It can be shown as various pathological changes in morphological, which is one of the basic pathological processes that make up the disease, and is also an important basis for the discovery and diagnosis of disease. Often distinguished by degree of atrophy, degeneration and necrosis of three forms. The first two are reusable damage processes, cells can still maintain different levels of life activities, and necrosis is the cell's “death”, the irreversible process.  Atrophy The process by which organs, tissues, or cells that have developed mature, due to metabolic disorders of matter, cause dwindle and decreased physiological function. The decomposition and metabolism of atrophy cells exceeds that of anabolus, thus reducing the volume, the quantity decreases, and the physiological function decreases accordingly.……

Pasteur disease

Knowledge Title: Pasteur disease Other Title: pasteurellosis Knowledge Content:  A variety of livestock infectious diseases mainly caused by poly-killing pasteurella multocida. It happens all over the world.  The bacteria is two ends of the blunt circle, the central micro-convex short bacillus, Gram-dyed negative. Disease tissue or body fluid smear with Jim Sajid method or melanadon dyeing mirror examination, see the bacteria are more ovoid circular, both ends of coloring deep, the central part of the color ingressed shallow, very similar to the side-by-side two cocci, so also known as bipolar staining bacteria. There are many serotypes, according to the specific membrane antigen can be divided into A, B, C, D, E 5 serotypes, membrane antigen and bacterial antigen (represented by Arabic words 1 to 12, a total of 12 species) combined into 15 serotypes.  The acute case of the disease has bleeding and septic lesions, once known as hemorrhagic septicaemia.……
