Usage Chloramphenicol is unusual nitroaromatic metabolite produced by Streptomyces venezuelae, first published in 1947. Chloramphenicol is a broad spectrum antibiotic with good activity against Gram negative and anaerobic bacteria. Although restricted to ocular use, antibiotic resistance to other classes has refocused attention on this class. Chloramphenicol acts by binding to the 23S sub-unit of the 50S ribosome, inhibiting protein synthesis. Chloramphenicol has been extensively studied with over 35,000 literature citations.
Usage Broad spectrum antibiotic obtained from cultures of the soil bacterium Streptomyces venezuelae. It has a broad spectrum of activity against Gram-positive and gram-negative bacteria. Antibacterial; antirickettsial
