The immunological detection of the 5 classical SEs has helped to establish SEA as the top contributor (~80%) to SFP outbreaks (Pinchuk et al., 2010; Hennekinne et al., 2012), followed by SED, SEB, SEC, and SEE (Hu and Nakane, 2014).

It is produced by Staphylococcus aureus growing in the host's intestines. Foodborne Pathog. Toxins 7, 53595376. Regardless of the mechanism of cross-linking, characteristic for SE activity is a polyclonal activation of a large pool of CD4+ and CD8+ T cells (~20% of the total T cells) (Marrack et al., 1990; Miethke et al., 1992; Leder et al., 1998) followed by a massive release of an assortment of T helper 1 (Th1) cytokines, such as tumor necrosis factor (TNF) , interleukin 1 (IL-1), IL-2, and interferon (IFN) (Carlsson et al., 1988; Tiedemann and Fraser, 1996), all of which contribute to the SE superantigenic effect (for a detailed reviews, see Krakauer, 2013; Krakauer et al., 2016). Interestingly, a conserved stretch of 10-amino-acid peptides, located within the longest alpha-helical chain between the A and B domains of the enterotoxins, is an important structural determinant that promotes translocation (Shupp et al., 2002; Figure 2). The production of these mutations in SEs may be part of a broader strategy of S. aureus to adapt to different host species (Marr et al., 1993; Edwards et al., 1997; Johler et al., 2016).
