Coagulase-negative staphylococci (CoNS) are the main cause of catheter-related infections, especially among immunosuppressed and neutropenic patients, as well as a source of bacterial contamination in blood cultures. Using biochemical identification and pulsed-field gel electrophoresis (PFGE), we sought to identify possible clonal isolates of bacteremia in patients with central lines in an onco...

The development of sensitive and non-invasive "liquid biopsies" presents new opportunities for longitudinal monitoring of tumor dissemination and clonal evolution. The number of circulating tumor cells (CTCs) is prognostic in multiple myeloma (MM), but there is little information on their genetic features. Here, we have analyzed the genomic landscape of CTCs from 29 MM patients, including eight...

Women with urinary tract infections (UTIs) in California, USA (1999-2001), were infected with closely related or indistinguishable strains of Escherichia coli (clonal groups), which suggests point source dissemination. We compared strains of UTI-causing E. coli in California with strains causing such infections in Montréal, Québec, Canada. Urine specimens from women with community-acquired UTIs...

background and objectives: the emergence of plasmid-mediated ampc (pampc) β-lactamases conferring resistance to third-generation cephalosporins has become a major clinical concern worldwide. the aims of this study were to determine the prevalence of pampc-producing e. cloacae isolates and typing of them in qazvin and tehran provinces, iran. materials and methods: a total of 120 cefoxitin non-su...

Spread of genetically diverse Staphylococcus aureus characterized with multi-antibiotic resistance and regulated by high level agr functionalities in several communities southwest Nigeria was investigated evaluated for infection control. pathotypes recovered from 256 cases including purulent pus skin infections, soft tissue aspirates, wounds, otorrhea, eye, throat endocervical infections were a...

Increasing anitmicrobial resistance among foodborne pathogens has prompted calls for the reduction of anitmicrobial use in livestock to prevent future emergence or resistance. In the case of Salmonella enterica, clonal dissemination may play a more critical role in regional changes in antimicrobial resistance in Salmonellae than antimicrobial selection pressure. Multi-resistant Salmonella Typhi...
