Book Description
Parasite control is an important aspect of health management of horses, particularly the control of gastrointestinal (GI) parasites. Recently, treatment recommendations have involved selective use of anthelmintics in horses with fecal egg counts (FEC) greater than a specified threshold. The objectives of this study were; (1) to determine the prevalence of helminths in our area by egg and L3 determinations, (2) to determine if certain horses maintained low FEC, therefore eliminating the need to treat them on a year-round basis and (3) to determine the effectiveness of four common treatments (moxidectin, ivermectin (pioneer and generic), fenbendazole and pyrantel tartrate) via a standardized fecal egg count reduction (FECR) test. Fecal samples were collected from 226 horses at 14 different farms with a total of 933 fecal samples and 259 coprocultures evaluated over eight months. A treatment threshold of FEC > 200 eggs per gram (EPG) was used and horses were sampled once, twice, or three times over the course of the study. Of the 933 fecals analyzed, 303 had an EPG of zero, 407 were 200 EPG. There were 37 samples that contained eggs other than Strongyle-type eggs and at least one of the three major large strongyle species were found in seven of 259 coprocultures evaluated. During the study, 125 horses were treated and 101 horses did not require treatment. Of these, six of the horses were sampled three times without exceeding the treatment threshold. The efficacy of both moxidectin and ivermectin was high (98.5% and 99.7% FECR), fenbendazole was expectedly low (57.7% FECR), and the efficacy of pyrantel was difficult to elucidate since all treatments were preceded by moxidectin. These results are consistent with other published studies that suggest using selective treatment to control equine GI parasites.

Book Description
Zoonotic diseases represent one of the leading causes of illness and death from infectious disease. Defined by the World Health Organization, zoonoses are "those diseases and infections that are naturally transmitted between vertebrate animals and man with or without an arthropod intermediate." Worldwide, zoonotic diseases have a negative impact on commerce, travel, and economies. In most developing countries, zoonotic diseases are among those diseases that contribute significantly to an already overly burdened public health system. In industrialized nations, zoonotic diseases are of particular concern for at-risk groups such as the elderly, children, childbearing women, and immunocompromised individuals. The Emergence of Zoonotic Diseases: Understanding the Impact on Animal and Human Health, covers a range of topics, which include: an evaluation of the relative importance of zoonotic diseases against the overall backdrop of emerging infections; research findings related to the current state of our understanding of zoonotic diseases; surveillance and response strategies to detect, prevent, and mitigate the impact of zoonotic diseases on human health; and information about ongoing programs and actions being taken to identify the most important needs in this vital area.

Book Description
Globalization of the food supply has created conditions favorable for the emergence, reemergence, and spread of food-borne pathogens-compounding the challenge of anticipating, detecting, and effectively responding to food-borne threats to health. In the United States, food-borne agents affect 1 out of 6 individuals and cause approximately 48 million illnesses, 128,000 hospitalizations, and 3,000 deaths each year. This figure likely represents just the tip of the iceberg, because it fails to account for the broad array of food-borne illnesses or for their wide-ranging repercussions for consumers, government, and the food industry-both domestically and internationally. A One Health approach to food safety may hold the promise of harnessing and integrating the expertise and resources from across the spectrum of multiple health domains including the human and veterinary medical and plant pathology communities with those of the wildlife and aquatic health and ecology communities. The IOM's Forum on Microbial Threats hosted a public workshop on December 13 and 14, 2011 that examined issues critical to the protection of the nation's food supply. The workshop explored existing knowledge and unanswered questions on the nature and extent of food-borne threats to health. Participants discussed the globalization of the U.S. food supply and the burden of illness associated with foodborne threats to health; considered the spectrum of food-borne threats as well as illustrative case studies; reviewed existing research, policies, and practices to prevent and mitigate foodborne threats; and, identified opportunities to reduce future threats to the nation's food supply through the use of a "One Health" approach to food safety. Improving Food Safety Through a One Health Approach: Workshop Summary covers the events of the workshop and explains the recommendations for future related workshops.

Book Description
Medical and Veterinary Entomology, Second Edition, has been fully updated and revised to provide the latest information on developments in entomology relating to public health and veterinary importance. Each chapter is structured with the student in mind, organized by the major headings of Taxonomy, Morphology, Life History, Behavior and Ecology, Public Health and Veterinary Importance, and Prevention and Control. This second edition includes separate chapters devoted to each of the taxonomic groups of insects and arachnids of medical or veterinary concern, including spiders, scorpions, mites, and ticks. Internationally recognized editors Mullen and Durden include extensive coverage of both medical and veterinary entomological importance. This book is designed for teaching and research faculty in medical and veterinary schools that provide a course in vector borne diseases and medical entomology; parasitologists, entomologists, and government scientists responsible for oversight and monitoring of insect vector borne diseases; and medical and veterinary school libraries and libraries at institutions with strong programs in entomology.

Book Description
Large Animal Parasitology Procedures for Veterinary Technicians Comprehensive illustrated reference on parasitic nematodes, cestodes, coccidian oocysts and trematode egg recoveries, identification, and enumeration with treatment strategies for five separate categories of animal patients Large Animal Parasitology Procedures for Veterinary Technicians illustrates, in detail, the most sensitive diagnostic procedure for internal parasites of domestic animals using the Modified Wisconsin Sugar Flotation Method. With step-by-step pictures and bullet-point instructions, this text discusses sample collection and storage techniques, as well as the strengths and weaknesses inherent to other commonly used tests. Potential sources for infection, the seasonality of the infection, possible environmental recontamination, and control strategies are all covered in detail, with suggestions to prevent reoccurrences. Parasites of the equine, large and small ruminants (including alpaca), swine, poultry and hoofed wildlife patients are included, with full color images for quick identification, an assessment of life cycle stage, and discussion of zoonotic potential. Each species section is heavily illustrated with comparative images to aid the technician in quickly identifying the parasite and life cycle stage. In Large Animal Parasitology Procedures for Veterinary Technicians, readers can find information on: The definition and economic importance of parasitisms, details on the epidemiology of parasitic enteritis, including basics of protozoology, helminthology, and overall applied veterinary parasitology Sample collection and shipment of specimens, including collection, storage, examinations, and interpretations Fecal examination using the Modified Wisconsin Sugar Flotation method, compared with gross examination, smear, sedimentation, and other flotation techniques, plus a fluke egg recovery technique and the Baermann technique for lungworm larvae recovery Internal parasite diagnosis and worm egg recoveries, descriptions and pictures of nematode parasite eggs (as well as coccidia oocysts), plus tapeworm eggs and fluke egg descriptions and photos for a variety of host animals Illustrating commonly used diagnostic tests in veterinary parasitology, with step-by-step instructions for accuracy, Large Animal Parasitology Procedures for Veterinary Technicians is an essential reference for veterinary technicians and veterinary technician students dealing with domestic animals, including horses, ruminants, swine, poultry, and hoofed wildlife.
