Over the past two decades, an epidemiologic emergence of methicillin-resistant Staphylococcus aureus (MRSA) infections has occurred from that of primarily hospital-associated to community-associated. This emergence change has involved MRSA of different pulsed-field types (PFT), with different virulence genes and antimicrobial resistance patterns. In this study we, evaluate the changes in PFT an...

BACKGROUND In developing countries, hospitalized burn victims are at high risk of nosocomial infections caused by Staphylococcus aureus. Risk factors include poor infection control practices, prolonged hospitalisation and limited capacity for laboratory microbiological analyses. These problems are compounded by widespread use of antibiotics that drives the spread of multi-drug resistant bacteri...

OBJECTIVE In low- and middle-income countries, bloodstream infections are an important cause of mortality in patients with burns. Increasingly implicated in burn-associated infections are highly drug-resistant pathogens with limited treatment options. We describe the epidemiology of bloodstream infections in patients with burns in a humanitarian surgery project in Iraq. METHODS We performed a...

background: quaternary ammonium compounds (qac), which contain benzalkonium chloride as the most widely used agent, are employed as wound and skin antiseptics, as well as disinfectants in hospitals. the resistance mechanism to disinfectants is usually determine by genes which are related to resistance to quaternary ammonium compounds, namely, qace, qacδe1, qacδe1 that are found in gram-negative...

background : pseudomonas aeruginosa , as an etiological agent, has a prominent infection role in serious burned patients. burned patients usually treated with antiseptic ointments such as silver sulfadiazine (ssd). this study evaluated the effectiveness of 1% ssd and different concentrations of silver nitrate solution (sns) on resistant isolates of p. aeruginosa .   methods : three groups of p....

Background and Aims: Acinetobacter baumannii (A. baumannii) is an important multidrug-resistant opportunistic pathogen frequently causing various nosocomial infections and is a serious threat to burn patients. These infections are usually caused by the outbreak strains. The aim of this study was to show antibiotic resistance pattern and molecular typing of A. baumannii genes isolates collected ...

The emergence of fluoroquinolone resistance among A. baumannii isolates is now of particular concern. Phenotypic and genotypic characteristics of resistance to ciprofloxacin among 50 Acinetobacter baumannii isolated from burn wound infections of Tehran were evaluated by E-test and broth microdilution in presence and absence of efflux pump inhibitor phenylalanine- arginine β-naphthylamide (PAβN)...

background and objectives : pseudomonas aeruginosa is one of the most important gram negative opportunistic bacteria which causes infection among burn patients. resistance to the antibiotics in this group of bacteria is increased due to the activity of extended spectrum β-lactamase (esbls) genes. in the current study, we investigated the prevalence of two genes (blaper-1 & blaoxa10) related β-l...
