Background: Staphylococci are recognized worldwide as one of the most important etiological agents of bovine mastitis due to their virulence factors such as their ability to penetrate inside mammary epithelial cells and their ability to form biofilm. Aims: The objectives of this study were to establish a model of primary mammary epithelial cells origin...
Introduction: A large number of infectious processes are associated with opportunistic microorganisms. The phenotype antibiotic resistance such pathogens is multidrug-resistant strains the presence various β-lactamases. Our objective was to determine phenotypic and genotypic features staphylococci, enterobacteria, non-fermenting Gram-negative bacteria – cause diseases in patients health facilit...
background : reports on the association of nosocomial bacterial infections with indwelling medical devices such as intravenous catheters (ivc) has increased in recent years. the potential to form biofilm on these devices seems to be the main reason for establishment of such infections. the aim of this study was to measure the potential of biofilm formation by bacterial isolates from ivcs. metho...
Dalbavancin, tested against 146 staphylococci, was more potent than other drugs tested, with an MIC at which 50% of staphylococci were inhibited of 0.03 microg/ml and an MIC at which 90% of staphylococci were inhibited of 0.06 microg/ml by microdilution. For all strains, MICs of vancomycin, linezolid, ranbezolid, oritavancin, daptomycin, and quinupristin-dalfopristin were </=4.0 microg/ml. Dalb...
A significant percentage survival, representing a large number of viable cells, can occur in a Staphylococcus aureus population exposed to concentrations of mupirocin up to 1,000 times the minimum inhibitory concentration. An elevated ratio of minimum inhibitory to minimum bactericidal concentration of mupirocin with staphylococci was recorded. Staphylococci which survive exposure to mupirocin ...
A prospective study was conducted to determine the prevalence of aminoglycoside-resistant Staphylococcus aureus and coagulase-negative staphylococci before and after the introduction of amikacin as the sole aminoglycoside used in our burn unit, adult intensive care unit, and neonatal intensive care unit. Pharyngeal or endotracheal cultures, as well as superficial surveillance cultures, were col...
Objectives: Staphylococci were most prominent factors that responsible for skin, soft tissue and foreign body infections. Gaining resistance to methicillin and various antibiotics in these microorganisms over the years increased morbidity and mortality, especially in hospitalized patients. In such situations number of preferred antibiotics was limited. The aim of this study was to investigate i...
