TABLE 1.

Comparative sensitivity of culture to the BD MAX EBP assay

Isolate type (from prepared stool samples)	Sensitivity (%) by organism concentration and measurement method
	107 CFU/ml		106 CFU/ml		105 CFU/ml		104 CFU/ml		103 CFU/ml
	BD MAX	Culture	BD MAX	Culture	BD MAX	Culture	BD MAX	Culture	BD MAX	Culture
Campylobactera	NAb	NAb	100	100	100	100	100	63.8	100	43.8
EHEC (O157)c	100	100	100	75	100	75	87.5	12.5	13.3	0
Salmonellad	100	100	100	100	100	81.3	68.8	31.3	43.8	0
Shigellad	100	100	100	100	100	75	100	38	81	25

^aAt 10² CFU/ml, BD MAX had a 68.8% sensitivity and culture had an 18.8% sensitivity.

^bNA, testing not performed at this concentration.

^cOne of 16 samples testing “indeterminate” by BD MAX.

^dStool culture interpreted as positive when pathogen isolated from either HE or XLD.
