SLC9C1 and Diarrhea: Diarrhea is caused by different enterotoxins, including non-hemolytic enterotoxin (Nhe; Ehling-Schulz et al., 2006), hemolysin BL (Hbl; Ehling-Schulz et al., 2006), and cytotoxin K (CytK; Fagerlund et al., 2004), and emesis is due to a thermo- and acidic-stable non-ribosomal peptide, cereulide, which is encoded by the ces gene cluster (Ehling-Schulz et al., 2005; Ehlingschulz et al., 2015).
