Background and Objective: Efflux pumps are regarded as one of the most important mechanisms of antibiotic resistance in this era. Staphylococcus aureus is one of the bacterial groups with efflux pumps. The pumps’ activity is coded by specific genes. The aim of this study was to determine the phenotypic and molecular pattern of efflux pumps in the clinical isolates of methicillin-resistant...
conclusions metronidazole and vancomycin still seem to be most effective drugs for treatment cdi. objectives the aim of this study was to investigate the antimicrobial susceptibility patterns of c. difficile clinical isolates against antibiotics commonly used for treatment cdi in hospitalized patients. material and methods during a 12 month study, 75 c. difficile isolates were collected from 39...
بررسی شیوع اینتگرون در اشرشیا کلی و کلبسیلا در کودکان مبتلا به عفونت دستگاه ادراری مقاوم به چند دارو
Abstract Background: The aim of this study was to identify multidrug resistant isolates of Escherichia coli and K. pneumoniae causing urinary tract infections (UTI) in children and the occurrence of class 1, 2 and 3 integrons in the antibiotic resistant isolates.. Methods: A total of 200 urine samples were processed. Urine culture was done using conventional microbiological techniques. Bioc...
conclusion prevalence of p. aeruginosa producing esbl and mdr strains from our clinical samples and environment is still low. results the highest resistance rates from the isolated p. aeruginosa were shown against piperacillin, imipenem, cefotaxime, ceftriaxone, gentamicin, ceftazidime, aztreonam, and ciprofloxacin, respectively. seven isolates (9.2%) were esbl producers. more than 30% of the i...
Background & Aims of the Study: Methicillin-resistant staphylococcus aureus (MRSA) is considered as a major pathogen in public health concern. The objectives of this study were to firstly determine antibiotic sensitivity among Staphylococcus aureus isolated from traditional Iranian white cheese during 2015 from Hamedan province of Iran; and secondly to estimate the presence of ...
results fifty-three (53%) isolates were simultaneously resistant to erythromycin, azithromycin and clarithromycin (cross-resistance); while 8 (8%) isolates had variable macrolide susceptibility pattern. among the s. aureus isolates, the difference in prevalence of resistance to erythromycin between males and females was significant (p = 0.011). the frequency of erma, ermb, ermc, and msra genes ...
Background and purpose: The aminoglycoside modifying enzymes (AMEs) and class 1 integrons in clinical isolates of pseudomonas aeruginosa are the major factors leading to rapid spread of antibiotic resistance. The aim of the present study was to investigate the frequency of aac(6)-IIa, ant(2'')-Ia, and class 1 integrons in clinical isolates of pseudomonas aeruginosa. Materials and methods: For ...
Background and Aim: As one of the major causes of hospital and community acquired infections, Methicillin-resistant Staphylococcus aureus (MRSA) requires accurate and timely diagnosis. This study aimed to investigate the prevalence and antibiotic resistance patterns of MRSA in patients hospitalized in the Birjand-based Imam Reza hospital. Materials and Methods: In this cross-sectional study, a...
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 ...
Objective: In view of the national key project for infectious diseases “ the retreatment research of tuberculosis”, we determined the in vitro anti-mycobacterial activity of four drugs in the treatment, pasiniazid (Pa), moxifloxacin (Mfx), Rifabutin (Rfb) and rifapentini (Rft) in combination to multidrug-resistant and extensively drug-resistant mycobacterium tuberculosis. Method: Three-dimensio...
