Which type of bacteria is characterized by forming pus and is shaped like a string of beads?

The type of bacteria that is characterized by forming pus and is shaped like a string of beads is known as streptococci. Streptococci are spherical in shape and typically arrange themselves in chains or pairs, resembling a string of beads. This arrangement allows them to be easily identified under a microscope. They are known to be responsible for various infections, including strep throat and skin infections, which often produce pus as part of the body’s immune response to infection.

In contrast, staphylococci, which are sometimes confused with streptococci, form clusters or bunches that resemble grapes rather than strings. Bacilli are rod-shaped bacteria and spirilla have a spiral shape. These differences in shape and arrangement are vital for identifying various bacteria and understanding their potential effects on human health.
