MexXY multidrug efflux system of Pseudomonas aeruginosa
Anti-pseudomonas aminoglycosides, such as amikacin and tobramycin, are used in the treatment of Pseudomonas aeruginosa infections. However, their use is linked to the development of resistance. During the last decade, the MexXY multidrug efflux system has been comprehensively studied, and numerous reports of laboratory and clinical isolates have been published. This system has been increasingly...
متن کاملExpression of the MexXY-OprM efflux system in Pseudomonas aeruginosa with discordant cefepime/ceftazidime susceptibility profiles
While MIC distributions and percent susceptibility for cefepime and ceftazidime are generally similar among Pseudomonas aeruginosa, we noted an increasing discordance in susceptibility favoring ceftazidime at our hospital. Quantitative reverse transcriptase-polymerase chain reaction was utilized to explore overexpression of the MexXY-OprM efflux as the mechanism for this phenotype profile. Thir...
متن کامل[Antibiotic susceptibility of Pseudomonas aeruginosa].
The susceptibility of 128 clinical isolates of Pseudomonas aeruginosa against amikacin, kanamycin, gentamycin, minocycline, colistin, chloramphenicol, claforan , piperacillin and carbenicillin were tested. Piperacillin, carbenicillin, amikacin and claforan are effective against at least 54% of strains tested. The susceptibilities of microorganisms to antibiotics were evaluated in different poin...
متن کاملAntibiotic Susceptibility of Pseudomonas Aeruginosa Isolated from Cystic Fibrosis Patients
Abstract Background and Objective: Cystic fibrosis (CF) is an autosomal recessive genetic disease and Pseudomonas aeruginosa is one of the most common bacteria colonized in CF patients. Growing resistance of this bacterium to antibiotics now a day is a challenge of controlling infection in CF patient. In this study colonization of CF patients with Pseudomonas aeruginosa and antibiotic suscep...
متن کاملConstruction of New Genetic Tools as Alternatives for Protein Overexpression in Escherichia coli and Pseudomonas aeruginosa
Background: Pseudomonas protein expression in E. coli is known to be a setback due to signifi cant genetic variation and absence of several genetic elements in E. coli for regulation and activation of Pseudomonas proteins. Modifi cations in promoter/repressor system and shuttle plasmid maintenance have made the expression of stable and active Pseudomonas protein possible in bot...
