An Investigation And Preventive And Therapeutic Study On The Swine High Fever Syndrome Of Nanyang

From last year,An unnamed high fever outbreak in many areas of Henan fashion.Rush skin disease early,especially the abdomen,ears and limbs for later large purple,Autopsy systemic disease characterized by lymphatic edema.After the clinical investigation and study,the autopsy pathologicalchange and the cause of disease cause of disease analysis。the crownnamed"the pig high fever synthesis drafted"and proposed guarded against the system measure.All the infected pigs'temperture risesd in 2-4 dpi,and some pigs'temperture reached 42℃,most pigs dead in 34dpi-50dpi.Emaciation,extrados,hilch,cough,dyspnea etc clinic symptoms of these pigs were found.Interstitial pneumonia,carnification,haemorrhage in all dead pigs' lung,are the features of anatomy.In some areas,the death rate is up to 50%.Accordingly,it bring about large losses for our breed economy.It takes one year on swine high fever syndrome,the major study on clinical diagnosis,pathology dissect,bacterium isolation and purification,biochemistry identification,drug sensitivity and PRRSV isolation and identification,the result we can got:PRRSV is major cause of swine high fever without confirmed pathogency in china,although there were different feathure in our labortary with some diseaseprevalence areas in south china.E.coli,high air temperature and high humidity were inducement in the disease.We also can got:the swine high fever syndrome(SHFS) is caused by mutated viral strains of porcine reproductive and respiratory syndrome,also know as blue ear disease,and is often complicated by porcine circovirus type 2(PCV-2).The complication evolves in three stages.First,the viral infection damages pigs' immune system resulting in immunity paralysis or complete loss of immunity. Consequently,primary mixed infections usually follow including many other viral diseases such as hog cholera,pseudorabies,cephalitis B,parvovirus,rotavirus and influenza.Further, complicated viral infections lead to secondary mixed infections caused by highly contagious bacterial diseases such as streptococcemia,pleuropneumonia,colibacillosis,pasteurellosis and mycoplasma pneumonia.As a direct result of blue ear disease,SHFS often results in rapid infection and extremely high mortality rates.By the epidemiology to Investigate the information of the diseases,we can got the cause of the epidemic, Understand characteristic,symptom and pathological changes,this is in favour of laboratory diagnosis.The result of our laboratory diagnosis is anastomosis with scene symptom.To formulate the composite control schedule and to study and research effective drug is important responsibility in Current.The first aid kit is the most substaintial product for cure the swine high fever syndrome.Nonage,synthetic treat and dialectical cure is apparente for swine high fever syndrome.It can reduce the loss and impact for our society.
