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.

We report the complete genome sequence of a penicillin-resistant subsp. isolate, AJ79, from a tonsillitis patient. The AJ79 genome consists of a chromosome (2,440,359 bp) and plasmid (9,887 bp), providing insights into the genetic basis of penicillin resistance in and its implications for treating tonsillitis.

Article Synopsis
- The study involved regular monitoring of body weights and blood samples over a period, with steers harvested at two different time points (3 and 10 days) for detailed examination of various organs for signs of disease.
- Results showed no significant differences in overall health or liver abscess development between treatments, indicating that the LPS challenge combined with specific bacterial inoculations did not effectively induce liver abscesses in the steers within the study timeframe.
