Background & Aims : Cefepime is one of the fourth generations of cephalosporins known to be active against a wide range of bacteria. Cefepime is usually used for treatment of infections caused by multi-drug resistant bacteria. The aim of this study was the evaluation of the effect of this antibiotic on clinical E.coli isolates. Materials & Methods : A total of 100 isolates of E.coli were ...
Objective(s): Stenotrophomonas maltophilia has emerged as an important opportunistic nosocomial pathogen due to its intrinsic and acquired resistance to a wide range of antimicrobial agents. The present study aimed to investigate the occurrence of antibiotic resistance and resistance mechanisms among clinical isolates of S. maltophilia from Iranian patients.<...
Background and Aim: Rapid and precise typing of E.coli is a prerequisite for epidemiological surveillance and controlling of infection caused by this bacterium. The present study was conducted to determine the molecular diversity of E.coli strains isolated from human and swimming pools samples using Enterobacterial Repetitive Intergenic Consensus (ERIC) method. Materials and Methods: This was ...
Background: Avian pathogenic Escherichia coli (APEC), which is the causative agent of colibacillosis, harbors several putative virulence genes. An important trait of APEC for both poultry and public health is antibiotic resistance. Objectives: In the present study, some potential virulence genes of APECs isolated from Northeast of Iran and their resistance to the quinolones antibiotics were stu...
Abstract Background: Staphylococcus aureus is one of the most common infectious bacterial pathogens. TSST-1 and enterotoxins are the major virulence factors of this organism which are superantigens and cause the toxic shock syndrome. The toxin-encoding genes are located on pathogenicity islands with the ability to move to non-toxigenic strains. This study was done to determine the frequency of ...
Background :Nowadays beta lactamase-producing multiple-drug resistance Klebsiella pneumoniae is as an important factor in nosocomial infections which has produced therapeutic difficulties in worldwide. The purpose of this study was to identify KPC-producing K. pneumoniae (blakpc) in clinical samples in Iran. Materials and Methods: After identification of isolates in species level using cultura...
Introduction: The strains of Pseudomonas aeruginosa are known as an opportunistic pathogen that can cause infections in humans and animals. Metallo-β-lactamases (MBLs) are the most significant factors of resistance to carbapenem antibiotics in these bacteria. This study was designed to identify the MBLs producing P. aeruginosa isolates in three hospitals of Tehran, Iran. Methods: Tota...
Background: Carbapenemase genes have been spread among strains of Klebsiella pneumoniae that make them resistant to carbapenems. Hence, the present study aimed to study the prevalence of carbapenmase genes within K. pneumoniae isolates in Kermanshah medical centers. Methods: Sixty isolates of K. pneumoniae were collected and identified using API kit. Then, antibiotic susceptibility of isolat...
The increasing incidence of candidiasis and antifungal resistance as well as the introducing of new antifungal has recently encouraged performing of fungal susceptibility testing. The aim of this study was to evaluate the susceptibility profile of Candida species isolated from patients admitted to Yazd central laboratory to fluconazole. We used the broth microdilution method to evaluate the sus...
Background and Objectives: Enterococci as a part of the normal flora of human gastrointestinal tracts can cause infections in children and adults who have a weaker immune system. The aim of this study was to determine and compare vancomycin, gentamicin, erythromycin and tetracycline resistance in enterococci isolated from Tabriz Children’s Hospital. Materials and Methods: In this l...
