An Internet-based Document Delivery Service (DDS) has been developed within the framework of the CNR (Italian National Research Council) Project BiblioMIME, in order to take advantage of new Internet technologies and promote co-operation among CNR and Italian university libraries. Adopting these technologies changes the traditional organisation of DDS and may drastically reduce costs and delive...

background. this study evaluated the antimicrobial activity of tetraacetylethylenediamine-sodium perborate (taed-sp) in comparison to 2.5% and 5% sodium hypochlorite (naocl) against enterococcus faecalis. methods. a standard suspension of e. faecalis was inoculated on 60 plates containing mueller-hinton agar culture medium. four sterile disks of beckman filtration paper were placed on each plat...

PURPOSE The present study was undertaken to detect metallo-beta-lactamase (MBL) in nosocomial isolates of Pseudomonas aeruginosa by four different phenotypic methods. METHODS Ninety-one consecutive P. aeruginosa isolates were subjected to susceptibility testing by disc-diffusion assay and Vitek 2. Imipenem resistance was determined by three different methods (disc-diffusion, Vitek 2 and E tes...

INTRODUCTION Resistance to antimicrobials has become a serious global health concern complicating treatment strategies and increasing health-care costs. The extended-spectrum beta-lactamase producing bacteria stand out as bacteria of great epidemic concern among Gram negative bacilli. Control and appropriate interventions for antimicrobial resistance depend on effective surveillance and knowled...

background aeromonas hydrophila cause one of the most important diseases in fishes and lead to economic losses, and may be contaminated human beings. objectives the current research aimed to investigate the anti-bacterial activity shown by the extracts prepared from different parts of olea europea, myrtus communis, thymus vulgaris, rosmarinuis officinalis, and achillea falcata that grow in syri...

Laboratory differentiation of erythromycin resistance phenotypes is poorly standardized for pneumococci. In this study, 85 clinical isolates of erythromycin-resistant (MIC > or = 1 microg/ml) Streptococcus pneumoniae were tested for the resistance phenotype by the erythromycin-clindamycin double-disk test (previously used to determine the macrolide resistance phenotype in Streptococcus pyogenes...

β-lactams are the most widely used group of antimicrobials. However, increasing resistance to these valuable drugs in uropathogens, mediated principally by β-lactamases, has become a major concern. The present study was undertaken to determine the prevalence of Extended Spectrum β-Lactamase (ESBL) producers in clinical isolates of urine specimens, collected from various healthcare centres acros...

BACKGROUND The resistance of aminoglycosides in strains that produce beta-lactamase can be developed through the multidrug resistant encoding genes carried by common plasmids. Recently, the association between 16S rRNA methyltransferase resistance and beta-lactamase enzymes carried by the same plasmids has drawn increased attention from researchers, particularly the association in aminoglycosid...
