Apr 15, 2024 · Staphylococcus aureus (staph) is a bacterium commonly found on the skin and in the nose of about 30% of individuals. Most of the time staph does not cause any harm, but it can sometimes cause infections. In healthcare settings, infections can lead to serious or fatal outcomes.
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. [1] .
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).

Signs and symptoms of staph infections vary widely, depending on the location and severity of the infection.
Jun 7, 2022 · Staphylococcal infections, commonly called staph infections, are caused by a genus of bacteria called Staphylococcus. There are more than 30 strains (types) of Staphylococcus bacteria. The most common human pathogen is Staphylococcus aureus. A pathogen is an organism that causes disease.
May 20, 2024 · Staphylococcus aureus is a species of bacteria in family Staphylococcaceae that is considered to be one of the most important pathogens occurring in humans and the most dangerous member of the genus Staphylococcus in terms of its ability to cause disease.
May 25, 2022 · Antibiotic-resistant strains of staph bacteria are often described as methicillin-resistant Staphylococcus aureus (MRSA) strains. The increase in antibiotic-resistant strains has led to the use of IV antibiotics, such as vancomycin or daptomycin, with the potential for more side effects.
Apr 11, 2024 · Key points. MRSA is a type of bacteria that is resistant to several antibiotics. Although anyone can get MRSA, some groups have a higher risk. If left untreated, MRSA infections can cause sepsis or death.
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.
