What arrangement do streptococci exhibit?

Streptococci are a group of bacteria that are characterized by their unique arrangement when they are viewed under a microscope. They typically exhibit a chain-like formation. This arrangement arises from their method of cell division, which occurs through binary fission, where the daughter cells remain attached to one another after dividing. As a result, streptococci can be recognized by their linear arrangement of cells resembling chains, which distinguishes them from other types of bacteria that may form pairs or clusters. Understanding this characteristic arrangement is important for identifying streptococci in laboratory settings and for diagnosing infections caused by these bacteria.
