col·i·cin

(kol'i-sin),
Bacteriocin produced by strains of Escherichia coli and by other enterobacteria (Shigella and Salmonella) that carry the necessary plasmids. Many are toxic to related bacterial strains and bind to specific cellular receptors interfering with normal function.
[(Escherichia) coli + bacteriocin]

colicin

/col·i·cin/ (kol´ĭ-sin) a protein secreted by colicinogenic strains of Escherichia coli and other enteric bacteria; lethal to related, sensitive bacteria.

colicin
