What distinguishes the arrangement of Staphylococci?

Staphylococci are distinctive in that they cluster together, resembling bunches of grapes. This clustering is due to their unique method of division, which occurs in multiple planes, not just in a single plane like streptococci, which tend to form chains. The clustering characteristic helps in identifying staphylococci under the microscope and in differentiating them from other cocci arrangements. This morphological trait is a key identifier for this genus and plays a significant role in microbiological diagnostics.
