Detailed explanation of pigs support primary pneumonia and common sense of medication and vaccine prevention and control

Pig pneumonia pneumonia is mainly a chronic pneumonia produced by the lung disease caused by the pulmonary lesions caused by the infection of the pentalide.It is one of the three major diseases of the pig farm. It is mainly manifested in the dyspnea of pigs, and the respiratory tract will be harmed. Pigs will have symptoms such as cough and asthma. This symptom is usually called pig gas asthma.One of the three major difficulty in controlling diseases, high incidence, low mortality rate, sick pigs are gradual weight loss, delaying the column, and the key to opening other diseases.

The chlamydia of pork pultomitis belongs to the genus of the mycoplasma, without cell walls, presented, spherical, circular, and silk; in the external environment, the adaptering ability of the chlamydia of the pentalitis is not strong. Generally, in the case of room temperature, the survival time does not exceed 36 hours.Portitis chlamydia is resistant to low temperature, and it can be stored with low temperature and frozen drying methods.Gram -dyeing negative; not strong resistance to external environment and physical and chemical factors, slow, complicated and difficult to be separated, and it is easy to be polluted; it can grow outside the cells, planted on the cilia of the respiratory tract, and cause cilia damage.

The chlamydia of pork pultomitis has multiple pathogen proteins, which can be planted on the cilia of the respiratory tract. Cell damage causes the swing to weaken back and forth, and its removal function decreases significantly.After the pork pultomitis is infected with pigs and planted, it can cause a large amount of lung macrophages and lymphocytes, cause local inflammatory reactions, cause lung damage, change alveolar macrophage function, leading to the decline of swallowing and clearing the function, continuous infection infectionAfter the pylinitis chriocyte infection, the pigs can also cause immunosuppressive suppression, resulting in a decline in their resistance and led to secondary infection.

The chlamydia of pneumonia is indirectly transmitted to the group through direct contact or droplets, and regardless of age.Bringe piglets are the main source of infection of pig pulmonary mycoplasma. Pentalitis mycoplasma can be transmitted to piglets from breeding pigs, and can also be spread horizontally, such as transmission through the respiratory tract, including nasal contact, sneezing, cough and other channels.The chlamydia of pork pultomitis can be transmitted through air within 3.2 km to 4.8 km. One significant feature is that the infection between pigs is slow.

It can be divided into three types: acute, chronic, and hidden type according to the onset.

4.1 The acute type generally manifested as a sudden onset, mental weakness, decreased appetite, shortness of breath, cough, panting, in severe cases of abdominal breathing or dog sitting posture, foaming nose, low cough, and asthma.Most of them are pregnant, mammal rocks and piglets.

4.2 Chronic types are mostly shifted from acute type, with a long course of the disease, long -term cough, light and crispy cough, short cough, weak and cough, which does not affect the amount of pigs’ feeding.From light to heavy, severe consecutive spasm coughs occur, the sick pig stands straight, the arched back stretchs the neck and hangs the head until the secretion coughs and swallows.This type is often issued in fattening pigs, reserve sow.

4.3 The hidden type is asymptomatic, and it is usually not onset.In the case of large temperature difference between day and night and temperature mutation, symptoms of respiratory diseases often show the symptoms of respiratory diseases.

After the pneumonia is infected with chlamydia, it will appear in the anterior abdomen of the lung tip, heart lobe, lobe, and intermediate lobe in its lung leaf leaf, heart lobe, lobe, and intermediate lobe.Symmetry "meat -like changes".

Portitis chirotrophic is a type of pathogenic bacteria without cell walls. Therefore, drugs that can exert bacteriostatic or bactericidal effects by inhibiting or destroying bacterial cell walls are usually not ideal for pig pulmonary mycoplasma.Drugs that can inhibit or kill pork pultis mycoplasma mainly include Thai Miaoxin, Large Larnectone, and Linkamines.The chlamydia of pork pultomitis is the most sensitive to Thai Miaoyuin and Ciscourse, followed by tetracycline and doxylin, Tellenecin, Type Star, and Fluinni Kao.

Treatment programs

6.1 Thai Miao Magniculin 10 mg/kg, muscle injection, 1 time/d, 3-5 days in a row.

6.2 Linkicillin 50 mg/kg.bw, muscle injection, 1/day, for 1 week.

6.3 Sulfinicate muscle injection, 50,000 to 70,000 IU/Kg.BW, 2 times/day, for 1 week.When the condition is serious, it can be sustained for 2 to 3 weeks.

6.4 The whole group of mixing medicine is used at the same time.You can add stagnomycin or beamis or titanicin to drink water or feed.

Symptoms of cough and asthma can be eased. You can try to use shampioxin or ammonia alkaline hydrochloric acid hydrochloric acid. Symptoms of symptomatic muscles can greatly relieve symptoms.

The chlamydia of pneumonia is indirectly transmitted to the group through direct contact or droplets, and regardless of age.Therefore, the immunity for pig branch pneumonia is still mainly vaccine immunity.According to the state of antigen, pneumonia vaccines can be divided into weak toxic vaccines (live vaccines) and active vaccines.

7.1 The mechanism of active vaccine and activation vaccine

The chlamydia of pork pultomitis is mainly acting on the respiratory mucosa, while the live vaccine spray nose or internal internal injection of the lungs can directly act on the respiratory mucosa, causing it to produce body fluid immunity, cellular immunity, and position immunity.Completely immune.

Activated vaccines can be feeded and injected, and the active vaccine antibody can be delivered to the lungs with the help of blood circulation. It can neutralize or directly kill the pig pulmonitis in the pigment and blood circulation system in order to control the piglets to control the pigletsPlastinate pneumonia.However, this vaccine can not have a good immune effect on the branches on the pigment’s mucosa and respiratory tract cilia.

7.2 Vaccine use

The best injection time of piglets should be selected for about 7 days after the birth of the piglets, and nasal spray immunity can be performed. This method is relatively simple, with less adverse reactions, which can quickly produce positions and achieve good immune effects.When a piglets are found to have pneumonia pneumonia, they should be isolated in time to avoid other healthy piglets infected.For piglets with piglet pneumonia, vaccine injection is performed.

7.3 Precautions for vaccine use

Before immune to piglets, other drugs that have effects with mycoplasma cannot be used.Sulfid drugs are not suitable for use before and after vaccine immunity, and avoid vaccine immunity to reduce the reducing effect of sulfa drugs and vaccines.In addition, for long -acting Ennoshaxing and long -acting earthycin drugs, use it during vaccine immunization.
