What type of bacteria causes staph infections?

Staphylococcus aureus is the correct answer as it is the specific type of bacteria that causes staph infections. This bacterium is commonly found on the skin and in the nasal passages of healthy individuals. While it may not always cause harm, it can lead to various infections, ranging from minor skin infections to more serious conditions such as pneumonia, bloodstream infections, and surgical site infections when it enters the body through cuts or other openings.

Understanding that Staphylococcus aureus is a part of the normal flora, but can become pathogenic under certain conditions, is important in both treatment and prevention of infections. Awareness of this bacteria helps in recognizing its potential risks in cosmetology practices, particularly when it comes to maintaining skin integrity and hygiene standards.
