TABLE 1.

Four genes with SNPs

Gene (ORF)	SNP target	Strain Sakai nucleotide	Amino acid position	Codon polymorphisma	Nonsynonymous or synonymousb	Function
ECs2357	539	C	180	T c/a C	NON	Hypothetical protein
ECs2521	1060	T	354	g/t CC	NON	p-Aminobenzoate synthetase component I
ECs3881	438	T	146	A C t/c	SYN	Hydrogenase-2 small subunit
ECs4130	630	T	210	G C t/c	SYN	Sodium/pantothenate symporter

^aLowercase letters indicate positions of reference versus diagnostic amino acids in the SNP codon.

^bNON, nonsynonymous; SYN, synonymous.
