Aminoglycoside represents a class of versatile and broad spectrum antibacterial agents. In an effort to revive the antibacterial activity against aminoglycoside resistant bacteria, our laboratory has developed two new classes of aminoglycoside, pyranmycin and amphiphilic neomycin (NEOF004). The former resembles the traditional aminoglycoside, neomycin. The latter, albeit derived from neomycin, ...
The mechanisms by which quinolones rapidly kill are ill defined. We have investigated the action of ciprofloxacin on Escherichia coli KL16 with a combination of traditional and flow cytometric methods and have analyzed cells for changes in membrane potential, membrane integrity, oxidative metabolism, morphology, and viability. Log-phase cultures were exposed to various concentrations (0.1, 1, 1...
The resistance of bacteria towards traditional antibiotics currently constitutes one of the most important health care issues with serious negative impacts in practice. Overcoming this issue can be achieved by using antibacterial agents with multimode antibacterial action. Silver nano-particles (AgNPs) are one of the well-known antibacterial substances showing such multimode antibacterial actio...
Escherichia coli is among the most frequently encountered germs of purulent septic infections of various localizations. The E.coli strains tend to develop multiple resistance caused by the production of extended spectrum beta-lactamases (ESBLs) and carbapenemases. This dictates the necessity to search for new antimicrobial agents. In this respect, metal nanoparticles are promising candidates fo...
Objective. To determine the minimum inhibitory concentration of Ag nanoparticles in relation to clinical pathogenic strains microorganisms. Methods. The nanoparticles, obtained by metal vapor synthesis was studied on six bacteria, including representatives gram-positive and gram-negative groups. microbiological analyzer Vitek 2 Compact used identify each strain antibiogram. study were synthesiz...
