Comparison of extracellular enzymes of Fusobacterium necrophorum subsp. necrophorum and Fusobacterium necrophorum subsp. funduliforme.

摘要

A total of 10 strains each of Fusobacterium necrophorum subsp. necrophorum and Fusobacterium necrophorum subsp. funduliforme were tested for the production of 13 extracellular enzymes. DNase, alkaline phosphatase, and lipase were predominantly associated with all the strains of F. necrophorum subsp. necrophorum, with DNase not detected in any of the strains of F. necrophorum subsp. funduliforme. In addition, the strains of F. necrophorum subsp. necrophorum were generally more hemolytic than those of F. necrophorum subsp. funduliforme. Lecithinase, beta-lactamase, elastase, hyaluronidase, chondroitin sulfatase, and coagulase were not detected in any of the strains. DNase may be used to differentiate between the two subspecies.
