Meropenem susceptibility breakpoint for Pseudomonas aeruginosa strains hyperproducing mexB mRNA

Encapsulated Pseudomonas Aeruginosa (pseudomonas Aeruginosa Mucosus) Strains.

Protein-to-mRNA Ratios Are Conserved between Pseudomonas aeruginosa Strains

Recent studies have shown that the concentrations of proteins expressed from orthologous genes are often conserved across organisms and to a greater extent than the abundances of the corresponding mRNAs. However, such studies have not distinguished between evolutionary (e.g., sequence divergence) and environmental (e.g., growth condition) effects on the regulation of steady-state protein and mR...

siRNA-mediated gene silencing of MexB from the MexA-MexB-OprM efflux pump in Pseudomonas aeruginosa

To gain insights into the effect of MexB gene under the short interfering RNA (siRNA), we synthesized 21 bp siRNA duplexes against the MexB gene. RT-PCR was performed to determine whether the siRNA inhibited the expression of MexB mRNA. Changes in antibiotic susceptibility in response to siRNA were measured by the E-test method. The efficacy of siRNAs was determined in a murine model of chronic...

Antimicrobial Resistance Profile of Pseudomonas Aeruginosa Strains

Abstract Background and Objectives: Pseudomonas aeruginosa is the most common organism, which is separated from the burn infections.  Due to increased antibiotic resistance, there are many problems to deal with the infections caused by Pseudomonas aeruginosa. This study aimed to determine the resistance to antibiotics against clinical isolates of Pseudomonas using phenotype me...

C-terminal region of Pseudomonas aeruginosa outer membrane porin OprD modulates susceptibility to meropenem.

We investigated the unusual susceptibility to meropenem observed for seven imipenem-resistant clinical isolates of Pseudomonas aeruginosa. These strains were genetically closely related, expressed OprD, as determined by Western blot analyses, and were resistant to imipenem (>5 microg/ml) but susceptible to meropenem (<1 microg/ml). The oprD genes from two isolates were entirely sequenced, and t...
