Venn diagram of shared and unique genes found in four Serratia genomes. The unique and shared genome among the compared genomes was determined by a dual cutoff of 30 % or greater amino acid identity and sequence length coverage of at least 70 %. Analysis was done using the MAUVE genome alignment tool [42]. SCBI: Serratia sp. SCBI; SMAR: S. marcescensDB11; SPRO: S. proteamaculans568, SAS12, Serratia sp. AS12
