Kansas Agricultural Experiment Station Research Reports
DNA finger printing (restriction fragment length polymorphism analysis) was employed to genetically compare Fusobacterium necrophorum isolates of liver abscesses, ruminal wall, and ruminal contents from the same animal. Fusobacterium necrophorum isolates from liver abscesses were genetically identical to the corresponding isolates from the ruminal wall in eight of nine animals tested. This genetic similarity between the isolates supports the hypothesis that F. necrophorum in liver abscesses originates from the ruminal wall.
