2006年1月至6月，54头乳猪送入首尔国立大学兽医学院病毒学实验室。所有猪都出现了呼吸体征、肠道体征、神经系统体征等症状，54头猪中有24头(44.4%)经反转录-套式聚合酶链式反应检测出猪血凝性脑脊髓炎病毒。根据这一结果，HEV感染似乎在韩国养猪场中流行和广泛，感染与呼吸道体征和神经系统体征比肠道体征更相关。出现呼吸道症状的HEV阳性猪被PRRSV和PCV2等病毒或巴氏杆菌等细菌混合感染。单一感染可能对乳猪其他呼吸道病原体的暴发产生亚临床影响。
From January to June 2006, 54 suckling pigs had been submitted in virology lab., College of Veterinary Medicine, Seoul National University. All pigs had suffered from various symptoms such as respiratory sign, enteric signs, neurologic signs, etc. Among 54 pigs, 24 pigs (44.4%) were positive for porcine hemagglutinating encephalomyelitis virus (HEV) through reverse transcription-nested polymerase chain reaction. According to this result, HEV infections seemed to be prevalent and widespread in Korean swine farms, and the infection is associated with respiratory signs and neurologic signs more than enteric signs. The HEV positive pigs showing respiratory signs were co-infected with viruses such as PRRSV, and PCV2, or bacteria such as Pasteurella spp. The single infection may subclinically have an influence on outbreak of other respiratory pathogens in suckling pigs.
