Enzymes lytic against Pseudomonas aeruginosa produced by Bacillus subtillis YT-25. II. Lytic action of B-enzyme on Pseudomonas aeruginosa.

3"-phosphoryldihydrostreptomycin produced by the inactivating enzyme of Pseudomonas aeruginosa.

Escherichia coli carrying R factor was reported by Umezawaet al.l\ and Takasawa et al.2) to produce an enzyme adenylylating streptomycin, and E. colt carrying another R factor was reported by Ozanne et al.3) to produce an enzyme phosphorylating streptomycin. Though a resistant Pseudomonas was also observed by Doi et al.^ to produce an enzymeinactivating streptomycin in the presence of both ATPa...

Investigating the Effect of Lytic Bacteriophages on Pseudomonas Aeruginosa Isolates with Multidrug Resistance (MDR) in Tehran in 2021

Introduction: Pseudomonas aeruginosa bacterium has a high resistance to most anti-Pseudomonas drugs, which has caused concern all over the world. Therefore, the effect of lytic bacteriophages on Pseudomonas aeruginosa isolates with multi-drug resistance is investigated in this research. Methods and Materials: Different strains of Pseudomonas aeruginosa bacterium were identified and isolated fr...

Antibacterial Activity of Silver Nanoparticles Produced by Plantago Ovata Seed Extract Against Pseudomonas Aeruginosa

Objective: Development of resistance against many of the commonly used antibiotics is an impetus for further efforts to search for new antimicrobial agents. The aim of the study was determined as antibacterial activity of silver nanoparticles produced by Plantago ovata seed extract against Pseudomonas aeruginosa. Methods: All 30 strains of P. aeruginosa wereisolated f...

Pharmacodynamics of polymyxin B against Pseudomonas aeruginosa.

Despite limited data, polymyxin B (PB) is increasingly used clinically as the last therapeutic option for multidrug-resistant (MDR) gram-negative bacterial infections. We examined the in vitro pharmacodynamics of PB against four strains of Pseudomonas aeruginosa. Clonal relatedness of the strains was assessed by random amplification of polymorphic DNA. Time-kill studies over 24 h were performed...
