Nine postmilking teat dips were evaluated by an experimental challenge model against either Staphylococcus aureus, Streptococcus agalactiae, or both. Formulations containing .9 and .6% sodium hypochlorite, 1% sodium dichloro-s-triazene-trione, .55% chlorhexidine gluconate, and .35% povidone iodine reduced incidence of Staphylococcus aureus infections 56.8, 28.3, 75.9, 92.5, and 77.9%. Incidence of infections with Streptococcus agalactiae was reduced 48.1 and 63.2% by 1.7 and 1% sodium dichloro-s-triazene-trione formulations. The 1% chlorhexidine gluconate and .35% povidone iodine products reduced Streptococcus agalactiae infections 71.0 and 67.0%. Three experimental 1% iodophor formulations reduced Streptococcus agalactiae infections 28.9, 44.8, and 50.7%. The experimental challenge model was refined further and provided an efficient method to determine efficacy of postmilking teat dips.
通过实验性攻毒模型对九种挤奶后乳头浸液进行了评估，以对抗金黄色葡萄球菌、无乳链球菌或两者。含有0.9%和0.6%次氯酸钠、1%二氯-s-三嗪三酮钠、0.55%葡萄糖酸氯己定和0.35%聚维酮碘的制剂使金黄色葡萄球菌感染发生率分别降低了56.8%、28.3%、75.9%、92.5%和77.9%。1.7%和1%二氯-s-三嗪三酮钠制剂使无乳链球菌感染发生率分别降低了48.1%和63.2%。1%葡萄糖酸氯己定和0.35%聚维酮碘产品使无乳链球菌感染降低了71.0%和67.0%。三种实验性1%碘伏制剂使无乳链球菌感染降低了28.9%、44.8%和50.7%。实验性攻毒模型得到了进一步完善，并提供了一种测定挤奶后乳头浸液功效的有效方法。
