Twelve of twenty-one udder quarters with colonized teat ducts became infected within 13 d when milked with a machine producing large cyclic and irregular vacuum fluctuations in the teatcup; of 23 quarters milked under the same conditions, but with metal shields fitted inside the liners to protect the teat apex (Thiel, 1974), only 2 quarters became infected in the same period. The introduction of a post-milking teat disinfectant teat dip resulted in the elimination of orifice colonization from 15 teats dipped in Na hypochlorite solution (40 g/l available chlorine) and from all but 2 of 15 teats dipped in an iodophor solution (5 g/l available iodine).
在使用奶杯产生大的周期性和不规则真空波动的机器挤奶时，21个被定植的乳腺管中有12个在13天内感染；在相同条件下挤奶，但在内衬中安装金属护罩以保护乳头顶端（蒂尔，1974年）的23个乳腺管中，同期只有2个感染。使用挤奶后乳头消毒剂乳头浸液，可消除15个浸在次氯酸钠溶液（有效氯40克/升）中的乳头的开口处定植，以及15个浸在碘伏溶液（有效碘5克/升）中的乳头中除2个以外所有乳头的开口处定植。
