Staphylococcus vs Streptococcus- 20 Major Differences


Staphylococcus and Streptococcus are two genera of bacteria that belong to the phylum Firmicutes, which are characterized by having a thick layer of peptidoglycan in their cell wall. They are also Gram-positive, meaning that they retain the purple dye when stained with Gram stain, a technique used to classify bacteria based on their cell wall structure.

Staphylococcus and Streptococcus are both pathogenic cocci, which are spherical or oval-shaped bacteria that can cause various infections in humans and animals. They are among the most common causes of bacterial diseases worldwide, affecting different parts of the body such as the skin, respiratory tract, urinary tract, blood, and nervous system.
