The aim was to identify codon usage bias between the newly comfirmed Salmonella pullorum outer membrane protein C (ompC) gene (GenBank accession No.CP003047) and that of other 21 reference Enterobacteriaceae,and we performed comparative analysis of the codon usage bias among different organisms by a series of bioinformatics softwares The apparent codon usage bias in the 22 ompC were indicated by the codon adaptation index (CAI),effective number of codons (ENc)and the value of G+C content at the 3rd codon position(GC3s).The Enc-plot revealed that these outer membrane protein C genes are subject to GC compositional constraints.The correlation analysis with other four organisms implied that codon usage pattern of E.coli is similar to Salmonella pullorum OmpC.
