What characterizes staphylococci?

Staphylococci are best characterized as pus-forming bacteria that grow in clusters. This description is significant because staphylococci, particularly Staphylococcus aureus, are known for their ability to cause various infections, including skin infections, pneumonia, and food poisoning, among others. The characteristic cluster formation is similar to a bunch of grapes when viewed under a microscope, which is a distinctive feature of these bacteria. Their ability to produce pus indicates an inflammatory response, typically associated with infections.

This understanding is crucial for estheticians, as they need to be aware of potential bacterial skin infections that can arise during treatments. Knowledge of staphylococci is vital in maintaining hygiene and minimizing the risk of infection in clients. The other descriptions do not accurately capture the defining traits of staphylococci.
