BACKGROUND Pseudomonas aeruginosa remains a leading cause of severe wound infection and mortality in burn patients. OBJECTIVES The current study aimed to determine the prevalence of Ambler class A and D β-lactamases among P. aeruginosa isolated from infected burn injuries in Tehran, Iran. PATIENTS AND METHODS Bacteriological samples were taken from burn patients with clinical symptoms of bu...
conclusions high-level antibiotic resistance can occur as a result of multidrug efflux pumps combined with other mechanisms of resistance. however, the association between over-expression of these genes and highly resistant clinical isolates cannot be ignored. results our results confirmed 203 and 60 p. aeruginosa isolates from burn and non-burn specimens, respectively. the most antibiotic resi...
conclusions the efflux pump may play a role in antibiotic resistance in a. baumannii isolates. the ability of a. baumannii isolates to acquire drug resistance by the efflux pump mechanism is a concern. thus, new strategies are required in order to eliminate the efflux transport activity from resistant a. baumannii isolates causing nosocomial infections. background acinetobacter baumannii has em...
background pseudomonas aeruginosais an opportunistic pathogen which causes severe, acute and chronic nosocomial infections. these infections are difficult to eradicate since the organisms are usually multidrug-resistant. carbapenems are considered as the most effective drugs against these isolates. however, recent emergence of carbapenem-resistant p. aeruginosa has become a major healthcare pro...
background and objectives: pseudomonas aeruginosa is responsible for devastating nosocomial infections among severely burn patients. class c of cephalosporinase (ampc-β-lactamases) is important cause of multiple β-lactam resistance in p. aeruginosa . the aim of this study was to detect the ampc-β-lactamases producing isolates among carbapenem resistant p. aeruginosa isolated from burn patie...
conclusions the high rate of mdrpa and its ability to produce biofilm is an alarm for public health. the statistical analysis showed that biofilm production in the mdrpa isolates was significantly higher than that in the non–mdrpa isolates (p < 0.001). background pseudomonas aeruginosa possesses a variety of virulence factors and infections caused by multidrug-resistant p. aeruginosa (mdrpa) in...
BACKGROUND Pseudomonas aeruginosa possesses a variety of virulence factors and infections caused by multidrug-resistant P. aeruginosa (MDRPA) in burn patients are a public health problem. OBJECTIVES The aim of this study was to determine the antibiotic resistance pattern, the biofilm formation, the prevalence of MDRPA and two virulence genes (nan1 and exoA) among P. aeruginosa isolated from b...
BACKGROUND Acinetobacter baumannii has emerged as a highly troublesome pathogen and a leading cause of mortality and morbidity among hospitalized burn patients. OBJECTIVES The aims of this study were to determine the frequency of the AdeABC genes and the role of the efflux pump (s) in the imipenem resistance of A. baumannii strains isolated from burn patients. MATERIALS AND METHODS This stu...
antibiotic resistance of pseudomonas aeruginosa remains a major problem in burn patients. the main objective of this study was to determine the antibiotic resistance pattern and frequency of class 1 integrons among p. aeruginosa strains isolated from patients with burn wound infections in a new burn centre in guilan, iran.the bacterial isolates were collected from 182 patients with burn wound i...
conclusions our findings showed a high occurrence of metallo-β-lactamase production among p. aeruginosa isolates in burn patient infections in our region. also, there are p. aeruginosa isolates carrying the bla-vim-1 and bla-vim-2 genes in isfahan province. background metallo-β-lactamase-production among gram-negative bacteria, including pseudomonas aeruginosa, has become a challenge for treatm...
