WebTetracyclines bind irreversibly to the 30S ribosomal subunit, but unlike aminoglycosides are bacteriostatic agents. Widespread resistance limits their utility in the hospital setting (with two exceptions), but they are still prescribed as oral agents. Short-acting oral tetracyclines include oxytetracycline and tetracycline HCl. WebGentamicin, which is an aminoglycoside antibiotic, acts by irreversibly binding to the 30s subunit of the bacterial ribosome and interfering with protein synthesis [45]. Thus, the bacterial...
