AMINOGLYCOSIDE RESISTANCE GENES IN Pseudomonas aeruginosa ISOLATES FROM CUMANA, VENEZUELA

Antibiotic resistance profiles of Pseudomonas aeruginosa isolates containing virulence genes

Background: A most common opportunistic pathogen, Pseudomonas aeruginosa is present in both humans and animals and responsible for various nosocomial infections and healthcare settings related infections. Different virulence genes like; oprL (membrane lipoprotein L) and toxA (exotoxin A i.e. ETA) in P. aeruginosa, assist in its pathogenicity, toxicity and contribute to high antibiotic resistanc...

Aminoglycoside resistance in Pseudomonas aeruginosa.

Resistance due to aminoglycoside modifying enzymes in Pseudomonas aeruginosa isolates from burns patients.

BACKGROUND & OBJECTIVE Enzymatic modifications of aminoglycosides result in high-level resistance in numerous bacterial species. However, the data on this aspect are elementary in our country. The present study was therefore designed to determine resistance rates and patterns, and to find out the prevalent aminoglycoside modifying enzymes (AMEs) in clinical isolates of Pseudomonas aeruginosa fr...

Molecular Investigation of Outer Membrane Channel Genes Among Multidrug Resistance Clinical Pseudomonas Aeruginosa Isolates

Background: Multidrug resistance Pseudomonas aeruginosa (MDRPA) is most important issue in healthcare setting. It can secrete many virulence effector proteins via its secretion system type (T1SS-T6SS). They are using them as conductor for delivering the effector proteins outside to begins harmful effect on host cell increasing pathogenicity, competition against other microorganism and nutrient ...

Contribution of the MexXY multidrug transporter to aminoglycoside resistance in Pseudomonas aeruginosa clinical isolates.

MexXY is an aminoglycoside-inducible multidrug transporter shown to contribute to intrinsic and acquired aminoglycoside resistance in laboratory isolates of Pseudomonas aeruginosa. To assess its contribution to aminoglycoside resistance in 14 clinical isolates demonstrating a panaminoglycoside resistance phenotype unlikely to be explained solely by aminoglycoside modification, expression of mex...
