Endotoxin, a toxic substance made by certain types of bacteria, may reduce the risk of developing the allergic skin condition eczema or wheezing in children if they are exposed to it up to age 3, suggests a new study.
Endotoxin is a part of the cell wall of gram-negative bacteria, a type of bacteria that often causes disease. Endotoxin is released when the bacteria dies or is damaged.

The higher the amount of endotoxin in their homes, the less likely they were to develop either condition by age 3.
