Several scientific reports describe these atypical strains associated with food poisoning and carrying non-classical enterotoxin genes: seh [24], one or more of the seg, seh, or sei genes [25,26,27], selj, ser, ses, and set [11] and, more recently, the enterotoxin gene cluster (egc) including a group of superantigens (seg, sei, sem, sen, seo in addition or not to sel and selu genes) assembled into operon-like clusters [28,29,30]. The gene discussed is EPHX2; the disease is poisoning.
