Table 2.

The mechanisms and characteristics of different types of SEs.

SEs	Functions
SEA	Anti-protein hydrolase, supercarcinogenic and emetic toxin, causes food poisoning, but no diarrheal activity
SEB	Increase in the number of T lymphocytes, as well as the concentration of pro-inflammatory cytokines and inflammatory mediators in the intestinal mucosa; increase mucosal permeability and intestinal secretion
SEC	Supercarcinogenic and emetic toxin, but no diarrheal activity
SEG	Reversible destruction of intestinal cell ultrastructure
SEH	Causes food poisoning
SEI	Reversibly disrupts enterocyte ultrastructure and exhibits weak emetic activity
SEM	Strong emetic potential
SEO	Has emetic activity
SEQ	Significantly stable for heat treatment and digestive enzyme degradation, and exhibits significant supercarcinogenic and emetic activity
