Symptoms of E. coli infection in the lungs

E. coli infection can cause serious harm to our health, because it is a mixed infection of bacteria and viruses. If it is not effectively treated and controlled, it may even pose a threat to life. Therefore, we must scientifically recognize and understand the symptoms and treatments of the infection.

1. Respiratory Escherichia coli disease:

It mainly attacks the respiratory tract, often manifested as dyspnea, slight changes in feces with more yellow and white loose feces, a slight decrease in the egg production rate of laying hens, and a slightly lighter egg color.

2. Enteritis-type Escherichia coli disease:

It mainly attacks the digestive system, often showing symptoms of enteritis, loose stools, and obvious changes in egg production and eggshell color in laying hens.

3. Yolk peritonitis type Escherichia coli disease:

The main invaders harm the reproductive system. It often occurs in chickens during the peak period and after the peak, and there is no obvious seasonality in the disease. It usually occurs in summer and autumn. The egg production rate of laying hens has declined, and policy makers have stopped producing eggs. There are more soft-skinned and sand-skinned eggs, the combs are purple, and the feces are mostly yellow and white. Sick chickens are fatter and have larger abdomens, which are also called "water crotch" or "egg crotch". Sick and dead chickens often have egg retention in the posterior part of the oviduct, that is, there is an undischarged hard-shelled egg in the cloaca.

4. Breathing type:

Generally, there is bleeding in the tracheal rings, and in severe cases, there is grayish-white necrosis at the edge of the air sac. Clinically, attention should be paid to distinguish it from mycoplasma and atypical Newcastle disease.

5. Enteritis type:

Bleeding in various parts of the intestine. Especially bleeding in the duodenum and small intestine. In severe cases, edema may also occur. The intestinal lining is red. There is a layer of golden or white reticular fibers on the liver and heart.

6. Yolk peritonitis type:

The autopsy showed necrosis or degeneration of ovarian follicles, atrophy of fallopian tubes, ulceration of the inner wall, swelling of the kidneys, urate deposition, enlarged and fragile liver, intestinal bleeding, and the abdominal cavity filled with yolk or turbid fluid. (Bleeding lesions inside the fallopian tube)
