Experimental observations on prophylactic and therapeutic vaccination against foot-rot in sheep

Abstract Extract Egerton and Roberts (1971) reported that vaccines prepared from Bacteroides nodosus (Beveridge) Mraz et al. had both protective and curative effects on foot-rot induced artificially in penned sheep. Similar results were obtained in experiments on Australian properties when vaccinated sheep were exposed to natural infection (Egerton and Burrell, 1970). These findings have revived interest in the application of immunological methods to the inveterate problem of foot-rot control, an approach that had formerly been regarded as unfeasible (Beveridge, 1941).
