| 摘 要： | 从一头孕猪体内及其所产全部乳猪均检出流行性出血热（ＥＨＦ）病毒抗原。孕猪分娩有死胎，且乳猪多在产后１周发病死亡，临床表现为食欲不振、烦躁不安、喜卧、行动缓慢。用ＥＨＦ病毒抗原阳性标本接种乳鼠，可检出特异性荧光物质。该孕猪感染发生在１０月，以发病季节可基本排除乙脑感染。血清学和流行病学调查结果表明，乳猪全部感染与发病均在ＥＨＦ最短潜伏期内；可排除水平传播的可能，故推测此孕猪系怀孕后期自然感染ＥＨＦ病毒后，经胎盘传播而导致乳猪感染发病。

| Abstract: | Hantaan virus antigen was detected in a pregnant pig as well as the sucking-pigs, and most of the sucking-pigs died of illness with in a week. Clinical manifestation were consistent with the characteristics of EHF. Sucking-mice inoculated with suspension of the antigen-positive sucking-pigs lung organs.After 10 days, Hantaan virus antigen was detected in the sucking-mice brain. It was shown for the first time that Hantaan virus was transmitted vertically,possibly through the placenta of pig and located in some viscera of sucking-pigs. |
