What are the prevention and treatment methods for necrobacillosis in deer?
I. Epidemic characteristics Necrobacillosis in deer mostly occurs in deer herds in autumn and winter. During the autumn breeding period, male deer suffer hoof injuries from butting, and during the lactation period and grouping period, young deer suffer trampling injuries to the hooves, leading to infection and disease. In addition, when the exercise yard is uneven, has foreign objects, standing water or mud

Symptoms and Prevention of Infectious Pancreatic Necrosis in Salmonids
Pathogen: The pathogen is infectious pancreatic necrosis virus. Transmission routes: vertical transmission: eggs and milt of virus-carrying broodfish; horizontal transmission: feces, urine and secretions of diseased fish carry the virus into the water, and the routes of infection are the gills and mouth. Symptoms: juvenile fish weighing more than 5 grams are mostly chronic cases, with slower death; externally, the abdomen is distended, the body color darkens, the eyeballs protrude, the fin bases and abdomen are congested and red, the anus mostly trails string-like feces, swimming is slow, and feeding is poor. Fry weighing less than 5 grams are mostly acute cases, with rapid death; diseased fish move sluggishly

Infectious hematopoietic necrosis (IHN) of fish is a viral disease
[Pathogen] The pathogen of infectious hematopoietic necrosis of fish is infectious hematopoietic necrosis virus (abbreviated IHNV). [Symptoms and pathological changes] Affected fish initially show slow swimming and drift downstream, then swim with a swaying motion, and subsequently float up and roll sideways, often dying shortly after violent swimming. The diseased fish have darkened body color, protruding eyeballs, a distended abdomen, congestion at the base of the fins, and often a long, thick white mucous string hanging from the anus. On necropsy, a large amount of fluid is visible in the abdominal cavity, the liver, spleen and kidney are pale in color, the intestine is hemorrhagic, and the oral wall and skeletal muscle

How to surgically treat intestinal necrosis caused by umbilical hernia in pigs
If a pig's umbilical hernia is treated in time, it is generally very easy to cure and intestinal necrosis will not occur; if treatment is delayed, the intestinal tract that has fallen into the hernial sac will undergo necrosis. In most cases where necrosis occurs, the hernial ring is relatively small, and the fallen intestinal tract undergoes necrosis due to insufficient blood supply caused by strangulation by the hernial ring; in a few cases, although the hernial ring is large, the fallen intestinal tract undergoes necrosis due to prolonged stimulation by the contents (even putrid contents). Based on the circumstances, we have used surgery to treat many cases of intestinal necrosis caused by umbilical hernia in pigs, with good results,

What is infectious hematopoietic necrosis in salmonids?
Pathogen The pathogen is infectious hematopoietic necrosis virus. Transmission routes Vertical transmission: eggs and milt of virus-carrying broodfish, with transmission through eggs being more likely; horizontal transmission: contamination of water sources, etc. The virus mainly enters the fish body through the gills and digestive tract. Symptoms The disease often causes sudden mass mortality during the fry and juvenile stages, with onset generally occurring 7 to 14 days after infection. Diseased fish swim sluggishly, exhibit spinning movements, sometimes sink to the bottom, have darkened body color, a distended abdomen, congested fin bases, opaque mucous-like feces hanging from the anus, and "V"-shaped

What diseases cause skin bleeding and necrosis in chickens?
Diseases in chickens that cause skin bleeding, necrosis and other lesions include: [Colibacillosis (cutaneous form)] Similar symptoms: omphalitis, dermatitis. Distinguishing symptoms: omphalitis in chicks, dermatitis, necrosis and ulceration in growing chickens, some forming purple scabs; Gram-negative small bacilli visible on smear microscopy. Treatment: norfloxacin 0.5g/kg feed, fed continuously for 3-5 days; or ciprofloxacin, 0.1-0.3g per kg water, drunk continuously for 3-5 days; with chloramphenicol, add 1
