Conclusion
The isolation ofS. necrophorus from 84 of 100 bovine livers strongly suggests that it is the principal bacterial agent responsible for bovine liver abscesses in the Sudan.
Pure cultures of the organism were isolated from 57 per cent of the abscesses compared with the range of 67 to 85 per cent recorded by Simon and Stovell (1971) and Newsom (1938).
The difference between the results obtained in this study and previous ones elsewhere is the lack of variety of organisms isolated from bovine liver abscesses. Madin (1949) and Simon and Stovell (1971) found a wide spectrum of organisms, including members of the generaEscherichia, Corynebacterium, Staphylococcus, Streptococcus and others, present in association withS. necrophorus in 30 per cent of the bovine liver abscesses examined. In this study only in 26 per cent of the abscesses were there associated organisms and these were coagulase-negative staphylococci and diphtheroids.
