Antibiotics by class Generic name Brand names Common uses [4] Possible side effects [4] Mechanism of action Aminoglycosides; Amikacin: Amikin: Infections caused by Gram-negative bacteria, such as Escherichia coli and Klebsiella particularly Pseudomonas aeruginosa. Effective against aerobic bacteria (not obligate/facultative anaerobes) and ...
The bacteriocins from E. coli are called colicins (formerly called 'colicines', meaning 'coli killers'). These are the longest studied bacteriocins. They are a diverse group of bacteriocins and do not include all the bacteriocins produced by E. coli. In fact, one of the oldest known so-called colicins was called colicin V and is now known as ...
Colistin, also known as polymyxin E, is an antibiotic medication used as a last-resort treatment for multidrug-resistant Gram-negative infections including pneumonia. [ 7 ] [ 8 ] These may involve bacteria such as Pseudomonas aeruginosa , Klebsiella pneumoniae , or Acinetobacter . [ 9 ]
Antibiotic-resistant E. coli may also pass on the genes responsible for antibiotic resistance to other species of bacteria, such as Staphylococcus aureus, through a process called horizontal gene transfer. E. coli bacteria often carry multiple drug resistance plasmids, and
In clinical medicine, antibiotics are most frequently prescribed on the basis of a person's symptoms and medical guidelines.This method of antibiotic selection is called empiric therapy, [1] and it is based on knowledge about what bacteria cause an infection, and to what antibiotics bacteria may be sensitive or resistant.

A colicin is a type of bacteriocin produced by and toxic to some strains of Escherichia coli. [1] Colicins are released into the environment to reduce competition from other bacterial strains.
Escherichia coli bacteria on the right are sensitive to two beta-lactam antibiotics, and do not grow in the semi-circular regions surrounding antibiotics. E. coli bacteria on the left are resistant to beta-lactam antibiotics, and grow next to one antibiotic (bottom) and are less inhibited by another antibiotic (top).
Mecillinam or amdinocillin is an extended-spectrum penicillin antibiotic of the amidinopenicillin class that binds specifically to penicillin binding protein 2 (PBP2), [2] and is only considered to be active against Gram-negative bacteria.
