ESBLs are enzymes that are produced by bacteria. The enzymes make the bacteria resistant to many kinds of antibiotics.
It is possible to carry these bacteria without being sick. This is called being colonized. A person who is colonized can still spread the infection to others. The bacteria that carry the enzymes can cause serious infections, such as those
in the: IntestinesUrinary tractRespiratory tract
If not treated, the condition can be fatal.
The bacteria can travel to the intestines, causing a serious infection.

This condition occurs when the body is infected with bacteria. These bacteria produce enzymes that make the infection resistant to many kinds of antibiotics. That is why it is so hard to treat.
These bacteria can be easily spread in close living areas, like hospitals. They are most often spread by: Medical equipmentThe hands of healthcare workers
Factors that increase your risk of being colonized by or infected with ESBL include: Admission to an intensive care unit (ICU)Recent surgeryA long hospital stayUse of invasive medical devices, such as a urinary catheterAntibiotic useNursing home residence
urinary tract infectionsUse of a feeding tubeHemodialysisDiabetesPoor nutrition
Symptoms depend on the location of the infection and may include: FeverPain in abdomenPain and burning with urinationSigns of infection around a wound, such as redness or oozing dischargeDiarrheaLoss of appetiteChillsNausea and vomitingTrouble breathing
Your doctor will ask about your symptoms and medical history. A physical exam will be done. Tests may include: Urine, stool, or blood testsSwab of the rectum or throat
The bacteria in the samples are then tested to see if it they are resistant to certain antibiotics.
Talk with your doctor about the best treatment plan for you. There are only a few antibiotics that can be used to treat this infection.
It is also important to take steps to control the spread of ESBL infections, such as:
Preventing the spread of ESBL-producing bacteria to others by isolation,
, and other steps
Avoiding unnecessary procedures
To help reduce your chance of getting an ESBL infection, take these steps: Wash your hands thoroughly, and ask others to wash their hands.Avoid coming into contact with people who have this infection.Making sure nurses, doctors, and visitors wash their hands before and after touching you or touching contaminated surfaces.
