The aim of the study was the assessment of the usefulness of commercially available systems for rapid identification of staphylococci. API STAPH (bioMerieux, France), ID 32 STAPH (bioMerieux, France), GPL (HTL, Poland) and Staph-Zym (Rosco, Denmark). The identifications were carried out according to producer's instruction. The material for the study comprised 76 staphylococcal strains, coagulase-positive and coagulase-negative. The strains were isolated from throat, nasal, wound, bone slivers, pus and blood of inpatients and from throat and nasal swabs of outpatients. Besides that, for the study staphylococcal strains were obtained from the American Collection of Typical Cultures (ATCC) and from the Polish Collection of Microorganisms (PCM). All tested strains were identified on the basis of classic biochemical tests. In the light of obtained results it is concluded that the commercial system most suitable for identification of staphylococci was ID 32 STAPH (bioMerieux), which has a wide spectrum of species identifiable with it and the highest percent (95%) of correctly identified species. The least suitable system was the GPL 15 (HTL, Poland).

Staphylococcus aureus can use an alternative pathway to be internalized by osteoblasts in absence of β1 integrins.

Staphylococcus aureus main internalization mechanism in osteoblasts relies on a tripartite interaction between bacterial fibronectin-binding proteins, extracellular matrix soluble fibronectin, and osteoblasts' β1 integrins. Caveolins, and particularly caveolin-1, have been shown to limit the plasma membrane microdomain mobility, and consequently reduce the uptake of S. aureus in keratinocytes.

Background And Objective: Dalbavancin is increasingly used for the long-term treatment of chronic osteoarticular infections. A population pharmacokinetic/pharmacodynamic (PK/PD) analysis for assessing the relationship between dalbavancin exposure and C-reactive protein (C-RP) over time was conducted.
Methods: Non-linear mixed-effect modeling was fitted to dalbavancin and C-RP concentrations.

Background: Alcoholism associates with increased Staphylococcus aureus bacteremia incidence and mortality. The objective was to compare disease progression, treatment and prognosis of Staphylococcus aureus bacteremia in alcoholics versus non-alcoholics.
Methods: The study design was a multicenter retrospective analysis of methicillin-sensitive Staphylococcus aureus bacteremia with 90-day follow-up.
