【摘要】 １９８６～１９８９年，从广西５个地、市的１０个病猪场猪体中分离到１０个病毒。用猪瘟石门系标准强毒作对照，经病原性、抗原性及血清学试验，培养特性，血细胞吸附及病毒的形态结构观察，证明１０个毒株为猪瘟病毒。它们有共同的抗原性。它们之间的区别只是毒力的强弱不同。从临床症状、病理变化和病程方面看，９个为亚急性猪瘟毒株；一个为慢性或温和性猪瘟毒株。更多还原

【Abstract】 From 1986 to 1989, 10 strains of swine fever virus isolated from the infected pigs on 10 farms of 5 prefectures or cities in Guangxi were investigated on their pathogenicity, antigenicity, morphological structure and characteristic of culture, serology and hemocyte absorption. The antigenicity is determined by comparing with the Shimen standard virulent strains of swine fever. These 10 virulent strains are identified as swine fever viruses, and have a common antigenicity. Thier differences are shown only in the virulence level. In comparision with Shimen standard virulent strains in the clinic symptom, pathological diagnosis and virulence level, 9 of them are considered as subacute swine fever strains and one as chronic or mild strain.更多还原
