sigB and gap allelic-type diversity among a subset of 119 isolates used to validate a rapid method for identifying isolates of Listeria^a

Species (no. of isolates)	No. of allelic types based on:
	sigB	gap
L. marthii (1)	1	1
L. innocua (9)	8	2
L. monocytogenes (18)	3	7
L. welshimeri (20)	11	2
L. seeligeri (71)	12	8
Total (119)	35	20

^aThe method used morphology on Listeria monocytogenes plating medium (LMPM), motility at 25°C, and sigB sequencing.
