Colistin Resistance of Pseudomonas aeruginosa Isolated from Snakes in Taiwan
This study included fifty-eight isolates of P. aeruginosa from the oral cavity of snakes that were recruited from clinical cases, captive and wild snakes. The minimum inhibitory concentrations (MICs) for the determination of susceptibility were identified by the broth microdilution method. Polymerase chain reaction (PCR) was employed to detect β-lactamases genes. With regard to antipseudomonal ...
متن کاملCarbapenem and Fluoroquinolone Resistance in Multidrug Resistant Pseudomonas aeruginosa Isolates from Al-Zahra Hospital, Isfahan, Iran
Introduction: The major resistance mechanisms of Pseudomonas aeruginosa to fluoroquinolones and carbapenems are associated with the mutations in the genes gyrA and oprD encoding type II topoisomerases (DNA gyrase) and OprD porin, respectively. Method: In this cross-sectional study, sixty five clinical samples were collected from patients hospitalized in Al-Zahra Hospital of Isfahan, Iran. Susce...
متن کاملGenomic variations between colistin-susceptible and -resistant Pseudomonas aeruginosa clinical isolates and their effects on colistin resistance.
OBJECTIVES The emergence of colistin-resistant Pseudomonas aeruginosa is becoming a serious concern worldwide. We investigated genetic variations involved in the acquisition and loss of colistin resistance in three clinical isogenic P. aeruginosa isolates (GKK-1, GKK-2 and GKK-3) recovered from a single patient and assessed their impacts on colistin resistance. METHODS We applied whole genome...
متن کاملAntibiotic 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...
متن کاملAssociation Between Metallo-β-lactamases and Integrons with Multi-Drug Resistance in Pseudomonas aeruginosa Isolates
Pseudomonas aeruginosa is among the most important pathogens in the nosocomial infections. A genetic mobile element, the integron, is one of the major agents involved in dissemination of multi-drug resistance among gram negative bacteria. During a descriptive study from October 2009 to August 2010, some 130 P. aeruginosa clinical isolates were collected from different wards of three hospitals...
