What type of bacteria are staphylococci?

Staphylococci are a type of bacteria characterized by their ability to form clusters, which resemble a bunch of grapes when viewed under a microscope. These bacteria are often pus-forming and are known to be associated with various infections, including skin infections, respiratory infections, and more serious conditions like sepsis. Their capability to grow in clusters is significant in understanding their biological behavior and pathogenic potential.

While non-pathogenic bacteria do exist, staphylococci can include pathogenic strains that can cause disease. Not all bacteria that reside in soil are staphylococci; thus, identifying them solely by their habitat would be misleading. It's also inaccurate to say that staphylococci only cause skin irritation, as they have a much broader range of potential health impacts. Therefore, the defining characteristic of staphylococci being pus-forming bacteria that grow in clusters accurately captures their identity and relevance in clinical microbiology.
