A teat dip containing 1.94% linear dodecyl benzene sulfonic acid and 12% glycerine, an anionic detergent formulation, was evaluated in two field trials on a commercial dairy. In Trial 1, the teat dip was compared to an undipped control in a split-herd design. Incidence of infection with Streptococcus agalactiae was reduced 57.8%; infections with presumptively identified Staphylococcus aureus were not reduced. Milking machine function and milking procedures may have affected teat dip effectiveness and incidence of udder infection. Streptococcus agalactiae was eradicated prior to Trial 2 in which the detergent teat dip was compared to a 1% iodophor product of proven efficacy. Incidence of Staphylococcus aureus infection was 40.5% lower in the detergent than in the iodophor group. Taxonomic studies on Staphylococcus species indicated that presumptive microbial identification resulted in erroneous conclusions concerning efficacy of the teat dip products. Importance of speciation of staphylococcal isolates is discussed.
一种含有1.94%直链十二烷基苯磺酸和12%甘油的阴离子洗涤剂配方的乳头浸液，在一家商业奶牛场进行了两项田间试验评估。在试验1中，采用分群设计将乳头浸液与未浸液的对照组进行比较。无乳链球菌感染发生率降低了57.8%；推定鉴定为金黄色葡萄球菌的感染率未降低。挤奶机功能和挤奶程序可能影响了乳头浸液的效果和乳房感染发生率。在试验2之前根除了无乳链球菌，在试验2中，将洗涤剂乳头浸液与一种已证实有效的1%碘伏产品进行比较。洗涤剂组金黄色葡萄球菌感染发生率比碘伏组低40.5%。对葡萄球菌属的分类学研究表明，推定的微生物鉴定导致了关于乳头浸液产品功效的错误结论。讨论了葡萄球菌分离株分类的重要性。
