What type of pus-forming bacteria grows in clusters resembling grapes?

The type of pus-forming bacteria that grows in clusters resembling grapes is Staphylococci. This genus is characterized by its arrangement of cells, which typically appear in clusters or bunches, much like grapes. Staphylococci are known for being opportunistic pathogens, which means they can cause a variety of infections, particularly when they enter the body through broken skin or other vulnerabilities.

The structure and growth pattern of Staphylococci contribute to their identification in laboratory settings, distinguishing them from other bacterial forms. For instance, Streptococci are typically found in chains, Bacilli are rod-shaped bacteria that can appear singly or in chains, and Diplococci appear as pairs. This morphological characteristic plays a critical role in understanding microbial classifications and their implications in health and disease.
