Abstract

In the period from 1972 to 1974, veterinary institutes in Slovakia performed bacteriological examinations in 178,853 milk samples coming from 72,454 dairy cows. On an annual average, the number of examined samples were higher by 61% than in 1967-1971. Germs responsible for the inflammation of the mammary gland were found in the milk of 22.32% of the dairy cows. The following bacterial germs were represented: Streptococcus agalactiae -- 15.77%, Staphylococcus aureus -- 4.19%, other streptococci -- 1.49%, E. coli -- 0.18%, Klebsiella sp. -- 0.23%, Corynebacterium pyogenes -- 0.20%, other germs -- 0.26%. The number of dairy cows having bacterial germs in their milk was found higher by 1.47% than in 1967-1971. The number of the findings of Streptococcus agalactiae was higher by 3.29% and that of Staphylococcus aureus by 1.15% than in the period from 1967 to 1971. The higher number of the findings of the bacterial causative agents responsible for mastitis was due, in particular, to the increased number of the findings of Streptococcus agalactiae in milk.

摘要

1972年至1974年期间，斯洛伐克的兽医机构对来自72454头奶牛的178853份牛奶样本进行了细菌学检查。年均检查样本数量比1967年至1971年期间高出61%。在22.32%的奶牛乳汁中发现了导致乳腺炎的细菌。其中检出的细菌种类如下：无乳链球菌——15.77%，金黄色葡萄球菌——4.19%，其他链球菌——1.49%，大肠杆菌——0.18%，克雷伯菌属——0.23%，化脓性棒状杆菌——0.20%，其他细菌——0.26%。发现乳汁中含有细菌的奶牛数量比1967年至1971年期间高出1.47%。无乳链球菌的检出数量比1967年至1971年期间高出3.29%，金黄色葡萄球菌的检出数量高出1.15%。导致乳腺炎的细菌病原体检出数量增加，尤其是因为牛奶中无乳链球菌的检出数量增加。
