Veterinary diagnostic labs (VDLs) are important service agencies providing essential diagnostic testing for a wide variety of domestic animal species as well as wildlife. They serve key roles in disease monitoring and diagnosis as well as surveillance for diseases of consequence. Of the many roles VDLs serve, one is being a member of the larger team of professionals dealing with the management of the bovine respiratory disease (BRD) complex. VDLs provide a number of services related to the management of BRD. These include disease outbreak investigation, abnormal morbidity characterization, routine monitoring, and biosecurity screening for a variety of infectious agents via methods such as necropsy and histopathology, bacterial culture, antimicrobial sensitivity testing, virus isolation, and serological assays. VDLs continue to look for better methods and assays as instrumentation technology also grows and improves. This is reflected in the growing proliferation of molecular-based assays that provide a high degree of sensitivity and specificity. Professional staff in VDLs work in collaboration with those in academia and private industry to conduct basic research focusing on a different aspect of the BRD complex. VDLs remain a primary source of the varied field-origin infectious agents associated with BRD that are used for research purposes.

兽医诊断实验室在 BRD 管理中的作用

兽医诊断实验室 (VDL) 是重要的服务机构，可为各种家畜和野生动物提供必要的诊断测试。它们在疾病监测和诊断以及对后果疾病的监测中发挥关键作用。在 VDL 所服务的众多角色中，一个是处理牛呼吸道疾病 (BRD) 复合体管理的更大的专业团队的成员。VDL 提供许多与 BRD 管理相关的服务。这些包括疾病暴发调查、异常发病率表征、常规监测以及通过尸检和组织病理学、细菌培养、抗菌素敏感性测试、病毒分离和血清学检测等方法对各种传染性病原体进行生物安全筛查。随着仪器技术的发展和改进，VDL 继续寻找更好的方法和检测方法。这反映在提供高度敏感性和特异性的基于分子的检测的日益普及上。VDL 的专业人员与学术界和私营企业的人员合作，开展基础研究，重点关注 BRD 综合体的不同方面。VDL 仍然是用于研究目的的与 BRD 相关的各种现场来源感染因子的主要来源。VDL 的专业人员与学术界和私营企业的人员合作，开展基础研究，重点关注 BRD 综合体的不同方面。VDL 仍然是用于研究目的的与 BRD 相关的各种现场来源感染因子的主要来源。VDL 的专业人员与学术界和私营企业的人员合作，开展基础研究，重点关注 BRD 综合体的不同方面。VDL 仍然是用于研究目的的与 BRD 相关的各种现场来源感染因子的主要来源。
