Staphylococcus aureus is, in limited populations, a commensal bacterium that neither harms nor helps the body. Other staphylococci, including S epidermidis, are considered commensals, or normal inhabitants of the skin surface. Secretions are numerous, but include surface associated adhesins, exoenzymes, and capsular polysaccharides. While these germs dont always cause harm, they can make you sick under the right circumstances.
Other types of staph, particularly Staphylococcus aureus, can cause serious infections. People who carry the bacteria Staphylococcus aureus (Staph), which is commonly found on the skin, can contaminate food if they don't wash their hands before touching it.

One such event has been occurring in China since 2013, with community-associated (CA-MRSA) strains Staph that cant be cured by one group of common antibiotics is called MRSA (methicillin-resistant Staphylococcus aureus). What is MRSA? Staphylococcus aureus is a gram-positive bacteria, which means that the cell wall of this bacteria consists of a very thick peptidoglycan layer. Staphylococci (staph) are a common type of bacteria that live on the skin and mucous membranes (for example, in the nostrils) of humans. On this page. Infections caused by this pathogen are common both in community-acquired and hospital-acquired settings. It stains Gram positive and is non-moving small round shaped or non-motile cocci. 1.

"Staph," or staphylococcus, is a type of bacteria that naturally exist in the environment, including on people's skin. Some types of staph normally live on people's skin and in the environment and don't cause disease. A bacterial common species found especially on nasal mucous membranes and skin (hair follicles); it causes furunculosis, cellulitis, pyemia, pneumonia, osteomyelitis, endocarditis, suppuration of wounds, other infections, and food poisoning; also a cause of infection in burn patients. 3. Mild to life-threatening sepsis can occur if the organism enters into the body especially in an immunocompromised or immunosuppressed individual. A type called Staphylococcus aureus causes most infections. More recently it has been shown that S. aureus can passively move across agar surfaces in a process called spreading. Other types of staph, particularly Staphylococcus aureus, can cause serious infections. Staphylococcus aureus is currently the most common cause of SSIs causing as many as 37% of cases of SSIs in community hospitals with methicillin-resistant S. aureus (MRSA) of particular concern.
