Chicken rhinitis is caused by Haemophilus.

Haemophilus chicken is pleomorphic. At the time of initial isolation, it was a gram-negative bacillus with bipolar staining, no spores, no capsule, no flagella, and could not move. The cell is rod-shaped or ball-shaped, and has a filamentous tendency. After degeneration, fragments and irregular shapes appear, and the typical rod-shaped or ball-shaped state can be restored by moving it to the fresh medium.

The incidence of chicken rhinitis: it occurs in chickens of all ages, and the infection of aged chickens is more serious. Pheasants, guinea fowls and quails can occasionally get sick, but the nature of the disease is different from that of chickens and has toxic reactions.

Symptoms of chicken rhinitis:

The damage of the disease in patients with inflammation in the nasal cavity and paranasal sinuses often only show the flow of thin clear fluid in the nasal cavity, and then turn into serous mucous secretions in the nostrils, sometimes sneezing. Facial swelling or edema, conjunctivitis, eyelid swelling. Loss of appetite and drinking water, or diarrhea, weight loss. Sick chickens are depressed in spirit, avoid puffiness, shrink their heads and stand stiff. The growth of chickens is poor, the number of eggs laid by adult hens is reduced, and the meat beard of Roosters is often enlarged. If the inflammation spreads to the lower respiratory tract, it is difficult to breathe. The sick chicken often shakes its head to expel the mucus from the respiratory tract and has rales. The throat can also accumulate clots with secretions. These are typical symptoms.

Because chicken rhinitis is similar to chronic respiratory disease, chronic chicken cholera, fowlpox, and vitamin deficiency, it is difficult to diagnose and is easy to be complicated with infection.

Chicken rhinitis has high incidence and low mortality, but it is easy to die from chronic respiratory diseases, colibacillosis, pullorum and so on.

The morbidity and death of breeding chickens were less, and the number of dead Amoy hens was less than that of laying hens in the late epidemic period. The main pathological changes were acute catarrhal inflammation of the nasal cavity and sinus mucosa, congestion and swelling of the mucosa, covered with a large amount of mucus on the surface, exudate clots in the sinus, and then cheese-like necrosis. Common catarrhal conjunctivitis, conjunctival congestion and swelling. Subcutaneous edema of the face and beard. In severe cases, inflammation of tracheal mucosa can be seen, with occasional pneumonia and pneumonitis.

Prevention of chicken rhinitis:

1. Heating equipment and automatic control ventilation device should be installed, which can obviously reduce the concentration of ammonia in the chicken house.

2. By taking chickens to disinfect the dust in the air and purify the air, it has played a positive role in the prevention and control of the disease.

3. Strengthening the cleaning and disinfection of drinking water appliances and the disinfection of drinking water are regular measures to prevent diseases.

4. Chicken farm staff should strictly implement the epidemic prevention system, such as changing clothes, bathing, changing shoes and so on. When more than one person has to go to the house due to the needs of the work, the chicken will be disinfected immediately after the work is finished.

5. The chicken house, especially the sick chicken house, is a highly polluted place, so we must pay great attention to the cleaning and disinfection of the chicken house.

The disinfection of the environment outside the chicken house and the removal of weeds and dirt can also be ignored. Therefore, comprehensive prevention and control is an indispensable important measure to prevent the occurrence of this disease.

Haemophilus parachuis is very sensitive to sulfonamides and is the first choice for the treatment of this disease.

Classic scheme for prevention and treatment of chicken rhinitis: sodium sulfamethoxine + azithromycin

In the morning: sulfamethoxine sodium (2000 jin water ∕ bag) concentrated drinking water for 5 days.
