Introduction & Objective: One of the mechanisms of antibiotic resistance in gram negative bac-teria, particularly Klebsiella pneumonia strains, is the production of Extended-Spectrum β lactamase enzymes (ESBLs). Encoding genes of ESBLs are usually located on the plasmid and they are able to transfer to other gram-negative bacteria. Thus, due to the importance of resistance pattern recogniti...
resistance of streptococcus pneumoniae against penicillin is considered to be of great importance. while low-resistant strains could be treated by penicillin, treatment of highly resistant strains is very difficult and needs broad-spectrum antibiotics. this study was performed in imam khomeini medical center, tehran, iran, from 1999 to 2001 to evaluate pneumococcal resistance against penicillin...
prevalence of metalo- β-lactamase-producing (mbl) acinetobacter species in a tertiary care hospital.
background and objectives: acinetobacter causes a wide variety of illness in debilitated and hospitalized patients. carbapenem resistance in acinetobacter is an emerging problem and is a cause of concern as many nosocomial infections with acinetobacter are resistant to most other antibiotics. the present study was aimed to study metallo-β-lactamase (mbl) production in acinetobacter species. mat...
objective(s):helicobacter pylori (h. pylori) is a pathogenic bacterium that colonizes the stomachs of approximately 50% of the world’s population. resistance of h. pylori to antibiotics is considered as the main reason for the failure to eradicate this bacterium. the aim of this study was to determine the rate of resistant h. pylori strains to various antimicrobial agents in different areas of ...
a major concern in the last few years has been the fact that the cultural centers are keeping distance with what they have been established for and instead of reproducing the hegemony, they have turned into a place for resistance and reproduction of resistance against hegemony. because the cultural centers, as urban public spaces in the last two decades, have been the subject of ideological dis...
