The stability of the aminoglycosides gentamicin, tobramycin, and amikacin stored in combination with carbenicillin, piperacillin, cefotaxime, and moxalactam was evaluated at four temperatures (25, 4, -8, and -70°C) over a 3-week period. Amikacin was the most stable of the aminoglycosides and demonstrated no loss of activity when stored with either carbenicillin or piperacillin. Gentamicin and t...

severe sepsis and septic shock are major problems as the result of high rates morbidity andmortality in intensive care units (icus). in the presence of septic shock, each hour of delay inthe administration of effective antibiotics is associated with a measurable increase in mortality.aminoglycosides are effective broad-spectrum antibiotics that are commonly used in icus forthe treatment of life...

background: aminoglycoside antibiotics are widely used in medical centers, particularly to treat infections. the resistance developed against these agents is a huge concern in health care. a number of researchers have reported that hospital and municipal wastewaters are among the most important dissemination sources of these agent into the environment. some, however, do not agree with this opin...

The aminoglycosides are used clinically in combination with beta-lactam antibiotics. The combined use, however, produces an interaction and inactivation of the antibiotics. A study was designed to investigate the kinetics of the interaction in vitro. Four concentrations of aminoglycosides (5 to 20 micrograms of gentamicin and tobramycin per ml) and penicillins (100 to 600 micrograms of carbenic...

Amikacin is a bactericidal aminoglycoside. Aminoglycosides inhibit bacterial protein synthesis. The antibacterial spectrum of amikacin is the broadest of aminoglycosides. Because of its resistance to many of the aminoglycosides-inactivating enzymes, it has a special role in hospitals where gentamicin- and tobramycin-resistant microorganisms are prevalent. Amikacin is active against the majority...

Aminoglycosides are broad-spectrum antibiotics commonly used for the treatment of serious bacterial infections. Decades of clinical use have led to the widespread emergence of bacterial resistance to this family of drugs limiting their efficacy in the clinic. Here, we report the development of a methodology that utilizes aminoglycoside acetyltransferases (AACs) and unnatural acyl coenzyme A ana...
