Background & Aims: Acinetobacter spp. are non-fermenting gram-negative coccobacilli that have emerged in recent three decades as major causes of nosocomial infections. Acinetobacter baumannii is the most common pathogen causing a wide spectrum of infections. Acinetobacter infections are difficult to treat, due to both the intrinsic resistance of the pathogen and its ability to readily acquire n...

background acinetobacter has become an important cause of different infections such as wound infection, due to its great ability to survive and spread in hospital settings and to develop resistance against many antibiotics. objectives the aim of this study was to investigate the antibiotic resistance among isolates of acinetobacter from wound infections during a 7-year period, from 2005 to 2011...

conclusions it seems that besides the variety and prevalence of blatem and blactx, enormous mechanisms such as porin and leaking systems (efflux pumps) are responsible for the information of the a. baumannii resistance to disinfectants. the study on an accurate consideration of the resistance in strains and other microorganisms is advised. results in the current study, 131 a. baumannii isolates...

Enterococcus is the second cause of urinary tract infections in hospitals and the third most common cause of nosocomial bacteremia. Overuse of antibiotics for the treatment of nosocomial infections, causes antibiotic resistance in enterococci resistant to antibiotics through their ability to acquire resistance to antibiotics through mutation or acquisition of genetic material carrying a resista...

The present study was done to evaluate the presence of antibiotic resistance genes in Lactococcus garvieae isolated from cultured rainbow trout, West Iran.The isolates were examined for antimicrobial resistance using disc diffusion method. Of the 24 strains tested, 21 were resistant to ampicillin (87.5%), 9 to erythromycin (37.5%) and 19 to tetracycline (79.1%). Fourteen strains were resistant ...

Introduction: Acinetobacter baumannii is a major cause of nosocomial infections which affect mainly disabled patients in intensive care units. The bacteria may acquire resistance to antibiotics and hence can seriously endanger antibiotic therapy. The most important problem facing treatment of A. baumannii is increasing reports of resistance to a wide range of antibiotics, including carbapenems,...

Objective(s):Helicobacter pylori (H. pylori) is a pathogenic bacterium that colonizes the stomachs of approximately 50% of the world’s population. Resistance of H. pylori to antibiotics is considered as the main reason for the failure to eradicate this bacterium. The aim of this study was to determine the rate of resistant H. pylori strains to various antimicrobial agents in different areas of ...

Staphylococcus aureus is colonized in the human nasal cavity and would contaminate hospital and therapeutic environments. This bacterium has a genetic diversity in terms of resistance to antimicrobial agents. Therefore, the purpose of this study was identificatied of Methicillin and Vancomycin resistant genes in Staphylococcus aureus strains which has been isolated from the nasal cavity. 189 pa...
