Aminoglycosides are a family of molecules based on a 2-deoxystreptamine ring that is functionalized with a variety of sugar units that contain vicinal amine and hydroxyl functionality. These positively-charged amines promote selective high affinity binding to bacterial 16 s rRNA with resultant antibacterial activity. Aminoglycosides have also been shown to selectively target a variety of therap...
Introduction Spectinomycin is a broad-spectrum aminocyclitol antibiotic used to treat bacterial infections in human and animals. Spectinomycin is isolated from the fermentation broth of Streptomyces spectabilis, and it could contain a number of biosynthetically related components including (4S)-dihydrospectinomycin, (4R)-dihydrospectinomycin, dihydroxyspectinomycin, and some degradation product...
Background: Plasmid mediated quinolone resistance (PMQR) has been shown to play an important role in resistance not only to quinolones, but also β-lactams and aminoglycosides. In fact, qnr genes are frequently carried along with β-lactamase determinants on the same plasmids. We studied the prevalence of qnrA, qnrB, qnrS and aac(6’)-Ib-cr genes among quinolone and cephalosporin resistant clinica...
Background and Objective: Efflux pump inhibitors (EPIs) can block efflux pumps and are helpful in potentiating the activity of aminoglycosides against Pseudomonas aeruginosa. The present study compared the effects of phenylalanine-arginine beta naphthylamide (PAβN) and curcumin on aminoglycoside minimum inhibitory concentration (MIC) on Pseudomonas aeruginosa clinical isolates. Materials and M...
Background and purpose: Aminoglycosides are broad-spectrum antibiotics that are often used in combination with other antibiotics for the treatment of severe S. aureus infections. This research aimed at investigating the phenotypic and genotypic evaluation of aminoglycoside resistance in clinical isolates of MRSA in Kerman, Iran. Materials and methods: During a one...
