Staphylococcus Aureus (黄色ブドウ球菌 Ōshokubudōkyūkin?) is a recurring antagonist in Cells at Work!.
She is a type of bacteria that lives on the skin who can cause skin infections, pneumonia, meningitis, septicemia and food poisoning if ingested.
Like other bacteria cells, all Staphylococcus share the same appearance. They have a thin skeletal frame adorned with a spheres that form a grape-like dress based off of when they cluster together like grapes on the vine.
- Grape formation: With other Staphylococcus Aureuses, they form a giant Staphylococcus Aureus. Thus unlocking the ability to use the fibrin to fight the immune cells.
