Infections with multi-drug resistant E. coli, which is also known as ESBL (extended spectrum beta-lactamase), have been assumed to be a hospital phenomenon.

These bacteria produce enzymes known as E xtended S pectrum B eta-L actamases or ESBLs for short.f a patient is suspected to have an infection then a swab or or specimen of the infected area will be taken and sent to the microbiology lab for testing.
