Abstract
During a 20 months period in 1978 and 1979 aborted, macerated and mummified fetuses as well as stillborn piglets from herds with reproductive failure were examined for evidence of infection with porcine parvovirus (PPV). A total of 602 cases were examined and evidence of infection with PPV was found in 269 (45 %). In 52 of these antibody to PPV was found. Infective PPV as well as antibody to PPV were found in 41 %, whereas infective PPV alone was found in 7 When abortions were excluded from the results a high prevalence of infection with PPV (73–90 %) was found among fetuses of all sizes with the exception of fetuses dead late in gestation or at term.
摘要
在1978年和1979年的20个月期间，对来自出现繁殖障碍猪群的流产、浸软和干尸化胎儿以及死产仔猪进行了检查，以寻找感染猪细小病毒（PPV）的证据。共检查了602例病例，其中269例（45%）发现有感染PPV的证据。在这些病例中有52例发现了抗PPV抗体。41%的病例中同时发现了感染性PPV和抗PPV抗体，而仅发现感染性PPV的病例占7%。若将流产病例排除在结果之外，则发现除妊娠晚期或足月死亡的胎儿外，所有大小的胎儿中PPV感染率都很高（73%-90%）。
