A pig farm in Zhangshu City, Jiangxi Province, raises 600 finishing pigs, all of which have been effectively vaccinated according to the immunization program against swine fever, swine erysipelas, swine pasteurellosis, Streptococcus suis, and other diseases. Recently, some pigs showed depression, reduced or lost appetite, body temperature of 40-41.8°C, anemia, and difficulty breathing. Most pigs were constipated, with lard-like mucus on the fecal pellets. In the middle and late stages, the ear wings, underside of the abdomen, and extremities of the limbs of sick pigs turned red first and then purple. The on-site veterinarian treated them with gentamicin, penicillin, sulfonamides, and other drugs combined with metamizole sodium, but the

A pig farm in Zhangshu City, Jiangxi Province, raises 600 finishing pigs, all of which have been effectively vaccinated according to the immunization program against swine fever, swine erysipelas, swine pasteurellosis, Streptococcus suis, and other diseases. Recently, some pigs showed depression, reduced or lost appetite, body temperature of 40-41.8°C, anemia, and difficulty breathing. Most pigs were constipated, with lard-like mucus on the fecal pellets. In the middle and late stages, the ear wings, underside of the abdomen, and extremities of the limbs of sick pigs turned red first and then purple. The on-site veterinarian treated them with gentamicin, penicillin, sulfonamides, and other drugs combined with metamizole sodium, but the effect was poor. After the fever subsided, once the medication was stopped, the high fever returned, and 12 pigs died successively. Necropsy of the dead pigs showed pale mucous membranes and skin, generalized jaundice, thin and incompletely coagulated blood, effusion in the body cavities, enlarged liver, gallbladder, and lymph nodes, and an enlarged and soft spleen. Based on the farm's immunization program, medication used, and lesion characteristics, the diagnosis was porcine eperythrozoonosis.

According to the diagnosis, use diminazene at 5-8 mg/kg, once a day by deep intramuscular injection, for 1-2 consecutive times, or a long-acting antibacterial agent produced by Jiangxi Minxing can also be used. If anemia is severe, drugs such as dextran can be injected at the same time. At the same time, improve environmental sanitation and eliminate all types of blood-sucking insects such as lice, mosquitoes, and flies.

Analysis: This disease is most easily confused with influenza, toxoplasmosis, swine fever, and other diseases. Therefore, clinically, do not draw conclusions lightly based only on symptoms. Compare more, perform more necropsies, and when necessary, send samples to the veterinary department for laboratory testing. This disease can occur in all four seasons, but is more common in summer and autumn. Based on diagnostic and treatment experience, we especially remind fellow veterinarians that when this disease has not been confirmed, the use of sulfonamide drugs is strictly prohibited; otherwise, it will worsen the condition and cause death.
