Antibacterial Effect of Matricaria chamomilla Alcoholic Extract against Drug-Resistant Isolates Staphylococcus aureus and Pseudomonas aeruginosa

Background and Objective: Efflux pump inhibitors (EPIs) can block efflux pumps and are helpful in potentiating the activity of aminoglycosides against Pseudomonas aeruginosa. The present study compared the effects of phenylalanine-arginine beta naphthylamide (PAβN) and curcumin on aminoglycoside minimum inhibitory concentration (MIC) on Pseudomonas aeruginosa clinical isolates. Materials and M...

We studied the prevalence of ceftazidime resistance in Pseudomonas aeruginosa and the rates of extended-spectrum β-lactamase (ESBL), AmpC β-lactamase (AmpC) and metallo-β-lactamase (MBL) production among the ceftazidime resistant Pseudomonas aeruginosa. A very high rate of MBL production was observed, which suggested it to be an important contributing factor for ceftazidime resistance among Pse...

Pseudomonas aeruginosa, an important opportunistic pathogen causing a wide range of acute and chronic infections.The present study was undertaken to detect the Metallo β lactamase in isolated of Pseudomonas aeruginosa which was isolated from wound infection and evaluated their susceptibility patterns.The presence of the MBL enzyme was detected by phenotypic confirmatiory tests are IMIPENEM-EDTA...

INTRODUCTION Imipenem-resistant Pseudomonas aeruginosa resulting from metallo-β-lactamases has been reported to be an important cause of nosocomial infection and is a critical therapeutic problem worldwide, especially in the case of bacteremia. OBJECTIVES To determine the frequency of metallo-β-lactamases among imipenem-resistant Pseudomonas aeruginosa isolates and to compare methods of pheno...

background : lactobacilli are the well known friendly bacteria for their probiotic activities against pathogens. the inhibitory activity of different strains of lactobacilli either obtained as commercial products or isolated from human feces was investigated against the clinical isolates of pseudomonas aeruginosa. the isolates were selected as the most resistant strains when challenged with ant...

background: failure in the treatment of burn patients infected with pseudomonas aeruginosa could happen as a result of the acquisition of antibiotic resistance, including carbapenems. objectives: the aim of the present study was to investigate the phenotypic and genotypic characteristics of the pseudomonas aeruginosa strains, isolated from burn patients. patients and methods: during a 12 month ...

Pseudomonas species are opportunistic pathogens with implications in a wide range of diseases including cystic fibrosis and sickle cell anaemia. Because of their status as multidrug resistant (MDR) and extremely drug resistant (XDR) bacteria Pseudomonas species represent a threat to public health. Prevalence, antibiogram and associated antibiotic resistant genes of Pseudomonas species isolated ...

BACKGROUND AND OBJECTIVES Carbapenem resistant Pseudomonas aeruginosa is a serious cause of nosocomial infections. The main purpose of the study is to determine the prevalence rate of imipenem resistant Pseudomonas aeruginosa carrying metallo-ß-lactamase (MBL) genes. MATERIAL AND METHODS 236 Pseudomonas aeruginosa isolates were collected from teaching hospitals of Ahvaz University of Medical ...
