the plant kingdom constitutes a source of new chemical compounds, which may be important due to their potential uses in medicine, or their other biological properties. in this study, the effects of galbanic acid (ga), a sesquiterpene coumarin from roots of ferula szowitsiana, were investigated as a modulator of antibiotic resistance in clinical isolates of staphylococcus aureus. isolates of s. ...
Background and Objective: One of the mechanisms involved in the resistance of Klebsiella pneumoniae to fluoroquinolones is AcrAB leakage pumps. In this study, the prevalence of Klebsiella pneumoniae isolates with AcrAB encoding genes and the role of permeation pumps in fluoroquinolone resistance were investigated. Materials and Methods: 165 samples from patients of Kermanshah Medical Centers ...
Ornithobacterium rhinotracheale (ORT) is a respiratory pathogen which has been isolated throughout the world from numerous bird species. The present study was designed to isolate and characterize the ORT from domestic turkeys, quails and pigeons. For this purpose, 250 samples from each bird species (turkey, quail and pigeon) with or without respiratory signs were tested by taking of tracheal...
Background & Aims: The antimicrobial effects of nickel nanoparticles on some bacterial strains such as S. aureus and E.coli have been shown in limited studies. The aim of this study was to investigate the inhibitory effects of nickel nanoparticles on biofilm formation by mupirocin resistant S. aureus isolates. Materials & Methods: In this study, 150 S. aureus isolates were collected fro...
background assessment of resistance genes is imperative, as they become disseminated to bacterial flora in plants and to the indigenous bacterial community, and thus ultimately contributes to the clinical problems of antibiotic resistant pathogens. objectives the research was to assess the antibiotic characteristics and incidence of sul3 genes of stenotrophomonas maltophilia isolates recovered ...
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: Bloodstream infections are the most important causes of morbidity and mortality in hospitalized patients. Blood culture plays an important role in identifying most of bacterial agents of bloodstream infections. Knowledge about bacterial agents of bloodstream infections and also antibiotic resistance of these bacteria are important. Antibiotic resistance among bacterial agents of blo...
Received: 6 Jul, 2015 Accepted: 16 Sep, 2015 Abstract Background & Aims: In recent years, the emergence of multi drug resistant Klebsiella pneumonia is responsible for many therapeutic problems all over the world. Nowadays carbapenems are often considered as the final options for antibiotic treatment of infections caused by most Gram-negative bacilli. The aim of this study was to dete...
bacterial resistance to antibiotics is a serious problem and is increasing in prevalence world-wide at an alarming rate. the antimicrobial susceptibility patterns of 1897 gram-positive bacterial isolates were evaluated. the minimum inhibitory concentration (mic) of isolates which comprised staphylococcus aureus (927 isolates), coagulase-negative staphylococci (cns; 425 isolates), enterococcus f...
conclusions all the bacterial isolates were associated with a high resistance to various antibiotics and this resistant pattern could be confirmed by detection of a particular gene for each bacterium. objectives this study examined bacteremia in cancer patients from two medical centers regarding isolates and spectrum of antibiotic resistance pattern. patients and methods this was a prospective ...
