Eperythrozoonosis in pigs has a high infection rate. Anemic infections and secondary infections often occur in sick pigs, causing serious economic losses to farmers. The differential diagnosis method of eperythrozoonosis is described as follows:
When Eperythrozoonosis occurs in pigs, the body temperature of the pig is high (40.5°C～41.5°C), the skin of the ear, abdomen, and the inner side of the femur is reddish, and the conjunctiva of the eye is pale, trembling, and cold after first flushing. The mesenteric lymph nodes of the diseased pigs were dark purple, and the surrounding area was marbled. There was a small spot of hemorrhage under the kidney capsule. The renal pelvis and kidney papilla had needle-point bleeding points. Splenomegaly, purple infarcts with large granules up to the edges of the soy beans.
Porcine pulmonary epididymal disease and swine adnexal fine brain disease symptoms are similar: high body temperature (41 °C ~ 42 °C), ear, chest, ventral, femoral skin reddish purple, wheezing, difficulty breathing, dog sitting and so on. Symptoms of different throat throat neck swelling, mouth flow nasal fluid. Hemorrhagic serous infiltration of connective tissue in and around the throat. The pleura has fibrous pneumonia, marble cut surface, antibiotics and timely treatment is effective.
Pig asthma and swine erythropoietin symptoms are similar to infectious asthma, dyspnea, high body temperature (above 40 ° C) and so on. Symptoms of different body temperature are generally not high, cough is sputum, there is a small amount of skin surface bleeding hemorrhoids.
Toxoplasmosis in pigs is similar to Eperythrozoonosis in pigs: high body temperature (40°C～42°C), loss of appetite or waste, mental atrophy, fecal dryness, dryness and thinning, rapid breathing, difficulty, ear Lower limbs, lower abdomen skin visible purple spots. Symptoms of different flow of nasal fluid, the body of the brain when invading the brain with epilepsy spasticity, hindquarters paralysis. The autopsy showed lung redness or orange yellow enlargement, luster, bleeding on the surface, and medullary lymph node swelling in the medullary canal. If the cord was thick, there was a large bleeding point on the cut surface. The ileocecal valve has a superficial superficial ulcer, and the cryptococcal and colon can be seen with scattered pinky and central depressions, and sulfa drugs are effective. Blue Ear disease and swine eperythrozoonosis similar to the symptoms of piglets swine flu symptoms, some birth or death or "mummy", pregnant sows, about one hundred days, suddenly appeared anorexia, high or low body temperature, nasal clearing , The tip of the nose is cold, hi sleepy and sleepy. Symptoms of the ears at the tip of the ear were blue-purple, individual pigs were itchy, and the nose was rubbed with the ground. They were extremely uneasy, and most of the sows had died, or exceeded the expected date of production. Vulvae exuded brownish white thick secretions. Repeated infertility, with individual abortions, can produce weak piglets and die after less than 24 hours. Individual piglets experienced difficulty in breathing. The ears and nose were blue-purple and most died. 50 to 60 days after weaning, there were also a few blue ears in piglets, which subsided two days later.
Symptoms of porcine contagious pleuropneumoniae and Eperythrozoonosis in pigs are similar to those in high temperatures (40.2°C to 42.7°C), dyspnea, canine sitting, blue-purple blue of the ears, nose, and extremities; With interstitial edema and so on. Symptoms varied from April to May and from September to November. They occurred frequently from 6 weeks to 6 months of age, and bubble-like hemorrhagic secretions flowed from the nose and mouth. The autopsy showed fibrous exudate attachments on the surface of the pleura and lungs, and antibiotics were effective in timely treatment. Eperythrozoon-suffered pigs are often accompanied by bacterial, viral, or parasitic diseases such as streptococcal disease, swine edema disease, piglet paratyphoid fever, swine lung disease, swine erysipelas, swine fever, and toxoplasmosis. These pathogens are liable to contaminate the environment of the pig house, reduce the resistance of the infected pigs, and present a mixed infection, resulting in high mortality and huge economic losses. Therefore, in clinical practice, we should pay full attention to it and give appropriate symptomatic treatment to ensure safety.
