In a period of nine months, 225 strains of Gram-negative bacilli isolated from burns were identified by a variety of tests in two burn centers in Tehran. The most common species were Pseudomonas aeruginosa, Pseudomonas fluorescens, Escherichia coli, Enterobacter agglomerans, Enterobacter cloacae and Klebsiella pneumoniae. Many strains of acinetobacter spp, providencia spp, proteus spp, ser...

Fortimicin A, a pseudodisaccharide aminoglycoside, was found to have broad-spectrum activity against most clinically important aerobic and facultatively anaerobic bacteria, except Pseudomonas aeruginosa, some other Pseudomonas species, and streptococci. It was comparable to amikacin in its level of activity (minimum inhibitory concentrations) and spectrum of activity (except for the lack of act...

background and objectives: infection is the most common problem following burn injury. selection and dissemination of intrinsic and acquired resistance mechanisms increase the probability of burn wound colonization by resistant species including pseudomonas aeruginosa. multi-drug resistant pseudomonas aeruginosa has frequently been reported as the cause of nosocomial outbreaks of infection in b...

INTRODUCTION Pseudomonas aeruginosa isolates related to nosocomial infections are often resistant to multiple antibacterial agents. In this study, antimicrobial combinations were evaluated to detect in vitro synergy against clinical isolates of P. aeruginosa. METHODS Four clinical P. aeruginosa isolates were selected at random among other isolates from inpatients treated at the public Univers...

One hundred clinical isolates resistant to ceftazidime and/or cefotaxime were examined for susceptibility to cefepime. The most frequently encountered ceftazidime-cefotaxime-resistant strains belonged to the genera Enterobacter, Pseudomonas, and Citrobacter. Among these strains, 92% were resistant to cefoperazone, 91% were resistant to cefotaxime, 84% were resistant to ceftazidime, and 6% were ...

Figure 1. Antimicrobial-resistant pathogens causing nosocomial infections in intensive care units [1]. Left, Drugs and the organisms resistant to them. Shaded bars denote the percentage of resistant isolates ( SD) during 1998–2002. Bullet points denote the percentage of resistant isolates during 2003 only. Right, No. of resistant isolates during 2003 and increase in the percentage of resistant ...

In this study antimicrobial activity of ZnO nanoparticles and TiO2 nanoparticles on the most common pathogen bacterium Pseudomonas aeruginosa was evaluated. P. aeruginosa is one of the prevalent pathogen that caused nosocomial infection. It is generally multi-drug resistant. Pseudomonas aeruginosa (ATCC 27853) were cultured on nutrient agar medium (NA) for 24h at 37°C. TiO2 and ZnO nanoparticle...

Background and Aims: The indiscriminate use of antibiotics can lead to antibiotic resistance in the treatment of infections caused by bacteria such as Pseudomonas aeruginosa. The presence of integrons in Pseudomonas is clearly associated with multidrug resistances. Therefore, this study aimed at tracking class I, II and III integrons of antibiotic-resistant isolates of Pseudomonas aeruginosa th...
