The bacterial ribosome (and eukaryotic mitochondrial ribosome) is more sensitive, but protein synthesis is also decreased in patients receiving the drug as the concentration rises. Chloramphenicol is a broad-spectrum antibiotic that interferes with mitochondrial protein synthesis and is active against a variety of organisms including salmonelloses not responsive to ampicillin. Other side effects are allergic responses or neurotoxic reactions. V. Erofeev, P. M. Kochergin, U. M. Azizov, K. Kh.
