It details the vectors of animal and human diseases such as Rocky Mountain Spotted Fever, Tick Paralysis, and Tularaemia, and offers groundbreaking observations and experiments on their feeding habits, including the various stages of tick development and their impact on the rate of tick feeding. The author provides a necessary foundation with a detailed description of tick anatomy and the process of digestion, along with cultural and laboratory techniques for studying tick flora. They provide histological and cultural studies on pathogenic and non-infectious organisms, paying particular attention to symbionts. The book also explores the lesser-known microorganisms invading tick tissues and provides an indicative analysis of host and tick tissues in relation to varying feeding rates of individual ticks.
