conclusions the presence of bft gene in b. fragilis isolates wouldnot certainly result in diarrheaamong patients. there is not enough accordance between ddm and swedish e tests for antimicrobial susceptibility of b. fragilis for some antibiotics, although in other cases a good agreement was observed. background enterotoxigenic bacteroides fragilis (etbf) are one of the most important anaerobic ...

background and objective: pseudomonas aeruginosa has become a frequent cause of nosocomial infections, particularly in intensive care units (icus). many reports have documented high rates of resistance in this species to commonly-used broad-spectrum antibiotics. the aim of this study was to assess the in vitro activity of some antibiotics against pseudomonas aeruginosa strains to determine the ...

some plant extracts have been reported to exhibit antimicrobial properties. plant based pesticides appear to be an alternative for the synthetic pesticides because of their less dangerous impacts. the objective of this study was to assess the inhibitory activity of brassica napus water extract on mycelial growth of six phytopathogenic fungi rhizoctonia solani, phythophtora drechseleri, pythium ...

to evaluate the enhancement effect of berberis vulgaris var. integerrima seeds on the antibacterial activity of cephalexin and ceftizoxime against staphylococcus aureus and escherichia coli ethanol extract of the seeds were prepared. disk diffusion and broth dilution methods were used to determine the antibacterial activity of two cephalosporins in the absence and presence of the extract and it...

Conventional wisdom holds that reducing disk latency leads to higher disk utilization, maximizing disk utilization leads to higher throughput, employing a faster disk leads to better performance. All of this is true when building a conventional le or database system. In this paper we show that these principles can be misleading when applied to a media server. We examine a number of techniques t...

Performance isolation has long been a challenging problem for disk resource allocation in virtualized environments. While there have been many researches working on I/O performance isolation and disk utilization, none of them addresses the I/O performance isolation and disk utilization as a whole. To this end, we investigate the impact of current disk I/O performance isolation schemes on disk I...

We investigate the dynamical interaction between a galactic disk and surrounding numerous dark subhalos as expected for a galaxy-sized halo in the cold dark matter (CDM) models. Our particular interest is to what extent accretion events of subhalos into a disk are allowed in light of the observed thinness of a disk. Several models of subhalos are considered in terms of their internal density di...
