Jun 1, 2019 · Abstract. Characteristics of Staphylococcus aureus infections include biofilm formation, leading to the spread of bacteria to the bloodstream causing sepsis and metastatic infections. In particular, in methicillin-resistant S. aureus (MRSA) infections, biofilm formation critically hampers treatment and causes poor prognosis.
Jul 16, 2021 · S. aureus forms a complex structure of extracellular polymeric biofilm that provides a fully secured and functional environment for the formation of microcolonies, their sustenance and recolonization of sessile cells after its dispersal.
Jul 17, 2023 · Staphylococcus aureus is Gram-positive bacteria (stain purple by Gram stain) that are cocci-shaped and tend to be arranged in clusters that are described as “grape-like.” On media, these organisms can grow in up to 10% salt, and colonies are often golden or yellow (aureus means golden or yellow).
Mar 8, 2017 · Staphylococcus aureus is an important human pathogen that causes wide range of infectious conditions both in nosocomial and community settings. The Gram-positive pathogen is armed with battery of virulence factors that facilitate to establish infections in the hosts.
Staphylococcus aureus is a gram-positive spherically shaped bacterium, a member of the Bacillota, and is a usual member of the microbiota of the body, frequently found in the upper respiratory tract and on the skin. It is often positive for catalase and nitrate reduction and is a facultative anaerobe that can grow without the need for oxygen.
May 17, 2020 · Staphylococcus aureus is a gram-positive, round (coccus) bacteria found in grape-like (staphylo) clusters; opportunistic colonies cause extreme harm. Staphylococcus aureus is, in limited populations, a commensal bacterium that neither harms nor helps the body.
May 23, 2023 · Staphylococcus aureus, one of the more than 36 species in the genus Staphylococcus, is a Gram-positive spherical bacterium of about 0.5–1.5 μm (Fig. 1.1) of diameter which usually grows in grape-like clusters.
Jul 22, 2023 · The species S. aureus was further distinguished in 1884 by German Physician Friedrich Rosenbach and named on the basis of its unique golden colony morphology. S. aureus is a Gram-positive, non-motile facultative anaerobe. Its cocci-shaped cells grow in ‘grape-like’ clusters and readily form aggregates.
May 20, 2024 · Characteristics. S. aureus, similar to other members of its genus, tends to aggregate into grapelike clusters. The name staphylococcus, in fact, is derived from the Greek words staphulē, meaning “bunch of grapes,” and kokkos, meaning “berry.” The word aureus is Latin and means “golden,” which refers to the bacteria’s pigmentation.
Jul 16, 2021 · S. aureus forms a complex structure of extracellular polymeric biofilm that provides a fully secured and functional environment for the formation of microcolonies, their sustenance and recolonization of sessile cells after its dispersal.
