Abstract

Since 1976, seroepidemiological surveys using radial haemolysis and isolation trials from samples collected from pigs at the abattoir showed that Brittany was an important reservoir of swine subclinical infections due to the human Influenza A viruses H3N2. Influenza A H1Sw N1Sw subclinical infections sporadically occurred from 1979 to 1981. In January 1982 an epizootic started in Finistère which spread from west to east. The H1Sw and N1Sw antigens of 28 stains isolated from 1979 to 1982 were studied with ferret and rabbit anti sera and appeared to be variants of the previous strains (1976-1967-1961-1930). A reinforced serological survey in pigs demonstrated that both Influenza A viruses H1Sw N1Sw and H3N2 simultaneously spread in herds. There is no actual prove of recent human infections by A H1Sw N1Sw virus.

摘要

自1976年以来，利用放射状溶血法进行的血清流行病学调查以及对从屠宰场采集的猪样本进行的分离试验表明，布列塔尼是人类甲型H3N2流感病毒导致猪亚临床感染的重要疫源地。1979年至1981年期间偶尔出现甲型H1Sw N1Sw亚临床感染。1982年1月，菲尼斯泰尔省爆发了一场 epizootic 疫情，疫情从西向东蔓延。对1979年至1982年分离出的28株毒株的H1Sw和N1Sw抗原，用雪貂和兔抗血清进行了研究，结果显示它们是先前毒株（1976年 - 1967年 - 1961年 - 1930年）的变种。对猪进行的强化血清学调查表明，甲型H1Sw N1Sw和H3N2流感病毒在猪群中同时传播。目前尚无实际证据表明近期人类感染了甲型H1Sw N1Sw病毒。（注：“epizootic”这个词在医学专业中一般指动物流行病，这里直接保留英文未翻译，因为不确定是否有更准确的中文术语，或者原文就是想保留英文表述特定含义。）
