Role of bacterial endotoxins of intestinal origin in rat heat stress mortality.

Using unanesthetized rats, the effect on heat stress mortality of endotoxin tolerance or zymosan treatment was determined. In addition, the incidence of invasion by gram-negative bacteria and their endotoxins was studied to evaluate the role of gut-derived bacterial endotoxins after heat stress. Endotoxin tolerance resulted in heat stress resistance. The… CONTINUE READING
