chloramphenicolAn antibiotic originally derived from the soil bacterium Streptomyces venezuelae . It is highly effective in many serious conditions but has some dangerous side effects which limit its use mainly to external eye infections. In view of the spread of antibiotic-resistant organisms, however, systemic chloramphenicol is again being used to treat dangerous infections. The drug is on the WHO official list. Brand names of the eye preparations are Chloromycetin, Kemicetin, Minims chloramphenicol and Sno Phenicol.

chloramphenicola BACTERIOSTATIC antibiotic produced by a species of Streptomyces that interferes with protein synthesis on the 50S subunit of the RIBOSOME of prokaryotes. Chloramphenicol inhibits the activity of the enzyme peptidyl transferase which catalyses the formation of peptide bonds between amino acids as they are added to the polypeptide chain.
