Infectious Diseases Overview Pathogens such as bacteria, viruses, spirochetes and fungi invade the rabbit body and rapidly grow and multiply, destroying normal physiological functions of the body, causing a series of pathological reactions, and causing infectious diseases, which are called infectious diseases. The difference between an infectious disease and an ordinary disease lies in: First, it takes a certain incubation period from invasion of the pathogen to the occurrence of symptoms; Second, it causes contagion that causes most meat rabbits to suffer from the same disease; Third, it often occurs after a certain period of time or after recovery. Lifelong and no longer feel the immunity of the disease; Fourth, infectious diseases are extremely harmful, acute infectious diseases, rapid spread, severe symptoms, high mortality; chronic infectious diseases long duration, symptoms are not obvious, although the mortality is not too high , but can reduce the production performance, and even some diseases can spread to humans. Therefore, eliminating and controlling the occurrence of infectious diseases is one of the important measures to ensure the development of the rabbit industry. China Agricultural Network Editor
