Effects of a .18% iodophor teat dip and a fatty acid plus lactic acid teat dip on teat canal infections were studied in two separate trials under experimental challenge procedures using Staphylococcus aureus and Streptococcus agalactiae. The iodophor teat dip was 90% effective in preventing new S. aureus teat canal infections and 95.6% effective in reducing progression of S. aureus teat canal infections to intramammary infections. The dip also reduced persistence of S. aureus teat canal colonizations from week to week by 94.4%. The fatty acid plus lactic acid dip had no effect on preventing S. aureus teat canal infections but reduced progression of S. aureus teat canal infections to intramammary infections by 43.8%. The fatty acid plus lactic acid dip also reduced the persistence of S. aureus teat canal infections by 39%. An insufficient number of Strep. agalactiae teat canal infections was detected in both trials for valid analyses. Neither dip had any effect on prevalence of naturally occurring, coagulase-negative staphylococcal teat canal infections or on teat canal infections by other organisms.
在两项独立试验中，采用金黄色葡萄球菌和无乳链球菌的实验性攻毒程序，研究了0.18%碘伏乳头浸液以及脂肪酸加乳酸乳头浸液对乳头管感染的影响。碘伏乳头浸液预防新的金黄色葡萄球菌乳头管感染的有效率为90%，将金黄色葡萄球菌乳头管感染发展为乳房内感染的有效率为95.6%。该浸液还使金黄色葡萄球菌乳头管定植每周的持续率降低了94.4%。脂肪酸加乳酸浸液对预防金黄色葡萄球菌乳头管感染没有效果，但将金黄色葡萄球菌乳头管感染发展为乳房内感染的比例降低了43.8%。脂肪酸加乳酸浸液还使金黄色葡萄球菌乳头管感染的持续率降低了39%。在两项试验中检测到的无乳链球菌乳头管感染数量均不足，无法进行有效分析。两种浸液对自然发生的凝固酶阴性葡萄球菌乳头管感染的患病率或其他微生物引起的乳头管感染均无影响。
