Background: Treatment of chronic sinusitis is complicated due to increase of antibiotic-resistant bacteria. The aim of this study was to determine the multidrug resistance (MDR) pattern of the bacteria causing chronic sinusitis in north of Iran. Methods: This cross-sectional study was carried out on patients with chronic sinusitis. Bacterial susceptibility to antimicrobial agents was determi...
Background and Objectives: widely use of antibiotics as therapy and uncontrolled discharge of them to receiving waters increased the percentages of antibiotic resistant bacteria in various environments which may cause problems in therapy. The aim of this study was to investigate the antibiotic resistance of E. coli, K. pneumoniae and P. aeruginosa bacteria isolated from urban and hospital waste...
antibiotic resistance is a phenomenon in which antibiotic used to treat bacteria becomes useless due to resistance mechanism. increased drug resistance and occurrence of multiple drug resistance in bacteria specificity nosocomial and urinary tract infection bacteria has reduced the possibilities of treating these infectious diseases. efflux pumps are one of the major mechanism of mdr in bacteri...

several heavy metal resistant bacterial strains were isolated from sediment and water samples collected from the persian gulf and enclosed industrial areas. all the isolated bacteria were identified by 16s rrna gene sequencing. isolated bacteria were tested for the presence of plasmids using the modified alkaline lysate method. the method was effective for identification and characterization of...
This study was conducted to evaluate the resistance to antibiotics in the western white shrimp propagation centers on pathogens of Vibrio bacteria. In Iran, the most important bacteria in the shrimp are the vibrio species. In Bushehr Province, due to the high efficacy of erythromycin antibiotics, streptomycyne oxytracycline and tremitoprim in bacterial diseases, were selected as the species. Th...

Background and purpose: Descriptive knowledge of the epidemiology of bacteria causing urinary tract infection (UTI) and their antibiotic resistance patterns is of great importance in evidence-based decision-making of physicians and health planners in a region. This study investigated the prevalence and resistance pattern of bacteria isolated from urinary tract infections in Amol, north of Iran,...
background : pathogenic bacteria because of beta-lactam antibiotic resistance genes are dangerous to society. this resistance due to esbl genes, plasmids and transposons that by receiving or mutation occurs. the most important factor beta-lactam antibiotic resistance is beta lactamase enzymes. the purpose of this study was to evaluate the frequency of hospital opportunistic pathogenic bacteria...
Abstract Background: Acinetobacter baumannii is an emerging pathogen of growing significance that has been more frequently isolated in nosocomial specimens. These bacteria have ability of gene transfer between its types and other bacteria as caused for resistance against antibiotics and resistance scattering of bacteria. The aim of this research is determination of resistance for antibiotics an...
