introduction: multi-drug resistant (mdr) p. aeruginosa is constantly increasing and causing severe issues in combatting widely spread health problems. the aim of this study was to assess colistin susceptibility in mdr p. aeruginosa isolates obtained from different infection sites. methods: ninety clinical isolates of p. aeruginosa were collected from different hospitals of the tabriz university...

abstract       background and objective: probiotics are living microorganisms that have beneficial effects on the health of digestive system. the aim of this study was to evaluate the antimicrobial ability of acidic and neutral supernatants (culture supernatant) of lactic acid bacteria against common bacterial pathogens.        methods: four species of lactic acid bacteria (lactobacillus planta...

background: nowadays, nosocomial infection with multidrug-resistant acinetobacter is an important problem in the world, which is facing wide spectrum antibiotics and hence has become resistant. m aterials and methods: in this study, positive cultures of acinetobacter from one hundred clinical samples in seven hospitals from tehran during 2012-2013 were collected for checking antibiotic suscepti...

objectives: staphylococcus aureus is an important cause of serious infection in both hospital and the community. methicillin-resistant s. aureus (mrsa) is associated with high morbidity and mortality rates with rapid development of resistance. there is a need for early and reliable detection of mrsa infection to direct antibiotic therapy, and more effectively control cross-infection. in this st...

The Vitek GPS-TA card (Vitek Systems, Hazelwood, Mo.) was compared with single-concentration broth microdilution and disk diffusion methods using high-content disks for the detection of high-level resistance to gentamicin and streptomycin in 99 isolates of enterococci (81 Enterococcus faecalis isolates and 18 Enterococcus faecium isolates). The GPS-TA card accurately detected high-level resista...

introduction: many people are used medicinal plants due to natural, low risks and complications, and low costs as compared with the synthetic drugs. incidence of drug resistance against chemical antimicrobial drugs has led the use of medicinal plants for treatment of infections in recent years. the aim of this study was to examine possible antibacterial effects of four herbal plants in vitro.  ...

Pseudomonas aeruginosa is the most common pathogen infecting the lungs of patients with cystic fibrosis (CF). Improved antimicrobial chemotherapy has significantly increased the life expectancy of these patients. However, accurate susceptibility testing of P. aeruginosa isolates from CF sputum may be difficult because the organisms are often mucoid and slow growing. This study of 597 CF isolate...

Increasing antibiotic resistance in gram-negative bacteria has recently renewed interest in colistin as a therapeutic option. The increasing use of colistin necessitates the availability of rapid and reliable methods for colistin susceptibility testing. We compared seven methods of colistin susceptibility testing (disk diffusion, agar dilution on Mueller-Hinton [MH] and Isosensitest agar, Etest...

Ticarcillin and clavulanic acid in combination were tested against 40 Pseudomonas aeruginosa isolates resistant to ticarcillin by disk diffusion. A total of 21 isolates (53%) were susceptible to ticarcillin-clavulanate by disk diffusion, under currently recommended criteria for ticarcillin susceptibility. Macro-broth dilution tests (ticarcillin plus clavulanic acid, 2 micrograms/ml) confirmed s...
