Surveillance And Diagnosis Report On Mixed Infection Of Classical Swine Fever Virus And Porcine Circovirus Type 2

Classical Swine Fever (CSF) and post-weaning multisystemic wasting syndrome (PMWS) is seriously endangering China's major pig-raising industry in the development of the two major infectious diseases. Classical swine fever is caused by the swine fever virus, a pig with acute or chronic, fever and a high degree of contact with sexually transmitted diseases. Classical swine fever were distributed world-wide, because of its high degree of hazard, of the pig farming industry and huge economic losses, the World Health Organization (OIE) this disease will be required to report infectious diseases as one of the key provisions of international quarantine. In recent decades, many countries have taken measures to eradicate swine fever, for example, the European Union to take slaughtered pig virus, veterinary formulating laws and regulations, and environmental disinfection measures to achieve significant results. Due to our long-term extensive coverage of Hog Cholera vaccine comprehensive control measures, large-scale outbreak of the basic stop, but because of a variety of reasons, this disease still occurred in our country, is against the largest pig-raising industry, one of the most dangerous infectious diseases.PMWS by porcine circovirus type 2 (PCV-2) caused by a new disease, PCV-2 infection can cause secondary immunodeficiency, so that infected pigs are not motivated to other pathogens an effective immune response. Pig disease often caused by immunosuppression as a result of secondary infection, increased disease, so that the higher mortality rate, to the pig farming industry, causing huge economic losses. In recent years, as mainland China continues on CSFV and other pathogens reported mixed infection, but CSFV mixed with PCV-2 infection is reported frequently.In this study, combined with local pig farms on the basis of the detection of infection, testing positive for the pig farms were epidemiology, clinical symptoms, pathological autopsy studies, and the use of established methods of PCR, quickly and accurately from the positive The success of pig farms in the sample detected CSFV and PCV-2, the final work out reasonable measures to control the economy.
