Symptoms of contagious pleuropneumonia

summary

The pathogen is Actinobacillus pleuropneumoniae, which mainly exists in the respiratory tract of diseased pigs and spreads through air droplets. Pigs of all ages are easy to be infected, but pigs of 3 months age are the most susceptible to infection.

Symptoms of contagious pleuropneumonia

This disease is very similar to atypical classical swine fever. High fever is missed. There are bleeding spots on the skin under the ear and abdomen, and it turns purple. The most acute type of sudden death is often seen without any symptoms before death. The body of the dead pig is cyanotic at the end of the body, and the red foam is flowing out of the mouth and nose. The acute type is manifested by elevated body temperature, dyspnea, mouth opening, tongue and ear cyanosis. If not treated, it can suffocate within 1-2 days. Chronic type has intermittent cough, loss of appetite, sometimes lameness, joint swelling, with the delay of time, symptoms gradually subside, often self recovery.

The diagnosis can be made according to the symptoms and progress of the disease in individuals and groups, postmortem anatomical changes, isolation of bacteria from respiratory tract and serological test. In the differential diagnosis, the acute death and high temperature of the disease need to exclude classical swine fever; Pleuropneumonia with cellulose should be distinguished from Streptococcosis; It should be different from swine wheezing disease to change from competitive to chronic; In addition, the change of pneumonia should be different from that of swine pulmonary disease.

Acute death can be seen in both sides of the lungs are severe pneumonia, purple red, hard texture, solid cut liver tissue, trachea and bronchi filled with foam like blood like exudates, the chest cavity has a light red or yellow exudate, slightly longer course of disease, fibrous exudates on the lung surface, abscess like nodules.
