The enterotoxins produced by Enterotoxigenic Escherichia coli (ETEC) are the main diarrhea-causing pathogen, and they were divided into two groups: heat-labile toxin(LT) and heat-stable toxin(ST).

Base pathogenesis of respiratory tract viral infection is phlegm-heat obstruction in the lung, so cooling and dispersing therapy can drive away stagnated exogenous pathogen.

Heat shock can increase the resistance ability of plants under stress environment, but its effects on fungal plant pathogen remain unclear.
