What bacteria are known for forming pus and growing in clusters like grapes?

The bacteria known for forming pus and exhibiting growth in clusters that resemble grapes are indeed Staphylococci. This group of bacteria is characterized by their spherical shape and ability to form clusters due to their pattern of division. They thrive in various environments and can be responsible for a range of infections, particularly skin infections, abscesses, and other pus-forming conditions.

Staphylococci's ability to produce pus is often a result of the body's immune response to the infection they cause, leading to the collection of white blood cells and dead bacteria that form pus at the infected site. This is in contrast to other types of bacteria that may not form pus or cluster in a similar manner. Understanding the characteristics of Staphylococci is crucial in the context of infection control, especially for barbers and other professionals who may come into contact with these pathogens in various settings.
