Extended Spectrum Beta-Lactamase Infection

(ESBL)

Definition

Extended spectrum beta-lactamases (ESBLs) are enzymes made by bacteria. They make it harder for the usual medicines to care for infections. Without them, getting sick can lead to serious health problems or death.

The Intestines

The bacteria can travel to the intestines, causing a serious infection.
