Pathogens and pathogens The pathogen of foot-and-mouth disease infection is foot-and-mouth disease virus. Foot-and-mouth disease virus can be divided into four types of AOCZB poisons, and there is no mutual immune function among various types. The source of infectious diseases is diseased livestock, which is mainly transmitted through the digestive tract and respiratory tract, as well as infections. It can occur throughout the year, but it occurs more in autumn and winter and spring. 2. Symptoms of early onset of symptoms: Increased body temperature, decreased appetite, depression, shut-off, runny nose, otter vesicles are more common in limbs, mild lameness, and goat blisters are more common in the oral cavity. After 1-2 days, the blisters rupture and form plaques. Then they gradually heal. If they are not properly treated, they will continue to be infected with pyogenic bacteria and form ulcers and necrosis. If other complications do not occur, they generally heal well and have a low mortality rate. Lambs sometimes develop bloody gastroenteritis and myocarditis with high mortality rates. 3.
