Description
Swine pasteollosis is a serious infectious disease, which is characterized by infecting the blood of an animal with pathogenic microorganisms that cause hemorrhagic inflammation of the upper respiratory tract and intestines. 
This disease can often be diagnosed in conjunction with other diseases of pigs - plague and mug.
Causes and pathogens
One of the main causes of the disease pasteurellosis is the lack of hygiene standards in the pigsty.
High humidity, poor nutrition, a large number of pigs in the stall, weakened immunity, hypothermia - all these factors contribute to the reproduction of the pathogen, Gram-negative Pasteurella multicida. 
This microorganism has an oval shape (the shape of a capsule) and has morphological variability - it takes the form of some types of coccobacteria and ovoid.
A healthy animal may become ill after contact with a diseased individual, when consumed with pasteurella water and feed.
Pasteurellosis in piglets can occur when feeding milk from an infected sow. 
Symptoms of manifestation in various forms
The incubation period of pathogenic microorganisms Pasteurella multicida is from several hours to 3 days. The disease can occur in acute, over-acute and chronic forms. Let's look at the signs of pasteurellosis and features of the course of each form of the disease.
Sharp
The acute form of the disease is characterized by a rapid rise in temperature to 41 ° (38-39 ° is considered normal temperature in pigs), refusal to eat, shortness of breath, and the general state of the animal is oppressed.
There may be a cough, nasal discharge, often with blood. When pressing on the chest, the animal may react painfully. Developing cyanosis of the ears and mucous membranes. In the acute form of the disease, the animal rarely survives. Death occurs at 3-8 days. 
Super sharp
The super-acute form of pasteurellosis is similar in symptoms to the acute form of the disease. Neck swelling, thirst and heart failure are added, as a result of which the stomach, thighs and ears of a pig acquire a bluish tinge. The animal dies for 1-2 days.
Chronic
In some cases, some improvement occurs and the disease takes a chronic form.In this case, the symptoms of the disease remain coughing, swollen joints, the animal begins to lose weight and weaken rapidly, and eczema of the skin appears.
Increased body temperature is normal. In this case, the death of an infected pig occurs within 1-2 months. 
Diagnosis of the disease
The occurrence of at least one of the above symptoms is a reason to apply to the veterinary service. Sick animal must be urgently isolated.
In order to make an accurate diagnosis and eliminate the plague and pork erysipelas, laboratory studies are needed.
Also investigated are the kidneys, spleen, lungs, infiltration from the chest cavity.Treatment
For the treatment of pasteurellosis used antibiotic therapy. The following antibiotics - Tetracycline, Enrofloxacin, Dibiomycin, Levomycetin, Terramycin - effectively affect Pasteurella multicida.
Preventive measures
In order for your pigs not to suffer from pasteurellosis, it is necessary to monitor the implementation of sanitary and veterinary standards, among them the main ones are:
- timely introduction of serum against pigs pasteurellosis;
- regular room ventilation (but drafts should be avoided);
- providing animals with a healthy and balanced diet, clean drinking;
- regular vet check-ups;
