PCR amplification of the region between folP and asmA in Neisseriae. A 1293 base pair product denotes the presence of aroX between folP and asmA. M: molecular marker; a: Neisseria meningitidis (Nm) strain 952 (Su^S); b: Nm 1014 (Su^S); c: Nm BT054 (Su^S); d: Nm 418 (Su^R); e: Nm 3976 (Su^R); f: Nm BT227 (Su^R); g: Nm MO035 (Su^R); h: Nm MO124 (Su^R); i: Neisseria lactamica (Su^S); j: Neisseria cinerea (Su^S). Su^S = sulfonamide-susceptible, Su^R = sulfonamide-resistant.
