Diagnosis and treatment of a secondary case of Haemophilus parasuis

Recently, I was diagnosed with a hairy pig in a pig farm with a body weight of about 15 kg. The clinical symptoms of the pig were fever, joint swelling, difficulty breathing, and limb cramps. In addition, according to the sampler, the pig farm had a prevalence of blue ear disease some time ago. Therefore, in order to confirm the source of the disease, my laboratory staff has dissected the pig. The specific lesions are now expressed as follows:

First, the necropsy lesions:

1. The joint is swollen, and the liquid is clear and the amount is large.

2, pericardial effusion, fibrin adhesion on the surface of the myocardium, forming a villus heart.

3, pneumonia

4, cellulosic pleurisy. The pleura and pericardium form adhesions, and the pleural cavity is yellow and turbid.

5. Diffuse peritonitis.

6, the corpse is incomplete.

Second, the treatment plan:

According to the necropsy lesions of the affected pigs and the symptoms of the sampled population, it can be judged that the sick pig is a Haemophilus parasuis that is secondary to infection after infection with blue ear disease, so the following treatment plan was given in the diagnostic room:

1. Injecting ceftiofur sodium or quinolones into the affected pigs can also be used in combination.

2. Add 500-1000 grams of Ding Zhukang per ton of drinking water, 600 grams of Vitocon, 5 kilograms of citric acid, and 20 kilograms of glucose for continuous use.

3. Due to the prevalence of blue ear disease in the farm, pigs with fever can be treated with Qingyu Baidu Powder. Dosage is 50-100g mixed with feed, once a day, for 3-5 days.

Third, the preventive health measures of the pig:

1. Prevention:

Piglets: By-pass pigs According to the age of the piglets, our company recommends the first ban at 14-35 days of age. If necessary, strengthen the immunization once every 3 weeks and choose Haibolai's vaccine.

Sow: 4 ml of the piglet vaccine is vaccinated about 30 days before the birth.

2. Health care:

Piglets in the delivery room are treated with cephalosporins such as ceftiofur at the age of 3, 7 and 21 days; the broodstock can be used for larvae for health care.

3. Keep the pig house warm and ventilated.

4. Reduce stress.

5, less mixed group, to achieve all in and out.

In summary, we will prevent the blue ear disease of the blue ear disease on the farm, eliminate the harm of the immunosuppressive disease to the pigs, and inoculate the piglet vaccine according to the age of the piglet causing Haemophilus parasuis. Strengthen feeding management and environmental disinfection, reduce various stresses, and select effective drugs to protect the pigs. Only in this way can the prevention of parasitic bacillary disease be in place, so that the pigs can be healthy and stable.
