Available in PDF, EPUB and Kindle. Book excerpt: Roundworms are the most prevalent parasite of swine in the world today. Their presence on a pig farm can have detrimental effects on farm profitability due to their impact on growth rate, feed conversion, and general health of the produced pigs. For farmers, it is therefore essential to be aware of the “worm status” of their herd in order to make informed decisions on how to control this disease on their farm. This chapter concentrates on the diverse aspects involved in the diagnosis and control of Ascaris suum infections on pig farms. It focuses on how the results obtained from different detection methods should be interpreted and what efforts could be made to control parasite transmission and consequentially reduce the prevalence and economic impact of this parasite on a pig farm.

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: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Larval ascariasis is much less well understood than adult worm infection. Part of the explanation for this is the difficulty in assessing the impact of larval infections in human subjects. In contrast, adult worms can be counted after post-chemotherapeutic expulsion or, additionally, eggs voided in host feces can be quantified as an indirect measure of infection intensity. Furthermore, respiratory and hepatic disease, which may be associated with transient passage of larvae through these organs, can be either non-specific or cryptic, making Ascaris-specific diagnosis through clinical signs of infection challenging. The influence of early infection on parasite establishment and host immunity is recognized as important but it remains challenging to unravel the complexities of the relationship. Both pigs as natural hosts of Ascaris suum and a range of abnormal hosts have been utilized to investigate larval migration. Few if any of these model systems have enabled clarification of the basis of variation in susceptibility and resistance to larval migration and accumulation in the liver and lungs. In this chapter, we document the literature on larval ascariasis with a particular emphasis on studies utilizing mice because mice are now developing as useful model systems for the study of early Ascaris infection, the migratory path and its duration being similar to that of pigs. We describe a mouse model of early Ascaris infection that mimics the extremes of the host phenotype displayed in the aggregated distribution of adult worms in human and pig populations, outline the existing evidence for the role of the liver in susceptibility to larval ascariasis and discuss future directions for the use of this model system.

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.

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.
