在羊圈中放置1小时后，一组23只成年美利奴羊（羊群B）意外传播了毒性绵羊蹄病，同一天早些时候，另一个羊群（羊群A）的蹄病患病率< 1%，羊群B中的绵羊通过放牧600 mm高的以雀稗为主的未改良牧场而对毒性蹄癣易感（雀稗）和袋鼠草（Themeda australis）在温暖，潮湿和潮湿的天气。除了水分，由牧场引起的趾间擦伤可能使趾间皮肤易于感染结节性叉指线虫。
Virulent ovine footrot was transmitted accidentally to a group of 23 adult Merino sheep (flock B) after holding for 1 hour in sheep yards, which earlier the same day had contained another flock (flock A) with < 1% prevalence of sheep with footrot lesions, Sheep in flock B were rendered susceptible to virulent footrot by grazing 600 mm high unimproved pasture dominated by paspalum (Paspalum dilatatum) and kangaroo grass (Themeda australis) during warm, humid and wet weather. In addition to moisture, interdigital abrasions caused by the pasture might have predisposed the interdigital skin to infection with Dichelobacter nodosus.
