Chloramphenicol target bacteria

WebChloramphenicol, produced by Streptomyces venezuelae, was discovered in 1947; in 1949, it became the first broad-spectrum antibiotic that was approved by the FDA. … WebTherefore, chloramphenicol has a high degree of specificity towards bacterial ribosomes and does not target eukaryotic ribosomes. The significance of the difference in target specificity between prokaryotic and eukaryotic species is that it allows chloramphenicol to selectively inhibit bacterial protein synthesis without affecting eukaryotic cells.
