Obligately anaerobic bacterial species isolated from foot-rot lesions in goats.
Lesions showing clinical signs of foot-rot from 120 goats were cultured on six selective media during October 1987 to November 1988. A total of 582 strictly anaerobic microorganisms belonging to 50 different species was isolated and identified. The anaerobes most frequently isolated belonged to the following genera: Bacteroides (80%), Peptostreptococcus (63.6%), Megasphaera (40%), Fusobacterium (29.2%), Clostridium (22.5%), Propionibacterium (12.5%), Eubacterium (11.7%) and Leptotrichia (10.8%). Percentages for Acidaminococcus, Peptococcus, Tissierella, Wolinella and Veillonella were below 10%. The following species were identified in 10% or more of cases: Peptostreptococcus anaerobius (61.7%), Bacteroides buccae (51.7%), Bacteroides nodosus (42.5%), Megasphaera elsdenii (40%), Bacteroides ruminicola subsp. brevis (22.5%), Fusobacterium necrophorum (19.2%), Leptotrichia buccalis (11.7%) and Clostridium perfringens (10%). Lower percentages were obtained for the remaining species. The efficiency and selectivity of the six culture media used for isolation are discussed.
