牛呼吸道疾病综合征(BRDC)是一种急性呼吸道疾病,其主要细菌性病原有多杀性巴氏杆菌、溶血性曼氏杆菌、化脓隐秘杆菌和昏睡嗜血杆菌,常见于断奶、运输等应激后牛群。该病呈世界性分布,可经呼吸道感染,严重影响肉牛及泌乳牛的品质,给养牛业造成巨大的经济损失。国内关于BRDC的研究仍比较匮乏,且尚无可预防BRDC细菌性病原的疫苗,为更好地防控BRDC,现就国内外BRDC细菌性病原的致病机理和防控研究进展做一综述。
Bovine respiratory disease syndrome (BRDC) is an acute respiratory disease, the main bacterial pathogens are multi-killed Pasteurella, hemolytic Leucons, pyogenic bacteria and Haemophilus amblycephala, common in weaning, transport should be After the cattle. The disease is worldwide distribution, can be respiratory tract infection, seriously affecting the quality of beef cattle and lactating cattle, cattle industry caused huge economic losses. The domestic research on BRDC is still scarce, and there is no vaccine to prevent the bacterial pathogens of BRDC. In order to better prevent and control BRDC, the pathogenesis and prevention and control of bacterial pathogens at home and abroad are reviewed.
