Antibodies against the nuclease of Staphylococcus aureus were demonstrated in 99 % and 60 of samples of bovine serum and milk,, respectively. The titres of S. aureus antinucleases in milk and serum of cows with S. aureus mastitis were significantly higher than those in cows with no mastitis. The prevalence rate of S. aureus mastitis in the second lactation of cows which had not suffered mastitis during the first lactation period, was examined. Cows with high antinuclease titres in the milk during the first lactation had lower prevalence rate than those with low titres. Antibodies against the nuclease of 8 streptococcal species were demonstrated in the serum samples. However, the frequency of occurrence and the levels varied. Antinucleases against S. agalactiae were, with one exception, exclusively found in samples from cows or herds with a recorded mastitis caused by this particular organism.
分别在99%的牛血清样本和60%的牛奶样本中检测到了抗金黄色葡萄球菌核酸酶的抗体。患有金黄色葡萄球菌乳腺炎的奶牛的牛奶和血清中金黄色葡萄球菌抗核酸酶的滴度显著高于未患乳腺炎的奶牛。对在第一个泌乳期未患乳腺炎的奶牛第二个泌乳期金黄色葡萄球菌乳腺炎的患病率进行了检测。第一个泌乳期牛奶中抗核酸酶滴度高的奶牛患病率低于滴度低的奶牛。在血清样本中检测到了针对8种链球菌核酸酶的抗体。然而，其出现频率和水平各不相同。除一例例外，抗无乳链球菌核酸酶仅在有该特定病原体引起的乳腺炎记录的奶牛或牛群的样本中发现。
