This laboratory study simultaneously was conducted to evaluate the resistance to heavy metals, silver, cadmium and a number of commonly used antibiotics. Sampling was done in 2014 of the two silver workshops in Isfahan, and the inlet of phase 2 of Shahin Shahr wastewater treatment plant, Isfahan. To isolate resistant bacteria to metal silver and cadmium and review multiple resistance to other m...

background: reduced susceptibility of clostridium difficile to antibiotics is problematic in clinical settings. there is new evidence indicating the cotransfer of toxin-encoding genes and conjugative transposons encoding resistance to antibiotics among different c. difficile strains. to analyze this association, in the current study, we evaluated the frequency of toxigenic c. difficile among th...

 The present study was aimed to evaluate the antimicrobial resistance and the presence of antibiotic resistance genes in Vibrios spp. isolated from seafood. A total of 72 isolates of Vibrio in 6 species including V. parahaemolyticus, V. vulnificus, V. alginolyticus, V. harveyi, V. mimicus and V. cholerae were examined. The results revealed that all isolates were expressing multiple antibiotic r...

The discovery of gramicidin, penicillin, streptomycin, and the numerous other antibiotics known today has contributed materially to the list of therapeutic agents available against micro-organisms. However, the immediate enthusiasm which greeted their introduction has had to be checked by the realization that many of the important organisms affected readily develop resistance to the antibiotic ...

conclusions: in the present study, we have figured out that a number of the important anaerobic infections treatment antibiotics have lost partly or totally their effectiveness on b. fragilis. background: bacteroides fragilis are among the most important anaerobic bacteria behind most of the anaerobic infections. they have acquired resistance to essential treatment antibiotics of anaerobic infe...
