[Experimental induction of foot rot in sheep].

By means of local strains Bacteroides nodusus was reproduced experimentally a case of foot-rot with sheep. For the appearance and the development of the disease it was necessary, before the infection, to keep the sheep in damp and uncleaned from fecal impurities room. Besides that, of decisive importance was the scarification of the skin-horny junction in the interungular slit. The combination of Bacteroides nodusus with Spirohaeta penorta and Corynebacterium piogenes resulted in more serious changes in the infected hooves.
