摘　　要：近几年 ,猪放线杆菌、副猪嗜血杆菌、猪链球菌已成为严重危害规模化养猪业的重要病原菌 ,这些病菌可早期定居感染 ,通过早期断奶管理措施难以控制。由于其血清型多 ,存在交叉反应抗原 ,缺乏明显的毒力标志 ,这给血清学监测。In recent years,Actinobacillus suis,Haemophilus parasuis,and Streptococcus suis have become the important pathogens of large scale pig farms.These pathogens were early colonizers,were difficult to control by management procedure such as segregated early weaning.Vaccination,serodiagnostic testing,and even serotyping were complicated by the presence of multiple serotypes,cross reactive antigens,and the absence of clear markers for virulence.In this review,we discussed the progress on the pathogenesis,epidemiology,and management of these pathogens.
