On the single examination of 6804 quarter milk samples during a routine mastitis survey in 17 herds it was found that whereas 12,4% of quarters were diagnosed as subclinically mastitic when using the IDF standard set of diagnostic criteria, only 2,4% were positive when applying the additional criterium of a positive test for bovine serum albumin. The remaining 10% of quarters were then classified as being affected with septic inflammation of the ducts. The ratio of true subclinical septic mastitis to duct and test canal infections is recorded and the implications of the findings are briefly discussed.
在对17个牛群进行常规乳腺炎调查期间，对6804份季度乳样进行单次检测时发现，当使用国际乳品联合会（IDF）的标准诊断标准集时，12.4%的乳腺被诊断为亚临床乳腺炎，而在应用牛血清白蛋白检测呈阳性这一附加标准时，只有2.4%呈阳性。其余10%的乳腺随后被归类为患有导管败血性炎症。记录了真正的亚临床败血性乳腺炎与导管及检测通道感染的比例，并简要讨论了研究结果的意义。
