More than 150 internationally recognized experts contribute chapters on topics in their field of specialty. Clear and logical organization of chapters provides a solid basis for an approach to diseases caused by specific pathogens, with the first part of the book including sections on diagnostic approaches, treatments (including recommended antimicrobial drug doses), and prevention. Specific pathogens are addressed in the second part of the book, using a structured approach that includes etiology/epidemiology (relevance to wildlife animal hosts, role of the environment), clinical and laboratory findings, treatment, prevention, and public health implications. Case examples illustrate principles and highlight how the material can be applied. More than 800 clinical images, maps, life cycles, and photomicrographs assist with accurate understanding of epidemiology, pathogenesis, diagnosis of disease, and disease prevention. Visually appealing maps and life-cycle drawings enhance your comprehension and retention of the material. Convenient drug dosage tables in each chapter provide complete prescribing information; chapters on antimicrobial drugs in the first part of the book summarize pharmacokinetics, indications, contraindications, handling and administration guidelines; and dosage recommendations are made for antivirals, antibacterials, antifungals, antiprotozoals, and antiparasitic drugs. The book emphasizes approaches to optimize antimicrobial stewardship. Clinical Problems section helps you understand what infectious diseases should be considered in animals seen with clinical signs relating to different organ systems. Suggested readings and references are listed in each chapter, facilitating further research and study.
