(1) Acute laryngeal anthrax in pigs
Laryngeal anthrax mainly invaded submandibular, retropharyngeal and anterior cervical lymph nodes, and there was no obvious inflammatory lesion in the lungs.
(2) pigs were exposed to contagious pleuropneumonia.
The lesions were confined to the respiratory system, and the liver lesions of pneumonia were even purplish red, while the lesions of swine pneumonia were wide, and there were often red liver lesions and gray liver lesions in the pneumonia area.
(3) Swine pant disease
The main symptoms of wheezing are asthma, cough, hypothermia, pancreatic or fleshy pneumonia with obvious boundary, bilateral lung lesions are symmetrical, and there is no suppuration or necrosis. It is obviously different from swine pneumonia.
