A Salmonella lytic bacteriophage, SS3e, was isolated, and its genome was sequenced completely. This phage is able to lyse not only various Salmonella serovars but also Escherichia coli, Shigella sonnei, Enterobacter cloacae, and Serratia marcescens, indicating a broad host specificity. Genomic sequence analysis of SS3e revealed a linear double-stranded DNA sequence of 40,793 bp harboring 58 open reading frames, which is highly similar to Salmonella phages SETP13 and MB78.
