摘　　要：2018年3月,山东省青岛市某规模化猪场暴发疫情,每天死亡100余头仔猪。70~80日龄仔猪临床表现为发热、喘气、关节肿大,30~40日龄发病仔猪主要表现为水样腹泻。为确诊引起此次疫情的病原,分析病例发病情况,结合临床症状、病理剖检和实验室诊断,最终判定为猪繁殖与呼吸综合征病毒、猪圆环病毒2型及猪流行性腹泻病毒的混合感染,且疑似存在猪链球菌和支气管败血波氏杆菌的混合感染。鉴于猪群存在多种病毒和细菌的混合感染,需要采取科学有效的综合防控措施,定期监测猪群疫病的抗体水平,及时调整免疫程序,防止疫病暴发。In March 2018,an outbreak occurred in a scaled swine farm in Qingdao City of Shandong Province,with more than 100 piglets dying per day. The piglets of 70 to 80 days old showed fever,gasping and swollen joints,and the piglets of 30 to 40 days old mainly showed watery diarrhea. In order to confirm the pathogens and analyze the outbreak,the pathological autopsy,clinical and laboratory diagnosis were carried out,and the outbreak was finally confirmed as the mixed infection of Porcine reproductive and respiratory syndrome virus（PRRSV）,Porcine circovirus type 2（PCV2）and Porcine epidemic diarrhea coronavirus（PEDV）. In addition,these piglets were also suspected of being infected with Streptococcus suis and Bronchial sepsis. In view of the mixed infection of multiple viruses and bacteria,some countermeasures should be implemented,such as adopting scientific,effective and comprehensive prevention and control measures,regularly monitoring the antibody level of pig groups,timely adjusting the immune procedure,so as to prevent disease outbreaks.
