Elastolytic activity was detected in all 10 Bacteroides nodosus strains isolated from the hooves of 9 affected animals. Among 14 other isolated strictly anaerobic microorganisms belonging to different species or genera only 4 strains showed a low degree of elastolysis. The 14 antimicrobial agents studied effectively inhibited "in vitro" growth of B. nodosus.enAntimicrobialMicrobiologyBacteroidesFoot rotBiologyIsolation (microbiology)Bacteriaarticle
