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 ...
متن کاملPLASMID MEDIATED METAL AND ANTIBIOTIC RESISTANCE IN PSEUDOMONAS AERUGINOSA STRAINS ISOLATED FROM BURN PATIENTS
Pseudomonas aeruginosa is a leading cause of bum infections, and antibiotic- resistant strains of this bacterium are emerging due to extensive application of antibiotics in the bum unit of hospitals. In this study 50 strains of P. aeruginosa were isolated from bum patients infected with this micro-organism in the bum unit of a general hospital in Kerman, Iran over one year [May 1999-ApriI20...
متن کاملPlasmid-mediated quinolone resistance in pseudomonas putida isolates from imported shrimp.
Fourteen quinolone-resistant Pseudomonas putida isolates were recovered from imported frozen shrimp sold in the United States. Two isolates harbored plasmids with qnrA and qnrB genes. PCR and DNA sequencing of quinolone resistance-determining regions identified novel substitutions in GyrA (His139→Glu and Thr128→Ala) and GyrB (Thr442→Asn, Gly470→Ala, and Ile487→Pro) and previously reported subst...
متن کاملInvestigation of plasmid-mediated quinolone resistance among isolates obtained in a Turkish intensive care unit.
The aim of this study was to search for three plasmid-encoded, quinolone-resistant determinants: qnrA, qnrB, and qnrS. Thus, 460 Gram-negative strains belonging to 11 different genera (clinical, 347; non-clinical, i.e., from a rectal swab, 113), of which 40% were ciprofloxacin-resistant, were recovered from patients in an intensive care unit at the Istanbul Medical Faculty, Turkey, in the years...
متن کاملPlasmid-mediated Quinolone Resistance among Non-TyphiSalmonella enterica Isolates, USA
We determined the prevalence of plasmid-mediated quinolone resistance mechanisms among non-Typhi Salmonella spp. isolated from humans, food animals, and retail meat in the United States in 2007. Six isolates collected from humans harbored aac(6')Ib-cr or a qnr gene. Most prevalent was qnrS1. No animal or retail meat isolates harbored a plasmid-mediated mechanism.
