Abstract
The effects of Fusobacterium necrophorum subsp. necrophorum on cellular actin were investigated using tissue-cultured bovine portal cells. Fluorescence studies revealed the appearance of intense fluorescent spots on the cellular actin and the spots increased in a time dependent manner. Sodium dodecyl sulphate polyacrylamide gel electrophoresis profiles manifested partial or complete degradation of actin preparation after treatment with the bacterial cells. These findings suggest that the bacterial cell wall may contribute to the degradation of the cellular actin during the initial stage of the infection caused by F. necrophorum subsp. necrophorum.
