Due to the "cold spring" weather, the annual high incidence of pig disease from March to May is even more severe. The pigs in Tangxian County have recently suffered from swollen joints, jaundice, anemia, fever, abdominal and lower extremities, and the appearance of purpura. The author was diagnosed as a mixed infection of swine streptococcosis and Eperythrozoonosis with clinical diagnosis and laboratory tests. The treatment quickly controlled the disease. The relevant situation is reported as follows for reference by the reader. First, the incidence and clinical symptoms A pig farm has a total of 82 young pigs weighing 35 to 50 kg. Since the beginning of March 6, there have been 16 consecutive pigs. The livestock owner had used symptomatic treatments such as penicillin, aminopyrine, and viral spirits, resulting in poor results and three deaths. The clinic found that the pig farm had relatively poor sanitary conditions and the excreta was seriously contaminated. Diseased pigs are depressed, drowsiness, loss of appetite, and waste in later stages; body temperature 40.5°C to 42°C; chills, convulsions, and unstable standing; redness of the skin, especially in the tips of the ears, nose, legs, and tails, hand pressure Do not fade, visible yellow stained mucous membranes, breathing difficulty was a dog sitting posture, some pigs swollen joints, do not want to stand or walk, late-stage disease tea urine color, soy sauce feces. Second, necropsy and diagnosis The necropsy pigs showed poor blood coagulation, poor laryngeal and gingival haemorrhage; pulmonary congestion and enucleation, pericardial effusion, a lot of fibrin, coronal fat, myocardial hemorrhage; liver was yellow, gallbladder filling, bile atherosclerosis Thick; splenomegaly, bleeding on the surface; a large area of ​​the pylorus at the pyloric hemorrhage, severe gastric mucosa loss, red stomach contents, thickening of the bladder mucosa, diffuse bleeding. After bacteriological examination, a large number of chain-shaped cocci were observed. The susceptibility testing of the bacteria was carried out. As a result, it was found that lincomycin was highly sensitive, spectinomycin was moderately sensitive, and penicillin was insensitive. After microscopic examination of the blood pressure microscopy, it was found that a large number of parasites were attached around the red blood cells, and the morphology of the infected red blood cells changed, showing irregular shapes such as gears and starbursts, and tremors in the plasma or swinging up and down. According to the above, it was diagnosed as a mixed infection of S. suis and Eperythrozoon. Third, prevention and treatment 1. Sick pigs were given a "Gong Gong Fu Hong Ling" (main ingredient: triazepam), deep intramuscular injection once daily for 3 days. At the same time with "chain killing" (main components: lincomycin, spectinomycin) intramuscular injection once a day for 3 to 4 days. 2. The whole group of pigs were drinking with ciprofloxacin lactate, and at the same time the feed was chopped into the "red bow chain anti-dispersion" (main components: Artemisia annua, Anemarrhena, Astragalus, Licorice, Dioscorea), and 1 kg was added per ton of feed. 7 days. 3. Severely anemic pigs were injected with “Dextran Ironâ€, Compound Vitamin B, and Vitamin C. Helps to increase resistance and accelerate the recovery of pigs. 4. Strengthen the feeding and management of healthy pigs, do a good job in environmental sanitation, and do a good job of immunization against insects and other diseases; adhere to the regular disinfection system, and use “strong iodine†to disinfect pig houses and the environment; add the disease season to pig feed Sulfamonomethoxine sodium can effectively reduce the incidence of this disease.
