摘要:

近年来牛呼吸道疾病常被报道,牛呼吸道疾病对牛业有着严重危害,牛呼吸道疾病的大肆流行会为养殖场带来不可逆转的损失。为揭示近年来宁夏回族自治区犊牛呼吸道主要病原体牛支原体(Mycoplasma bovis, M. bovis)、溶血性曼氏杆菌(Mannheimia hyopneumoniae, Mh)、多杀性巴氏杆菌(Pasteurella multocida, Pm)、肺炎克雷伯菌(Klebsiella pneumonia, K.pn)的流行情况,本研究采用形态观察结合分子生物学检测方法,对2022—2024年间采集自宁夏地区不同县/区的457份牛鼻拭子及组织样品进行了病原分离及分子生物学检测鉴定病原体。系统分析了宁夏不同年份、不同地区、不同季节、不同生长阶段肉牛感染M. bovisMhPmK.pn的情况。结果显示,Pm在四种病原体中检出率最高(38.73%),极显著高于其他三种病原体(P < 0.001);中部干旱带M. bovis检出率极显著高于引黄灌区(P < 0.01)和南部山区(P < 0.001);冬季M. bovis(50%)和K.pn(70.5%)检出率均为最高且极显著高于夏秋季(P<0.001);Pm秋季检出率最高(45.3%),极显著高于冬季(P < 0.01)和春季(P < 0.001);育成期牛Pm检出率极显著高于哺乳期和成熟期(P < 0.001);单一Pm检出率最高(16.85%),显著高于混合感染检出率(P < 0.01);Mh+Pm(7.22%)混合感染率最高。本研究从多个角度调查及分析了宁夏地区牛支原体、溶血性曼氏杆菌、多杀性巴氏杆菌和肺炎克雷伯菌的发生规律,总结不同时间、地区、生长阶段等因素对牛呼吸系统疾病检出率的影响,为宁夏地区牛呼吸道主要细菌感染防治提供了科学依据。

Abstract:

In recent years, bovine respiratory diseases have been increasingly reported, posing significant threats to the cattle industry. Large-scale outbreaks can result in substantial and often irreversible economic losses for livestock operations. This study aims to investigate the prevalence of key respiratory pathogens—Mycoplasma bovis (M. bovis), Mannheimia haemolytica (Mh), Pasteurella multocida (Pm), and Klebsiella pneumoniae (K.pn) —in calves from the Ningxia Hui Autonomous Region. A total of 457 nasal swab and tissue samples were collected from cattle across various counties and districts in Ningxia between 2022 and 2024. Pathogen identification was conducted using a combination of morphological examination and molecular diagnostic techniques. The infection rates of M. bovis, Mh, Pm, and K.pn were systematically analyzed based on year, geographic region, season, and developmental stage of the cattle. Among the four pathogens studied, Pm exhibited the highest overall detection rate (38.73%), a difference that was highly significant compared with the other three pathogens (P < 0.001). In the central arid zone, the prevalence of M. bovis was significantly greater than in both the Yellow River irrigation area (P < 0.01) and the southern mountainous region (P < 0.001). Seasonally, winter yielded peak detection rates for M. bovis (50%) and K.pn (70.5%), both of which exceeded summer and autumn rates (P < 0.001). Conversely, Pm reached its highest autumn prevalence (45.3%), significantly surpassing its winter (P < 0.01) and spring (P < 0.001) levels. During the growing phase, Pm detection was markedly higher than during both the lactation and mature phases (P < 0.001). Finally, single Pm infections were the most common (16.85%), significantly outnumbering mixed infections (P < 0.01), and the most frequent mixed co-infection occurred with Mh+Pm at 7.22%. This comprehensive epidemiological analysis delineates how temporal, geographical, seasonal, and developmental variables affect bovine respiratory pathogen prevalence in Ningxia, thereby furnishing a scientific framework to guide targeted prevention and control strategies for bacterial respiratory infections in the region.
