Staphylococcus aureus is an etiological factor of severe infections in both hospital and ambulatory environments. As methicillin resistant Staphylococcus aureus strains spread quickly across healthcare centers resulting in life-threatening infections with increased mortality, they are considered more virulent than MSSA strains. Protein A, encoded by the spa gene, is one of the virulence factors...

A total of 382 isolates of methicillin-resistant Staphylococcus aureus originating from three Austrian regions and one adjacent Italian region (Vienna, Lower Austria, North Tyrol, and South Tyrol) were typed by DNA sequence analysis of the variable repeat region of the protein A gene (spa typing). The strain collection consisted of arbitrarily chosen isolates originating from clinical specimens...

Spondyloarthropathies (SpA) are characterised by dysregulation of the inflammatory processes and bone metabolism which may be clarified by gene expression profiles. Sharma and colleagues showed associations of axial SpA with the innate immune system, inflammation markers and markers of bone remodeling. Drawbacks of this study are the patient selection based on uveitis, which limits the extrapol...

The protein A encoding gene spa of four Staphylococcus aureus strains isolated from bovine clinical mastitis was amplified by PCR and sequenced. The four strains were selected after an initial screening of spa gene of 41 strains isolated from mastitic cows and were subjected to detailed investigations. According to the sequencing results the spa gene of three strains (M1, M2, M3) appeared with ...

Due to the importance of nanoparticles stability in industrial applications, in this research, stability of laponite nanoparticles dispersions containing different concentrations of sodium sulfonated polyacrylamide (SPA) was investigated in electrolyte media for oil reservoirs applications. In this regard, effect of parameters such as polymer concentration, temperature, and ionic strength were ...

Staphylococcus aureus is responsible for numerous mild to severe diseases in humans both hospital and community settings. This problem getting even worse multi-drug resistant S. aureus. Healthcare workers (HCWs) are a threat of MRSA carriage can serve as reservoirs. Therefore, this lead subsequent infection cause nosocomial outbreak MRSA. cross-sectional study involved 85 healthcare from surger...

Plants sense vegetative shade as a reduction in the ratio of red light to far-red light (R:FR). Arabidopsis (Arabidopsis thaliana) responds to a reduced R:FR with increased elongation of the hypocotyl and the leaf petioles as well as with an acceleration of flowering time. The repressor of light signaling, CONSTITUTIVELY PHOTOMORPHOGENIC1 (COP1), has been shown previously to be essential for th...

The paper examines face-to-face interaction in a simple two-person bargaining game with incomplete information about the division of a fixed sum of money in which each bargainer can either have costs to be subtracted from her bargaining agreement payoff or not. The bargaining events are observed by onlookers who make guesses of the cost situations of the participants. The work of Gauthier (1978...

Sheep pulmonary adenomatosis ([SPA] ovine pulmonary carcinoma) is a transmissible lung cancer of sheep that has been associated etiologically with a type D- and B-related retrovirus (jaagsiekte retrovirus (JSRV]). To date it has been impossible to cultivate JSRV in vitro and therefore to demonstrate the etiology of SPA by a classical approach. In addition, the presence of 15 to 20 copies of end...
