Genomic analysis of bacteriophage epsilon 34 of Salmonella enterica serovar Anatum (15+).

ABSTRACT:

Background

The presence of prophages has been an important variable in genetic exchange and divergence in most bacteria. This study reports the determination of the genomic sequence of Salmonella phage epsilon 34, a temperate bacteriophage that was important in the early study of prophages that modify their hosts' cell surface and is of a type (P22-like) that is common in Salmonella genomes.

Results

The sequence shows that epsilon 34 is a mosaically related member of the P22 branch of the lambdoid phages. Its sequence is compared with the known P22-like phages and several related but previously unanalyzed prophage sequences in reported bacterial genome sequences.

Conclusion

These comparisons indicate that there has been little if any genetic exchange within the procap
