Pseudomonas aeruginosa is an opportunistic pathogen affecting immunocompromised patients. It is known as the leading cause of morbidity and mortality in cystic fibrosis (CF) patients and as one of the leading causes of nosocomial infections. Due to a range of mechanisms for adaptation, survival and resistance to multiple classes of antibiotics, infections by P. aeruginosa strains can be life-th...

in this study, among the 21 diesel-degrading bacteria that were isolated from an oil-polluted area in fars (iran), 6 bacterial strains were tested for their capability to metabolize and grow on diesel oil by degrading its hydrocarbons content. the biochemical characteristics and 16s rrna sequence analysis of diesel-degrading bacteria showed that these strains were related to the genus pseudomon...

The antibacterial activity and enzymatic inactivation of lividomycin, a new aminoglycosidic antibiotic, were studied with 13 strains of Pseudomonas aeruginosa. The minimal inhibitory concentration of lividomycin was 12.5 to 25 mug/ml, and three strains were resistant to high concentrations of lividomycin (more than 200 mug/ml). It was found that P. aeruginosa TI-13 and K-11, highly lividomycin-...

Pseudomonas aeruginosa is an opportunistic human pathogen and is the leading cause of nosocomial infections especially in immune compromised patients. In recent years, a considerable increase in the prevalence of multidrug resistance (MDR) P. aeruginosa has been noticed with high morbidity and mortality, hence requiring antibiotic susceptibility testing on a regular as well as a periodic basis....

The biodegradation of hexadecane by five biosurfactant-producing bacterial strains (Pseudomonas aeruginosa UG2, Acinetobacter calcoaceticus RAG1, Rhodococcus erythropolis DSM 43066, R. erythropolis ATCC 19558, and strain BCG112) was determined in the presence and absence of exogenously added biosurfactants. The degradation of hexadecane by P. aeruginosa was stimulated only by the rhamnolipid bi...

The effects of ceftizoxime and gentamicin alone and in combination were determined against 100 Pseudomonas aeruginosa strains. Concentrations of 32 micrograms of ceftizoxime and 8 micrograms of gentamicin per ml inhibited 22 and 43% of the strains, respectively. At concentrations of ceftizoxime and gentamicin that are readily achievable in serum, 15 strains were affected synergistically and 17 ...

UNLABELLED INTRODUCTION Species and resistance rate of current pathogens is important for determining the appropriate treatment. P. aeruginosa is an essential issue in the group of patients with ear problems. The number of infections and relapses caused by this pathogen has been increasing with high percentage of antibiotic resistant strains responsible for treatment failure. Aim. The purpose o...

BACKGROUND Metallo-beta-lactamase (MBL) producing Pseudomonas aeruginosa in the burn patients is a leading cause of morbidity and mortality and remains a serious health concern among the clinicians. OBJECTIVES The aim of this study was to detect MBL-producing P. aeruginosa in burn patients and determine multidrug-resistant (MDR) strains, and respective resistance patterns. PATIENTS AND METH...

Ocular bacterial keratitis, often associated with Pseudomonas aeruginosa bacterial infection, commonly occurs in contact lens wearers and may lead to vision impairment. In this study, we analyzed the contribution of neutrophil extracellular traps (NETs) to the mediation of protection during ocular keratitis. Both invasive and cytotoxic P. aeruginosa clinical isolates induced NET release by neut...
