11 Σεπ 2007 · In this prospective study, we found that two-thirds of hospitalized patients harboring S. aureus had intestinal colonization with these organisms. Of the 26 study patients with S. aureus in stool, 20 (77%) had persistent stool carriage and 23 (88%) had concurrent nares carriage.
17 Ιουλ 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).
Staphylococci are gram-positive aerobic organisms. Staphylococcus aureus is the most pathogenic; it typically causes skin infections and sometimes pneumonia, endocarditis, and osteomyelitis. It commonly leads to abscess formation.
Staphylococcus is a genus of Gram-positive bacteria known for their spherical or grape-like clustered shape under a microscope. They are commonly found in various environments, including on the skin and mucous membranes of humans and animals.
Bacteria in the genus Staphylococcus are pathogens of man and other mammals. Traditionally they were divided into two groups on the basis of their ability to clot blood plasma (the coagulase reaction). The coagulase-positive staphylococci constitute the most pathogenic species S aureus.
Staphylococcus aureus infections range from mild to life threatening. The most common staphylococcal infections are. However, the bacteria can travel through the bloodstream (called bacteremia) and infect almost any site in the body, particularly heart valves (endocarditis) and bones (osteomyelitis).
20 Μαρ 2018 · The objectives of this study were to determine the prevalence of S. aureus and MRSA in human stool samples at a large university hospital, to characterize the identified isolates by molecular methods, and to assess potential risk factors for intestinal carriage.
