Preface

Parasitic infections, a major global concern, adversely affect cattle health as well as production by losing the economic status of the farmers significantly in terms of declined milk production, inferior meat quality, depreciation of hide, loss of manure production, and draught power. A significant pinpoint evaluation of diseases as well as confirmatory diagnosis is required for specific treatment of both ecto- and endo-parasites. In addition, morphological identification of parasites is a basic important tool for the standard methods for diagnosis. Histopathological analysis of parasitic diseases may play an important role in the diagnosis as well as in providing knowledge of the severity of complications of parasitic diseases. It also provides insights into the interactions between parasites and animal hosts and their impact on infected animals. Interestingly, parasites in cattle can cause delayed growth rates, poor physical development and fertility, serious health-related issues, and death in infected cattle. Besides, several parasites may infect both animals and humans, causing public health concerns. The pathological changes are also observed through toxic, subtractive, inflammatory, allergic, obstructive, traumatic, necrotic, and immunosuppressive pathogenic mechanisms caused by parasites in cattle in a wide diverse host/parasite relationships. Parasites may also have the ability to cause tumors or tumor-like lesions in infected cattle.

The present book is organized with the aim to provide a comprehensive approach used in the identification of various images of parasites, the diagnosis of parasites, and prevention and control strategies to counteract parasitic diseases of cattle. It also provides knowledge of its distribution, epidemiology, lifecycle, morphology, clinical manifestations, diagnosis, prophylaxis, and therapeutic measures of parasitic diseases of cattle. The book also covers numerous informative tables and color images for the easy identification of parasites, their induced diseases, and updated information on suitable prevention and control measures. The book is well acceptable as both a textbook and a reference guide for students, academicians, researchers, field veterinarians, veterinarian nurses, laboratory staff, farm managers and also livestock owners. The book is systematically arranged and provides high-quality literature of international standards on organ-specific parasites and parasitic diseases in cattle and their diagnosis and therapeutic management. The book serves as a useful basic resource for all researchers, academics, and postgraduates wishing to gather knowledge on parasitic diseases, diagnosis, treatment, and prevention of cattle parasites and parasitic diseases with an aim to develop new antiparasitic drugs.
