The 16S-23S intergenic spacer region in 218 strains of Salmonella isolated from four Italian hospitals during the period from 1977 to 1994 was analyzed by PCR ribotyping. This molecular typing technique allowed for the identification of seven different and specific electrophoretic profiles for the seven serovars S: enteritidis, S. london, S. anatum, S.(More)
In this paper a new algorithm for solving special Vandermonde systems is presented, useful when then points defining the matrix are thek th roots ofm complex numbers (n=km); if they are real and positive andn=2m, the usual case of real points symmetrically ranged around zero is obtained. The algorithm is based on an inverse matrix formulation by means of(More)
BACKGROUND The aim of this study was to characterize the spread of carbapenemase-producing Klebsiella pneumoniae (CPKP) in a tertiary level hospital using ongoing active surveillance with rectal swab cultures. Furthermore, this study analyzed the presence of CPKP in the clinical samples (CS) of a single patient as well as the evolution of Colistin-sensitive(More)
BACKGROUND Outbreaks of vancomycin-resistant Enterococcus faecium (VRE) strains is an emerging problem worldwide. Even if still relatively uncommon in European hospitals, infections caused by VRE have also been increasing recently in this continent. METHODS In this study, we characterized 50 consecutive VRE and 23 vancomycin-sensitive E. faecium (VSE)(More)
Alpha 2 macroglobulin, haptoglobin and fibrinogen plasma levels were simultaneously determined, as well as E.S.R., to test if a significant difference could be found among cancer, inflammatory diseases and control subjects. Haptoglobin was higher in the cancer group and fibrinogen in inflammatory diseases, but these selective increases are not believed to(More)
