Symptoms of E. coli in ducks, E. coli in ducks is a common disease, what are the symptoms of E. coli

The disease is mostly acute sepsis, the newly hatched ducklings are weak after the onset of the disease, the eyes are closed, the neck is closed, the abdominal circumference is larger, there are often diarrhea, and most of them die due to sepsis; Larger ducklings are depressed after the onset of the disease, loss of appetite, drooping wings, standing aside, head bent downward, the corners of the mouth touch the ground, the eyes and nostrils are often attached to the secretions, some sick ducks pull green loose stools, dyspnea, often due to sepsis or physical failure, dehydration death; Adult sick ducks like to lie down, reluctant to move, the abdominal circumference is swollen and sagging like a penguin when standing, there is a fluctuating sensation of fluid on palpation, and ascites is discharged by puncture. On autopsy, the liver is enlarged, bronze or bile-like, patin-green, brittle; The spleen is enlarged and has purple-black markings; ovarian hemorrhage, pulmonary congestion, hemorrhage and edema; The whole body serous membrane is characterized by acute exudative inflammation, and yellowish-white fibrinous exudate is attached to the surface of the pericardium, hepatic envelope and air sac wall; exudative inflammation of the peritoneum, yellowish ascites; catarrhal or necrotizing inflammation of the intestinal mucosa; Some sick ducks have broken yolk, and the abdominal cavity is mixed with yolk material; Some ducklings have incomplete yolk absorption and pathological changes such as metallitis. To confirm the diagnosis, it is necessary to send it to the laboratory for isolation and identification of pathogenic bacteria.

1.Rapid treatment of rod plasma is a dual serum antibody against Escherichia coli and serositis.

2.Rod-pulp quick treatment with cephalosporin, dosage, a bottle can ** 500 ducks, one injection can control a large group, and another injection can be injected for particularly serious ducks. **The rate can reach more than 90%.

The manifestations of E. coli and birds are more obvious, and it is necessary to be easy to diagnose, usually with closed eyes and neck napping, and it will be accompanied by white loose stools. There are no other obvious conditions, and E. coli is usually present. At this time, you can use florfenicol with doxycycline hydrochloride compatibility**, the effect is obvious, if you can't be sure whether it is an E. coli disease, you can consult Tianmeow Odier at any time.

There is a high probability that there will be difficulty breathing, abnormal bowel movements, it is likely to lead to septicemia, dehydration, some sticky discharge from the eyes and nostrils, loss of appetite, and listlessness.

Ducks have a bad appetite and look sluggish, ducks have difficulty breathing, cough symptoms, and diarrhea can become very lightweight, these diseases are all duck colibacillosis.

It can cause acute and chronic diseases, and then it can also cause sepsis, duck plague syndrome, which can lead to respiratory infections, and also cause ducks to lose energy and appetite.

<>1 Hail causes.

Wild duck colibacillosis is a bacterial infection caused by certain serotypes of Escherichia coli. The disease is mainly transmitted through the digestive tract, and can be transmitted through eggs contaminated with germs, feces and secretions of diseased wild ducks, as well as contaminated feed, drinking water, utensils, bedding, and activity places. The disease can occur all year round, but it tends to occur frequently in the rainy, humid and muggy autumn season.

2 Symptoms. The incubation period of the disease is 1-3 days, with sepsis being the most common. It is more common in mallards between 3 and 10 weeks of age.

Acute sick ducks died suddenly without showing symptoms, and the case fatality rate was as high as 50%; The main symptoms of non-acute sick ducks are: depression, loose feathers, inflammation of the conjunctiva, loss of appetite or even refusal to eat, nasal discharge, neck stretching and breathing, drowsiness, diarrhea, yellow-white or yellow-green thin feces, paralysis of the feet, unsteady standing, etc.

3 Prevention. E. coli is not very resistant and can be killed in 15 minutes at a temperature of 60. General disinfectants can kill the bacteria.

The preventive measures mainly include: Strengthen health management, regular cleaning and disinfection, ensure the hygiene of feed and drinking water, and strictly prevent other poultry from entering: The hatchery room and brooding room should be fumigated and disinfected with formaldehyde before and after use, and the eggs must be cleaned and disinfected before they can be incubated; For immunoprophylaxis, subcutaneous injection of E. coli multivalent ultrasonic-inactivated bacteria seedlings (less than 1 month old) in the back of the neck of wild ducks, generally 14-20 days old for the first time and 18-20 weeks of age for 1 time.

4．**。Kanamycin or spectinomycin, 30-40 mg intramuscularly per kilogram of body weight, once a day for 3 days; Streptomycin is injected intramuscularly at 10,000 units per kilogram of body weight, once a day for 3 days; With gentamicin, intramuscular injection according to the amount of 10,000 units per kilogram of body weight, 2 times a day, and chloramphenicol raw powder, evenly mixed into the feed according to the amount of feed section, the effect is obvious.

Summary. A duck's mental state of E. coli depends on its health, and if it is not infected with E. coli, then its mental state should be normal.

A duck's mental state of E. coli depends on its health, and if it is not infected with E. coli, then its mental state should be normal.

Fellow, I really didn't understand, I can be more specific.

Is it normal for ducks to have E. coli spirits? Not necessarily, E. coli spirits may affect the health of ducks. E. coli psycho is a common bacterium that can be spread through food, water, or the air, and it can cause symptoms such as diarrhea, fever, anemia, etc., in ducks.

To solve this problem, first ensure that the duck's diet and environmental hygiene or disturb the rock to adequate care. Eat and drink fresh, and wash drinking fountains frequently to prevent bacterial growth. In addition, the duck's cage should be cleaned regularly to prevent bacterial growth.

Antibiotics can be used if the duck is showing symptoms of E. coli, but the veterinarian's instructions should be followed to avoid it. Personal tip: Provide ducks with a good diet and environment, clean drinking fountains and cages regularly to prevent bacterial growth, and follow your veterinarian's instructions to use antibiotics**.

The main prevention of this disease is to do a good job in the sanitation of feed and drinking water in the duck house, improve the resistance of the duck flock, and eliminate various adverse factors that affect the growth of the duck. Pay attention to the ventilation and dryness of the duck house, do not feed moldy and deteriorated, polluted feed, clean and hygienic drinking water, pay attention to the insulation of ducklings, the feeding density should not be too large, and the nutrients of the feeding 4 should be comprehensive. Otherwise, even if some drugs are very effective for the disease, the condition will be ** after stopping the drug.

Duck houses and utensils should be disinfected regularly, usually once every 2 weeks, and twice a week when the disease is found.

(1) Preventive measures, mainly to do a good job in environmental sanitation and strengthen the management of duck breeding. In particular, attention should be paid to the following: check whether the water source is contaminated with E. coli and replace it completely if so; Pay attention to the heat preservation and feeding density during the brooding period, improve ventilation, reduce dust, be diligent in manure removal, and reduce the content of ammonia; Duck houses, incubators and utensils are cleaned and disinfected frequently; Duck farms should collect eggs in a timely manner.

Antibiotics can be used to prevent the occurrence of parasites and other diseases. (2) Inoculation of vaccines, the commonly used vaccines in China are Escherichia coli formaldehyde inactivated vaccine and Escherichia coli inactivated oil milk vaccine, it is best to use spontaneously diseased duck isolated E. coli strain to prepare multivalent vaccine for immunization, which can effectively control the occurrence of the disease.

Under normal circumstances, it is best to strengthen the management of feeding, it is best to disinfect the duck house frequently, ventilate, pay attention to drinking water, feed, and if possible, the duck flock can be collectively vaccinated

1.Do a good job of disinfection of duck eggs, incubators and hatchers, and the hatchery hall and its utensils should be cleaned and disinfected frequently.

2.Implement the "all-in, all-out" system, strengthen disinfection, brooding room, net bed and feeding equipment must be thoroughly cleaned and disinfected before reuse;

3.Strengthen management, reasonable density, pay attention to ventilation, change bedding frequently, and keep the house clean and dry.

Due to the wide distribution of E. coli in nature, healthy ducks are very susceptible to infection and become hermit carriers, so the length of the incubation period is very inconsistent. In duck farms with poor environmental sanitation conditions and extensive feeding management, the incidence and mortality of E. coli disease are relatively high, and most of them are acute sepsis. For example, after the onset of the disease, the newly hatched ducklings have weak constitution, closed eyes and necks, large abdominal circumference, often diarrhea, and mostly died of sepsis.

After the onset of the disease of the larger ducklings, the spirit is listless, the appetite is reduced, the neck is drowsy, the eyes and nostrils are often attached to the viscous secretions, some of the sick ducks discharge gray-green loose stools, dyspnea, often due to sepsis or physical failure, dehydration death. Adult sick ducks like to lie down, reluctant to move, when standing, the abdominal circumference can be seen to be swollen and drooping, penguin-shaped, palpation of the abdomen has a sense of fluid fluctuation, puncture has ascites outflow.
