The level of total lactate dehydrogenase activity in dairy cow milk serum was studied in sets of quarter-udder milks showing different degrees of a positive response to Mastitis test-NK. The bacteriological examination for Streptococcus agalactiae, Streptococcus dysgalactiae, Streptococcus uberis, Staphylococcus aureus, and for coliform germs was performed at the same time. Increasing positiveness of the response to Mastitis test-NK was found to be accompanied by an almost proportionate increase of the total lactate dehydrogenase activity level in milk serum. The bacteriological finding was not correlated with increasing positiveness of the response to Mastitis test-NK. New aspects of various diseases of the mammary gland and the possibility to diagnose mainly the latent stages of these diseases are analysed in a discussion.
在对乳腺炎检测-NK呈现不同程度阳性反应的多组四分之一乳房乳汁中，研究了奶牛乳汁血清中总乳酸脱氢酶活性水平。同时对无乳链球菌、停乳链球菌、乳房链球菌、金黄色葡萄球菌和大肠菌群进行了细菌学检查。结果发现，乳腺炎检测-NK反应阳性程度的增加伴随着乳汁血清中总乳酸脱氢酶活性水平几乎成比例的升高。细菌学检查结果与乳腺炎检测-NK反应阳性程度的增加无关。在讨论中分析了乳腺各种疾病的新情况以及主要诊断这些疾病潜伏阶段的可能性。
