description

The Neurobiological Basis of Suicide


Book Description

With recent studies using genetic, epigenetic, and other molecular and neurochemical approaches, a new era has begun in understanding pathophysiology of suicide. Emerging evidence suggests that neurobiological factors are not only critical in providing potential risk factors but also provide a promising approach to develop more effective treatment and prevention strategies. The Neurobiological Basis of Suicide discusses the most recent findings in suicide neurobiology. Psychological, psychosocial, and cultural factors are important in determining the risk factors for suicide; however, they offer weak prediction and can be of little clinical use. Interestingly, cognitive characteristics are different among depressed suicidal and depressed nonsuicidal subjects, and could be involved in the development of suicidal behavior. The characterization of the neurobiological basis of suicide is in delineating the risk factors associated with suicide. The Neurobiological Basis of Suicide focuses on how and why these neurobiological factors are crucial in the pathogenic mechanisms of suicidal behavior and how these findings can be transformed into potential therapeutic applications.




This Is Your Brain On Parasites


Book Description

“Engrossing . . . [An] expedition through the hidden and sometimes horrifying microbial domain.” —The Wall Street Journal Parasites can live only inside another animal and, as Kathleen McAuliffe reveals, these tiny organisms have many evolutionary motives for manipulating the behavior of their hosts. With astonishing precision, parasites can coax rats to approach cats, spiders to transform the patterns of their webs, and fish to draw the attention of birds that then swoop down to feast on them. We humans are hardly immune to their influence. Organisms we pick up from our own pets are strongly suspected of changing our personality traits and contributing to recklessness and impulsivity—even suicide. Germs that cause colds and the flu may alter our behavior even before symptoms become apparent. Parasites influence our species on the cultural level, too. Drawing on a huge body of research, McAuliffe argues that our dread of contamination is an evolved defense against parasites. The horror and revulsion we are programmed to feel when we come in contact with people who appear diseased or dirty helped pave the way for civilization, but may also be the basis for major divisions in societies that persist to this day. This Is Your Brain on Parasites is both a journey into cutting-edge science and a revelatory examination of what it means to be human. “If you’ve ever doubted the power of microbes to shape society and offer us a grander view of life, read on and find yourself duly impressed.” —Bookforum “Fascinating—and full of the kind of factoids you can’t wait to share.” —Scientific American “Humorous, inspiring, and macabre, this is infectious reading in the tradition of giants like Robert S. Desowitz and Jared Diamond.” —Michael A. Huffman, Primate Research Institute, Kyoto University
