Knowra Animal diseases Animal diseases Animal diseases are disorders that impair an animal’s health or function, arising from infectious agents, inherited traits, nutritional deficits, or environmental conditions.
Pathogenesis : The biological process by which a disease develops and produces damage or dysfunction. It traces how an animal disease progresses from its cause to its effects.
Veterinary medicine : The branch of medicine concerned with preventing, diagnosing, and treating disease in animals. It provides the clinical framework for addressing animal diseases.
Rabies : A viral disease of the nervous system, usually transmitted through the bite of an infected mammal. Rabies illustrates a lethal animal infection that can also threaten humans.
Infectious disease : A disease caused by a pathogen that can invade or replicate within a host. Infectious animal diseases may spread between animals or across species.
Animal welfare : The physical and mental state of an animal in relation to its living conditions and treatment. Pain, disability, and distress make disease a direct welfare concern.
Zoonosis : An infectious disease that can be transmitted between animals and humans. Some animal diseases cross species boundaries and become human health risks.
Veterinary diagnosis : The identification of an animal’s disease through clinical assessment and diagnostic tests. Diagnosis distinguishes among conditions that can produce similar signs.
Foot-and-mouth disease : A highly contagious viral disease affecting cloven-hoofed animals such as cattle, pigs, and sheep. Its rapid spread can trigger major livestock and trade disruptions.
Noncommunicable disease : A disease that does not spread directly between organisms. Many animal disorders arise from inherited, nutritional, or environmental causes instead of transmission.
Livestock disease : Disease affecting animals raised for food, fiber, labor, or other agricultural uses. Illness in livestock can reduce productivity and threaten food supply.
