Is Staphylococcus aureus considered a multicellular organism or a single celled organism?

Question

I wanted to know if it is considered multicellular since it lives in clusters of other cells. I also wanted to know what intracellular structures impact the function of the cell. Also, does the cell undergo differentiation? Thank you for any help!

Answer 1

single celled.

it can differentiate from planktonic (normal, free floating cells) into biofilms which are adherent multi-cellular structured communities that attach to various surfaces.


edit: added a source, reworded the development statement to make it more clear.

Answer 2

First: Staphylococcus aureus is a kind of Staphylococci bacteria that divide in multiples, "from staphyle, the Greek word for grape", Staphylococcus aureus is a wide food poisoning bacteria as well as numerous skin infections, which is known as "Staph" infection.
Last: In my opinion most bacteria do not differentiate as it reproduce asexually, thus the daughter cell is the same as the mother cell. That's why diferentiation is not very clear in bacterial cells.
And I can't get your second question!!!

Answer 3

I believe S. aureus is a single celled organism. It just likes to live in colonies. One cell though can reproduce to form that colony. I'm not entirely sure on the intracellular structures, outside of proteins that the cells use to attach to each other and their hosts. I do not belive it undergoes differentiation.
