用于控制乳腺炎的方法的有效性较低。因此，寻找可以提高奶牛对乳房病原体免疫力的指标。本研究的目的是确定哺乳期前三个月血液白细胞酸性磷酸酶 (AcP) 多态性、BLV 感染、体细胞计数和乳汁成分之间的关系。研究对象为 65 头 3 至 6 岁的黑白奶牛，这些奶牛来自白血病为主的牛群。通过 ELISA 和 PCR 检测诊断出地方性牛白血病。进行了以下分析：牛奶中总蛋白、乳糖、干物质、体细胞计数的含量以及微生物分析。获得的结果表明，奶牛自然感染 BLV 与乳腺分泌紊乱之间存在关联，而与酸性磷酸酶多态性的关系并不明确。所获得的结果鼓励继续研究血液白细胞 AcP 在乳腺炎发病机制中的作用。
Effectiveness of the methods applied to control mastitis is low. Therefore, indices are sought which could improve cow immunity to udder pathogens. The aim of the study was to determine the relationship between the polymorphism of blood leukocyte acid phosphatase (AcP), BLV infection, the somatic cell counts and the milk composition in the first trimester of lactation. Studies were performed oil a population of 65 Black-and-White cows, aged 3-6 years, from a leukemia-dominated herd. Enzootic bovine leukemia was diagnosed with ELISA and PCR tests. The following analyses were performed: the contents of total protein, lactose, dry matter, somatic cell count in milk as well as microbiological analyses.The obtained results indicate the occurrence of an association between a natural BLV-infection and mammary gland secretion disturbances in cows, whereas the relationship with the acid phosphatase polymorphism is not explicit. The obtained results encourage the continuation of studies into the role of blood leukocytes AcP in the pathogenesis of mastitis.
