This book provides an in-depth yet concise overview of the most common and emerging protozoa that cause diseases in both farm animals and companion animals. As outlined in the concise introduction, pathogenic protozoans represent an evolutionary highly diverse and little understood group of disease-causing microorganisms. For each of the featured parasitic unicellular eukaryotes, it discusses the morphology, lifecycle, epidemiology and host-pathogen interactions. In addition, the book highlights the latest developments in diagnostic methods, as well as prevention and treatment strategies. Thorough information on genomes and genetic manipulation strategies for some of the protozoa covered in this book is also included. Infections involving parasitic protozoa can cause productivity losses and/or reduce the quality of life of infected animals. Some infections are zoonotic, posing an on-going public health threat. In most cases, prevention and treatment are either non-existent or need considerable improvement. On the other hand, a great deal of research has recently been conducted on these organisms, yielding valuable new information on their global distribution and revealing the mechanisms of host-pathogen interactions at the molecular level – and essential insights that can be used for the development of new control tools. This book includes extensive information on both basic aspects and recent scientific discoveries on these protozoa and thus constitutes a unique resource for students, veterinarians, and researchers alike.

The book “Parasitic Zoonoses” emphasizes a veterinary and public health perspective of zoonotic parasites. This book is suitable for higher undergraduate and graduate students of zoonoses and public health, veterinary parasitology, parasite epidemiology; public health workers; public health veterinarians; field veterinarians, medical professionals and all others interested in the subject. More than 15 protozoa and 50 other parasitic diseases are zoonotic in nature and all these diseases have been discussed in detail. The first chapter is concerned with classification of zoonotic parasites, food borne, vector borne and occupation related zoonotic parasites. The remaining chapters cover etiology, epidemiology, life cycle, transmission, clinical signs, diagnosis, prevention and control of zoonotic parasites. The text is illustrated with a large number of coloured figures. An alphabetical bibliography for every disease has also been included so that readers have access to further information.

The manual is intended as a tool for the identification and control of the wide spectrum of parasites affecting domestic animals throughout the world. It's of great value for personnel in field laboratories, veterinarians and technicians, as well as for teachers and students. On another practical level, it is relevant for meat inspectors and other public health officials to identify parasites in domestic animals which are potentially harmful to humans.

Why does the World Health Organization (WHO) put emphasis on neglected tropical diseases (NTDs)? What are the NTDs? Are NTDs found in the United States? Is there any relationship between coronavirus disease 2019 (COVID-19) and NTDs? These are some of the questions being addressed in the book.The aim of this textbook is to introduce a modern synthesis on human parasites of medical importance. Species of parasitic protozoa and helminths are presented in detail, from history and discovery to aspects of genomes and molecular biology, together with life cycle, therapy, drug resistance, and case studies of parasitic diseases useful to the clinicians.

This textbook focuses on the most important parasites affecting dogs, cats, ruminants, horses, pigs, rabbits, rodents, birds, fishes, reptiles and bees. For each parasite, the book offers a concise summary including its distribution, epidemiology, lifecycle, morphology, clinical manifestations, diagnosis, prophylaxis and therapeutic measures. Numerous informative tables and more than 500 color micrographs and schemes present the most important aspects of the parasites, their induced diseases and the latest information on suitable prevention and control measures. 100 questions at the end of the book offer readers the chance to test their comprehension. The book is well suited as both a textbook and a reference guide for veterinarians, students of the veterinary and life sciences, veterinarian nurses, laboratory staff, and pet and livestock owners.

Lack of clean water, inadequate sanitation, and insufficient infection prevention and control promote the spread of parasites. The discovery of antiparasitic drugs was considered a milestone in the veterinary and medical sciences, but their use has subsequently become limited due to the emergence of resistance. While plenty of attention has been given in human and animal health communities to the global threat of antimicrobial drug resistance, specific antiparasitic advice is less available. This book provides an in-depth view of the issue for parasitologists, pharmacologists and veterinary scientists. Specifically discussing antiparasitic drug resistance mechanisms and factors responsible for the problem.

This issue of Veterinary Clinics: Food Animal Practice, guest edited by Dr. Ray M. Kaplan, focuses on Ruminant Parasitology. This is one of three issues each year selected by the series consulting editor, Dr. Robert A. Smith. Articles in this issue include, but are not limited to: biology and epidemiology of GI nematode parasites in cattle, epidemiology and control of GI parasites of cattle in southern climates, epidemiology and control of GI parasites of cattle in northern climates, anthelmintic resistance and strategies for sustainable control of parasites, refugia-based strategies for parasite control in livestock, epidemiology and control of liver flukes, diagnostic methods in livestock parasitology, parasite vaccines, what Modeling parasites, transmission and resistance can teach us, fecal egg count reduction tests in cattle and small ruminants, ectoparasites of ruminants, ruminant coccidiosis, neosporosis, toxoplasmosis, and sacocystosis in ruminants, girdiasis and cryptosporidiois in ruminants, biology, epidemiology and control of GI nematodes in small ruminants, and realistic approaches to parasite control in ruminant livestock.
