TABLE 1.

Reactivity of T. pallidum MAb H9-2 with PROS and T. vincentii whole cells during sequential subculture in mP4, NOS, or combinations of mP4 and NOS

Treponema	Reactivity under indicated subculture conditionsa
	NOS/NOS/NOS	NOS/mP4/NOS	mP4/NOS/mP4	mP4/mP4/mP4
T. vincentii	Neg/neg/neg	Neg/neg/weak	Pos/pos/pos	Pos/pos/no growth
OMZ-802	Neg/neg/neg	Neg/neg/weak	Pos/neg/pos	Pos/pos/weak
OMZ-804	Pos/pos/no growth	Pos/pos/pos	Pos/pos/pos	Pos/pos/pos

^aNOS and mP4 were used in the order indicated. The corresponding reactivities are similarly indicated. No stained cells were detected in negative (neg) reactions. Some lightly stained cells were detected, but most cells were not stained, in weak reactions. All, or nearly all, cells were well stained in positive (pos) reactions.
