Acute and chronic infectious disease in chickens and turkeys causing sepsis. In chicks, similar symptoms to pullorum and the main symptom of chicken is septicemia as a digestive, egg transmission disease.
1. Agent
Salmonella gallinarum and serologically not able to distinguish with pullorum standard type then and classification of bacteria between pullorim and typhus byi serology alone is impossible. Therefore, by separating the bacteria should be performed in a number of biochemical tests. Resistance to heat is weak and kill easily, even weak to general disinfectant.
2. Epidemiology
Gave a tremendous loss to the poultry industry generates worldwide in the early 1900s still are occurring in certain countries, the incidence of brown layer than the white one is higher and lead to big damage, the transmission route are as follows.
① egg transmission
② through the feces of infected chickens spread to other flocks
③ vehicle or a person acting as an important propagation factor
④ infected by dogs and cats, and wild birds, insects, rodents
⑤ from the infected system to uninfected by cannibalism or spread over the wound
⑥ infection via feces of infected chicken
3. Clinical Signs and Autopsy Findings
1) Clinical Signs
The pale combs and crouching, sitting down with eyes closed and yellow or green diarrhea symptoms showed reduced feed intake, egg production is falling and there is a tendency that continues consistently to spread in one center is the other point. The increase is mainly due to the onset of stress caused by the heat in summer.
2) Autopsy Findings
① When a peracute mortality may not have the visual findings.
② In the case of acute, liver, spleen, and kidney enlargement findings of bleeding is observed, necrotic white spots on liver (common feature), egg yolk malabsorption and cream like or the amount of egg yolk content in cheese is observed.
③ The chicken with respiratory symptoms and sometimes is the white nodule formation, similar to that observed tumor nodules is observed in the case of Marek's disease on myocardium and pancreas. The number of chronic congestion in the liver and ascites is caused due to this. Similar nodules should also observed at gizzard, cecal wall and the large intestine.
 
4. Prevention and Treatment
1) Prevention
 ① thorough disinfection when access outsiders or vehicles in poultry farm.
② the prohibition of access dogs, cats, wild birds and exterminate rats and insects.
③ Since egg transmission disase, to buy a chick from uncontaminated GP farm.
④ chicken and pullet rearing is isolated.
⑤ chicken manure should not get in feed and water bucket.
