background and objectives: klebsiella species are of the most common bacteria involved in nosocomial and urinary tract infections. genetic elements such as class 1 integrons have an important role in the resistance development. in this study, the share of class 1 integrons, the genetic characterization of the integron cassettes and pfge profiles of the clinical klebsiella isolates are evaluated...
salmonella enterica serotypes are one of the most important food borne pathogens and significant public health concerns around the world in humans and other animal species. a total of eighty three epidemiologically unrelated clinical isolates of salmonella enterica serovars were subjected to antimicrobial susceptibility testing. eleven isolates (13.1%) which were resistant to at least 4 groups ...
The quantity of seafood imported and produced by domestic aquaculture farming has increased. Recently, it been reported that multidrug-resistant (MDR) Salmonella Typhimurium may be associated with seafood. However, information is limited to the antimicrobial resistance, virulence properties, genetic diversity S. recovered from This study investigated isolated catfish, shrimp, tilapia. A total 1...
BACKGROUND/AIM Altered redox status has been reported to play a significant role in the development of multidrug resistance (MDR) in leukemia cells. Human biliverdin reductase (hBVR) has been recently identified as a major cytoprotectant; however, its role in MDR has not been yet investigated. In the present study we evaluated the possible role of hBVR in MDR development in the human HL60 leuke...
Multidrug resistance can result from several factors and processes. Some types of multidrug resistance (MDR) were recognized whose patterns differ from pattern of P-glycoprotein (Pgp) associated MDR in several important ways. Although, there is limited evidence for effect of DHP on atypical MDR; based on some observations like noncompetitive inhibition of topoisomerase I by a DHP derivative (De...
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...
Multidrug resistance (mdr) can be defined broadly as the ability of a cell to survive ordinarily lethal doses of more than one drug. Clearly, such resistance is a critical problem in the treatment of fungal and bacterial infections and cancer. Four general, but nonexclusive, mechanisms give rise to multidrug resistance: 1) detoxification by enzymatic modification or cleavage of drug; 2) genetic...
Clinical strains of Stenotrophomonas maltophilia are often highly resistant to multiple antibiotics, although the mechanisms of resistance are generally poorly understood. Multidrug resistant (MDR) strains were readily selected by plating a sensitive reference strain of the organism individually onto a variety of antibiotics, including tetracycline, chloramphenicol, ciprofloxacin, and norfloxac...
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...
