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...

Two methicillin- and vancomycin-resistant Staphylococcus aureus strains, MI-VRSA and PA-VRSA, and Enterococcus faecalis DMC83006B, considered to be the potential donor of glycopeptide resistance to MI-VRSA, were studied. MI-VRSA is highly resistant to both glycopeptides, whereas PA-VRSA displays low-level resistance to vancomycin and reduced susceptibility to teicoplanin. We have analyzed the e...

In order to avoid microstructure degradation caused by low frequency induction heat in laser-induction hybrid deposition, this paper proposes a laser/ultra-high (UHF) deposition method. Microstructure observation is carried out reveal the effect of UHF on deposited layer. Results indicate that laser-UHF layer, under current density 1.14 × 108 A/m2, exhibits finer and fewer Laves phases than las...
