Book excerpt: This book tackles a number of different perspectives concerning the parasitic helminth Ascaris, both in animals and in humans and the disease known as ascariasis. It seeks to identify interesting, exciting and novel aspects, which will interest readers from a broad range of disciplines.Over a quarter of the world's population are infected with the human roundworm, and the equivalent in pigs is equally ubiquitous. Both contribute to insidious and chronic nutritional morbidity, and this has been quantified, in humans, as disability adjusted life years approximating 10.5 million. Ascaris larvae develop in host parenteral tissues, and the resultant pathology has been condemnation. Ascariasis, despite its staggering global prevalence and the sheer numbers of people it infects, remains a classic neglected disease. However, renewed interest in the consequences of early infection with worms from the perspective of immune modulation, co-infections and the development of allergy further enhances the relevance of these parasites. Brings together a wide range of topics and approaches and recent, comprehensive and progressive research concerning the neglected parasite Ascaris Provides a blueprint of how a single parasite entity can stimulate interest in basic biology, clinical science, veterinary science, public health and epidemiology Presents a wealth of new insights given that a book on this parasite has not been published for over 20 years 16 chapters from a range of top authors from around the world

Available in PDF, EPUB and Kindle. Book excerpt: The roundworm Ascaris suum is a highly prevalent intestinal parasite of pigs worldwide, and the infection may have low to moderate pathogenic effects on health and productivity. Besides these direct effects, there may be indirect effects on enhanced susceptibility or pathogenicity to bacterial or viral infections, related to the migratory and immune-modulatory capacity of A. suum. Losses due to ascariasis in pigs can thus be summarized as (1) farm economic losses due to clinical effects (although limited), reduced growth and feed conversion efficiency and costs of control (e.g. use of anthelmintics), (2) abattoir operator losses due to condemnation or downgrading of livers and lower product quality, and (3) potential interference with vaccinations and higher risk of co-infections. Apart from the cost of liver condemnations that can be extrapolated from available data, it is difficult to quantify losses.
Download or read book The Geohelminths written by Celia V. Holland and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: The soil-transmitted nematode parasites, or geohelminths, are - called because they have a direct life cycle, which involves no intermediate hosts or vectors, and are transmitted by faecal contamination of soil, foodstuffs and water supplies. They all inhabit the intestine in their adult stages but most species also have tissue-migratoryjuvenile stages, so the disease manifestations they cause can therefore be both local and systemic. The geohelminths together present an enormous infection burden on humanity. Those which cause the most disease in humans are divided into three main groupings, Ascaris lumbricoides (the large roundworm), Trichuris trichiura (whipworm), and the blood-feeding hookworms (Ancylostoma duodenale and Necator americanus ), and this book concentrates on these. These intestinal parasites are highly prevalent worldwide, A. lumbricoides is estimated to infect 1471 million (over a quarter ofthe world’s population), hookworms 1277 million, and T. trichiura 1049 million. The highly pathogenic Strongyloides species might also be classified as geohelminths, but they are not dealt with here because the understanding of their epidemiology, immunology and genetics has not advanced as rapidly as for the others. This is primarily because of the often covert nature of the infections, with consequent difficulties for analysis. If there is ever a second edition of this book, then there will hopefully be much to say about this infection.

Book excerpt: When Professor John Sprent first suggested, in 1982, that the Australian Society for Parasitology should bid for the opportunity to mount the Sixth International Congress of Parasitology, the immediate reaction was one of disbelief. However, in the two years or so before ICOPA 5, in Toronto, he used his considerable powers to the utmost and spent himself unstintingly in persuading Australian parasitologists to put together a bid. The Society inevitably agreed, for it is difficult to prevent such a determined and eminent man from getting his own way! A case for an Australian venue was prepared and, as President, I was charged with the task of convincing the delegates in Toronto that Australia was worth going all the way to see. The events of that meeting are now far in the past; suffice to say that, in the end, Australia won by the narrowest of margins, largely due to the energy of my inventive colleagues who put the case for Australia at every possible and improbable moment. I do not remember a great deal about the scientific aspects of ICOPA 5. I was far too preoccupied with an awful spectre, that of telling John Sprent that I had failed, to pay attention to much other than lobbying for votes. I do remember, however, telling myself how much I would enjoy the next ICOPA without the terrible responsibility of capturing ICOPA 7.

Book excerpt: This very well-received book, now in its second edition, equips the radiologist with the information needed in order to diagnose internal medicine disorders and their complications from the radiological perspective. It offers an easy-to-consult tool that documents the most common and most important radiological signs of a wide range of diseases, across diverse specialties, with the aid of an excellent gallery of images and illustrations. Compared with the first edition, numerous additions and updates have been made, with coverage of additional disorders and inclusion of many new images. Entirely new chapters focus on occupational medicine and toxicology imaging, chiropractic medicine, and energy and quantum medicine. Internal Medicine – An Illustrated Radiological Guide puts the radiologist in the internal medicine physician’s shoes. It teaches radiologists how to think in terms of disease progression and complications, explains where to look for and to image these complications, and identifies the best modalities for reaching a diagnosis. It will also benefit internal medicine physicians by clarifying the help that radiology can offer them and assisting in the choice of investigation for diagnostic confirmation.
Download or read book Ascaris The Neglected Parasite written by Aaron R. Jex and published by Elsevier Inc. Chapters. This book was released on 2013-05-09 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasitic nematodes cause substantial morbidity and mortality in animals and people globally and major losses to food production annually. Ascaris is among the commonest geohelminths of swine and people worldwide, and causes major disease and socioeconomic losses, particularly in developing countries. The control of ascariasis has become a global health and welfare priority, but current treatment programs carry a significant risk of inducing anthelmintic resistance. Therefore, there is a need to work toward the sustainable control of Ascaris/ascariasis, built on a solid understanding of its molecular biology and genetics. Recently, we reported the 273 megabase (Mb) draft genome of Ascaris suum (sequenced from the reproductive tract of a single adult female worm) and explored transcription in different organs, stages, and both sexes of this nematode using advanced sequencing and computer technologies. We characterized key genes and biological pathways linked to the parasite’s migration in the host, and its immunobiology, reproduction, and development. We also predicted and prioritized drug targets in A. suum, providing a basis for discovering new groups of nematocides. The present chapter provides an account of these recent advances, describes new methodologies established, and emphasizes prospects for profound investigations into the comparative genomics, genetics, evolution, immunobiology, epidemiology, and ecology of Ascaris from both pig and human hosts as well as for the development of new interventions against ascariasis and other helminthiases.

Available in PDF, EPUB and Kindle. Book excerpt: To better understand the epidemiology of ascariasis, molecular genetic methods have been applied to differentiate between worms found infecting people and pigs, and other occasional hosts. Owing to difficulties in applying species concepts, the longstanding debate of the distinction(s) between Ascaris lumbricoides and Ascaris suum continues. From an applied perspective, however, molecular markers help to “tag” and “track” worms during their transmission cycle(s), providing new insights into host range, as well as methods for assessing parasite population dynamics through time and contingent upon disease control. While useful in determining dynamics at the tips of the evolutionary tree, these molecular tools also provide insights into deeper evolutionary branches. Although Ascaris is found throughout the globe, molecular analysis of worms retrieved from sub-Saharan Africa point towards a significant center of genetic diversity, possibly denoting a likely center of evolutionary origin with subsequent parasite diaspora. Resolving these issues precisely, however, requires greater scrutiny of genetic variation within Parascaris and Baylisascaris.

Download or read book Ascaris The Neglected Parasite written by Philip J. Cooper and published by Elsevier Inc. Chapters. This book was released on 2013-05-09 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural infections with Ascaris lumbricoides and A. suum of pigs and humans, respectively, have a worldwide distribution. Ascaris infections induce strong Th2 responses in the host that appear to be central to the development of protective immunity. Th2 responses may be modulated actively through a complex host–parasite interaction that allows the parasite to survive but also limits severe Th2-mediated pathology in the host. The increased production of IL-10 by regulatory cell populations may have a key role in the modulation of the immune response during chronic ascariasis although most evidence in support is derived from experimental infections with A. suum and A. suum antigen extracts. Antigen fractions of A. suum have potent anti-inflammatory effects in experimental models of arthritis and asthma, but other antigen fractions are strong inducers of inflammation. The clinical effects of such immune modulation in humans is uncertain although there is some evidence that chronic infections may be associated with impaired immune responses to vaccines indicating potentially important effects on both mucosal and systemic immunity. Human ascariasis has been associated with an increased risk of asthma and other allergic reactions, observations that preclude the use of experimental infections for the treatment of inflammation in favor of the study of the anti-inflammatory properties of specific molecules derived from Ascaris.
