TABLE 1.

Inducible expression of SBR^a or SBR-CTA2/B^b in serovar Typhimurium clones

Clone	Protein amt (μg/1010 cells) with growth temp (°C) and conditione
	30		37
	Anaerobic	Aerobic	Anaerobic	Aerobic
pSBRnirBc	11.3	1.15	22.7	2.39
pSBR-CTA2/BnirBc	39.8	2.24	25.9	0.25
pSBR-CTA2/BnirBd	30.1	0.01	23.9	4.14

^aDetected with a sandwich ELISA using plates coated with rabbit IgG anti-SBR and developed with rabbit IgG anti-SBR–HRP. 

^bDetected with G_M1 ELISA. G_M1 ganglioside was used for coating, and rabbit IgG anti-SBR–HRP was used for detection. 

^cCultures were grown with antibiotic selection. 

^dCultures were grown without antibiotic selection. 

^eData are the means of duplicate determinations.
