Diagnosis and Prevention of Mixed Infection of Eperythrozoonosis in Piglets
In a pig farm in Zhoudian Village, Xuchang County, 80 pigs weighing 45 kg were reared. On Jun. 19, 2005, the disease suddenly developed. The body temperature increased to 41°C to 42°C. The skin was white and individual vomiting was diagnosed by local veterinarians. No name high fever. The use of aminopyrine, penicillin and other drugs to treat invalid, June 27 came to our hospital for diagnosis and treatment, clinical examination, autopsy, laboratory diagnosis was diagnosed as mixed infection of pseudorabies and Eperythrozoonosis in pigs. 1 Incidence The pig farm bought 80 piglets from the field in early May. After being bought back, swine fever vaccines, swine erysipelas, porcine combined vaccine and streptococcal vaccine were injected. On June 19th, the pig suddenly became ill. The body temperature increased to 41°C-42°C. The appetite decreased or was abandoned. The spirit was depressed, the skin was whitened, and vomiting began. The aminopyrine, penicillin, dexamethasone, and clindamycin were used. With drug treatment, the effect was not only not obvious, but the more severe the disease was, the worse the condition continued to develop. As of June 27, the incidence was 23 and 7 deaths. 2 clinical symptoms Increased body temperature to 41°C to 42°C, loss of appetite or waste, depression, vomiting, purple eyes, eye discharge, difficulty breathing, skin whitening, severe skin (inside of leg), purple, pull dry Excrement, some diarrhea faeces have bad odor, red urine, individual convulsions, walking instability. 3 pathological changes Thin blood, laryngeal edema, bleeding in the throat mucosa, bleeding at the bottom of the stomach, liver enlargement, pale kidney, bleeding, swollen spleen, enlarged lymph nodes, bleeding bladder mucosa. 4 laboratory diagnosis 4.1 Bacterial culture Sterilely inoculate on common medium, incubate at 37°C, observe the results after 24 hours, grow aseptically. 4.2 Fresh blood pressure microscopy Take a drop of ear tip blood of febrile pigs, add the same amount of normal saline, drip on the slide glass, cover the glass slides, under the oil lens, the red blood cells show irregular shapes such as pineapple shape, stick shape, and the surface covered with transparent small particles . 4.3 Serological examination Using a latex agglutination test, 9 serum samples from the sick pigs were collected. As a result, 7 serum samples were found to be positive. 5 Prevention measures Isolation of sick pigs, with 5% to 10% strong disinfection, thorough disinfection of pig houses, feeding troughs and tools. For those pigs that did not develop the disease, the pseudorabies attenuated vaccine was used for emergency prevention. Each 5 ml of muscle was injected intramuscularly and drinking water was electrolyzed. After two days, there were two pigs. Afterwards, there was no recurrence of the pig and the transmission was stopped. Treatment with interleukin-2, intramuscular injection at 1 ml per 20 kg body weight, once daily for 3 days; simultaneous use of long-acting oxytetracycline (demimin) 0.1 ml/kg body weight, intramuscularly, once daily 3 days; compound astragalus polysaccharides, intramuscular injection of 0.1 ml per kilogram of body weight; 800 grams of oxytetracycline powder per kilogram of feed, fed continuously for 5 days, 7 days after the recovery of sick pigs.
Respiratory disease is a common disease, frequently-occurring disease, the main lesion in the trachea, bronchi, lung and chest, lesions are more cough, chest pain, respiratory effects, severe breathing difficulties, hypoxia, and even respiratory failure and death. Due to air pollution, smoking and other factors, The chronic obstructive pulmonary disease is increasing including chronic bronchitis, emphysema, pulmonary heart disease, bronchial asthma, lung cancer, pulmonary diffuse interstitial fibrosis, and pulmonary infection the morbidity and mortality of the disease at home and abroad . Therefore, Anti-Respiratory disease drugs are also more and more attention paid by researchers. Respiratory disease have the symptoms of cough, sputum, hemoptysis, chest pain, shortness of breath and other symptoms of lack of specificity, often clinicians mistaken by people for colds, bronchitis, and severe pneumonia, tuberculosis or lung cancer and other diseases delayed diagnosis; Respiratory tract infection, to be developed to emphysema, pulmonary heart disease, respiratory failure was taken seriously, but it was too late, its pathology and physiological function has been difficult to reverse. As with other systemic diseases, careful and detailed medical history and physical examination are the basis for the diagnosis of respiratory diseases, and should be combined with routine laboratory tests and other special findings to conduct a comprehensive and comprehensive analysis. Currently the most clinical application of anti-respiratory disease drugs have the following four categories: 1. Antihistamines 2. Cough medicine 3. Bronchodilator 4. Expectorant 5. Anti-asthma Drugs.
