Abstract

Efficacy (reduction of new intramammary infections) was determined against Staphylococcus aureus in 14 trials and against Streptococcus agalactiae in 5 trials. Against Staphylococcus aureus seven 1% iodophor products had an average efficacy of 89.9% while three .5% iodophor products averaged 76.4%. A solution of sodium dichloro-s-triazenetrione reduced infections 79.0% and 2% dodecyl benzene sulfonic acid was 50.4% effective. Efficacies of two quaternary ammonium products at .18 and .5% were 84.8 and 60.9%. A placebo vehicle and .15 M saline as teat dips reduced infections 8.9 and 9.2%. Infection rates with Streptococcus agalactiae were low; efficacy ranged from 50.5 to 100.0%, average 65.6%. The model of experimental exposure provided a better estimate of effectiveness of a teat dip than would be possible under conditions of most commercial dairying.

摘要

在14项试验中测定了对金黄色葡萄球菌的疗效（减少新的乳房内感染），在5项试验中测定了对无乳链球菌的疗效。对于金黄色葡萄球菌，7种1%的碘伏产品平均疗效为89.9%，而3种0.5%的碘伏产品平均疗效为76.4%。二氯-s-三嗪三钠溶液减少感染的比例为79.0%，2%的十二烷基苯磺酸的有效率为50.4%。两种季铵盐产品浓度分别为0.18%和0.5%时，疗效分别为84.8%和60.9%。作为乳头浸泡液的安慰剂载体和0.15M盐水减少感染的比例分别为8.9%和9.2%。无乳链球菌的感染率较低；疗效范围为50.5%至100.0%，平均为65.6%。与大多数商业奶牛场的条件相比，实验性暴露模型能更好地估计乳头浸泡液的有效性。
