Table 2. Association of wcbK homopolymeric G tract with serum resistance in the ST677CC lineage.

No. of G’s	No. of blood strains	No. of faecal strains*	Avg. serum resistance (%)	p-value
8**	0	1	62
10**	12	9
9***	19	13	33.5	<0.01†

^*For one faecal strain serum resistance was not performed.

^**wcbK gene ORF truncated.

^***wcbK gene ORF intact.

^†Student’s t-test (intact wcbK ORF with 9 G’s vs truncated wcbK ORF with 8 or 10 G’s).
