Clinical signs associated with bovine spongiform encephalopathy (BSE) were studied in 1008 casualty slaughter cattle over 30 months of age to compare the results with the BSE status as determined by postmortem tests. The clinical BSE status was assessed using seven different criteria based on various publications. Only one (0.10%) out of 997 casualty slaughter cattle with a matching postmortem test result was positive for BSE. The BSE case was identified by only two case definitions tailored specifically to recumbent cases. The variety and often equivocal definition of clinical signs associated with BSE is reflected by the difference in the criteria that usually identified different animals as BSE suspects. The BSE status may be more difficult to assess in recumbent animals that do not allow a full clinical examination, and BSE may not be suspected if another disease is present that may mask signs of BSE.
对1008头30月龄以上的屠宰病牛进行了与牛海绵状脑病（BSE）相关的临床体征研究，以便将结果与死后检测确定的BSE状况进行比较。根据各种出版物，使用七种不同标准评估临床BSE状况。在997头有匹配死后检测结果的屠宰病牛中，只有一头（0.10%）BSE呈阳性。仅通过专门针对卧地病例制定的两种病例定义确定了这例BSE病例。通常将不同动物鉴定为BSE疑似病例的标准存在差异，这反映出与BSE相关的临床体征种类繁多且定义往往不明确。对于无法进行全面临床检查的卧地动物，评估BSE状况可能更加困难，如果存在另一种可能掩盖BSE体征的疾病，则可能不会怀疑患有BSE。
