To develop a single multiplex real-time PCR assay to detect six different genetic types of carbapenemases already identified in Enterobacteriaceae (KPC, GES, NDM, IMP, VIM and OXA-48). A total 58 bacterial isolates were tested. Thirty previously characterized as resistant carbapenems documented by sequencing analysis carry the following genes: blaKPC type, blaGES blaIMP blaVIM blaOXA-48 blaNDM-1. These positive strains included 21 Enterobacteriaceae, 1 Acinetobacter baumannii 8 Pseudomonas...

ABSTRACT Metallo-β-lactamase enzymes (MβL) are encoded by transferable genes, which appear to spread rapidly among gram-negative bacteria. The objective of this study was develop a multiplex real-time PCR assay followed melt curve step for rapid detection and identification genes encoding MβL-type based on the amplicon melting peak. reference sequences all IMP VIM types, SPM-1, GIM-1, SIM-1 were downloaded from GenBank, primers designed obtain amplicons showing different sizes peak...

Inappropriate antibiotic use in normally self-limiting acute respiratory tract infections (RTIs), such as sore throat and the common cold, is a global problem an important factor for increasing levels of resistance. A new group international experts—the Global Respiratory Infection Partnership (GRIP)—is committed to addressing this issue, with interface between primary care practitioners their patients core focus. To combat overuse antibiotics community, facilitate change from prescribing...

We report the antimicrobial susceptibility patterns of most frequently isolated Gram-positive bacteria in Brazilian hospitals participating SENTRY Antimicrobial Surveillance Program. The strains were consecutively collected (one per patient) between January 2005 and September 2008 tested by reference broth microdilution methods at JMI Laboratories (North Liberty, Iowa, USA). A total 3,907 cocci analyzed. organisms from bloodstream infections Staphylococcus aureus (2,218 strains; 20.2%...

Emerging resistance phenotypes and antimicrobial rates among pathogens recovered from community-acquired urinary tract infections (CA-UTI) is an increasing problem in specific regions, limiting therapeutic options. As part of the SENTRY Antimicrobial Surveillance Program, a total 611 isolates were collected 2003 patients with CA-UTI presenting at Latin American medical centers. Each strain was tested central laboratory using Clinical Laboratory Standard Institute (CLSI) broth microdilution...

Abstract Background The incidence of bloodstream infection ( BSI ) varies according to the transplanted organ. Mortality can be as high 24%, with a significant impact on graft survival. Transplantation is risk factor for multidrug‐resistant MDR organisms, but comparison non‐transplanted population in single large cohort has not been described.
