They are Gram-negative bacteria that produce an enzyme, beta-lactamaze that can break down commonly used antibiotics, such as penicillin and cephalosporins, making infections with ESBL producing bacteria more difficult to treat. Enterobacteriaceae E.coli and Klebsiella pneumoniae are common producers of ESBL, and they usually cause urinary tract infections and bacteraemia.
People who carry ESBL producing bacteria without any sign or symptom of infection are “colonized”.

The main reservoir is the lower bowel of colonized or infected persons. Common ways of transmission is through unwashed hands.
ESBL producing bacteria can survive on surfaces without a major role in transmission, if good hand washing and infection control measures are practiced.
ESBL decolonization is not effective and not recommended.
The preferred specimen for ESBL screening is a rectal swab or stool. Stool specimens have a higher yield. A urine culture may also be sent in certain circumstances such as the presence of catheters.
In general, use routine practices and contact precautions (gloves and gown) when providing direct resident care.
Review at least three negative laboratory test results from all colonized or infected body sites, with specimens collected at least one week apart, in the absence of antibiotic therapy with Infection Control.
