Table 2.

Identification and frequency of B. animalis subsp. lactis strain‐specific SNPs in the commercial VSL#3 product.

SNP a		BI04	Bi07 b	BL03		Bl04 b		Number of. reads
6 (A)		Yes	Yes	Yes		Yes		88
8 (G)		No	No	Yes		Yes		17
8 (del)		Yes	Yes	No		No		43
44 (C)		Yes	Yes	No		No		37
44 (del)		No	No	Yes		Yes		12
	BI04						73.6 %
	BL03						26.4 %

a. SNP number designations are according to Milani et al. (2013).

b. B. animalis subsp. lactis reference strains (Milani et al., 2013). Percentage of strain BI04 or BL03 = (number of reads specific for strain BI04 or BL03 x 100)/(number of reads specific for strain BI04 + number of reads specific for strain BL03).
