Aminoglycoside Resistance in Gram-negative Bacilli

Korean Journal of Clinical Microbiology, 2009
Aminoglycosides are one of the clinically relevant antibiotics. They kill bacteria by binding to bacterial 30S subunit of ribosome. Resistance to aminoglycosides occurs by three different mechanisms: 1. Production of an enzyme that modifies aminoglycosides, 2.

Chemical Composition and Synergistic Antimicrobial Effects of Essential Oils From Four Commonly Used Satureja Species in Combination With Two Conventional Antibiotics

Chemistry &Biodiversity, EarlyView.
The chemical composition and the in vitro synergistic antimicrobial effects of four Satureja essential oils were investigated. Essential oils from Satureja montana and S. hortensis displayed strong antimicrobial effects, whereas S. calamintha and S. alpina exhibited relatively weaker antimicrobial activity.

Phytochemical Investigation and Biological Evaluation of Disynaphia filifolia: A Novel Source of Tremetone in Asteraceae

Chemistry &Biodiversity, EarlyView.
ABSTRACT Chemical investigation of Disynaphia filifolia (Hassl.) R.M. King & H. Rob. (Asteraceae) led to the isolation of eight compounds, with tremetone being the major metabolite recovered. Tremetone has been suggested as the toxic compound in Ageratina altissima and Isocoma pluriflora, two species of the Asteraceae family. Although D.
