| 中文摘要: |
| 为了解猪在流行性出血热(EHF)疫区的流行病学意义, 探讨猪的感染与人群发病的关系, 采用病原学、血清学和PCR技术对猪感染EHF病毒(EHFV)进行流行病学调查与实验研究。结果:猪不仅存在自然感染。而对EHFV敏感, 随血液行播及多种脏器组织, 在体内增殖并随排泄物排出感染性病毒。作者认为猪具备作为EHF传染源的条件。 |
| 英文摘要: |
| In order to study the roles of pigs with epidemic haemorrhagie fever virus, epidemiologic and experimental studies were carried out in pigs. Aetiological, serological and polymerase chain reation (PCR) techniques were performed. Resultes showed that not only pigs could be infected with EHFV under natural or experimental conditions but susceptible to EHFV as well. Virus may disseminate to many organs of the animals through blood and cause transient pathologic changes. EHFV duplicates inside tbe animal bodies and be excreted to cause pollution of environment. It is possible that pigs serve as sources of EHF infection. Our research data aiso showed for the first time that EHFV were vertically transmitted through the placenta of pigs. There was no evidence showing that people raising pigs were symptomatically sick due to EHF infection. |
