Two germicides, one containing 0.5% chlorhexidine and one containing 1% iodine, were tested for efficacy against new intramammary infections (IMI) caused by Staphylococcus aureus and Streptococcus agalactiae. The model for the experimental challenge in the trials that were designed to test the efficacy of the two postmilking teat dips was recommended by the National Mastitis Council. The 0.5% chlorhexidine product reduced the number of new IMI caused by Staph. aureus by 73.2% and reduced the number of new IMI caused by Strep. agalactiae by 53.9%. The 1% iodine product reduced the number of new IMI caused by Staph. aureus by 75.6% and reduced the number of new IMI caused by Strep. agalactiae by 53.5%. In both trials, the incidence of clinical mastitis was also reduced in dipped quarters compared with control quarters. Use of the two teat dips over the trial periods had no effect on the condition of teat skin or teat ends.
对两种杀菌剂进行了测试，一种含0.5%洗必泰，另一种含1%碘，以检测其对由金黄色葡萄球菌和无乳链球菌引起的新的乳房内感染（IMI）的疗效。旨在测试这两种挤奶后乳头药浴液疗效的试验中的实验性攻毒模型是由美国国家乳腺炎委员会推荐的。含0.5%洗必泰的产品使由金黄色葡萄球菌引起的新IMI数量减少了73.2%，使由无乳链球菌引起的新IMI数量减少了53.9%。含1%碘的产品使由金黄色葡萄球菌引起的新IMI数量减少了75.6%，使由无乳链球菌引起的新IMI数量减少了53.5%。在两项试验中，与对照乳腺相比，药浴处理的乳腺临床乳腺炎发病率也有所降低。在试验期间使用这两种乳头药浴液对乳头皮肤或乳头末端状况没有影响。
