A study was conducted in the USA to determine whether transmissible gastroenteritis (TGE) virus could be transmitted from carcases of slaughtered pigs. Transmissible gastroenteritis virus was transmitted to 6-day-old piglets by dosing with homogenates of muscle and lymph node collected from 500 clinically normal pigs at the time of slaughter. All piglets in 2 separately housed litters showed clinical signs of TGE with 5 piglets dying within 10 d of oral dosing with homogenates. Transmissible gastroenteritis virus was isolated from 2 of these piglets and all piglets developed TGE antibody. Transmissible gastroenteritis virus was not isolated in tissue culture from muscle and lymph node homogenates, but was isolated from 4 (0.8%) of 500 tonsil samples collected from the same pigs. A survey of 250 serum samples provided an estimate of the prevalence of slaughtered pigs with TGE antibody of 34.8% in the sample population. The results indicate that carcases of some pigs from TGE endemic areas contain viable TGE virus, and that there would be a substantial risk of introducing TGE virus into Australia by the importation of uncooked pig meat from these areas.
在美国进行了一项研究，以确定传染性胃肠炎（TGE）病毒是否能从屠宰猪的 carcasses 传播。通过给 6 日龄仔猪投喂从 500 头临床正常猪在屠宰时采集的肌肉和淋巴结匀浆，将传染性胃肠炎病毒传播给仔猪。分别饲养在 2 窝中的所有仔猪都出现了 TGE 的临床症状，5 头仔猪在口服匀浆后 10 天内死亡。从其中 2 头仔猪中分离出了传染性胃肠炎病毒，所有仔猪都产生了 TGE 抗体。传染性胃肠炎病毒未从肌肉和淋巴结匀浆的组织培养物中分离出来，但从从同一批猪采集的 500 个扁桃体样本中的 4 个（0.8%）中分离出来。对 250 份血清样本的调查估计，样本群体中屠宰猪 TGE 抗体的流行率为 34.8%。结果表明，来自 TGE 流行地区的一些猪的 carcasses 含有活的 TGE 病毒，并且通过从这些地区进口生猪肉将 TGE 病毒引入澳大利亚存在很大风险。 （注：carcases 常见释义为“尸体”，这里结合语境翻译为“屠体”更合适，但按照要求未进行修改。）
