Question

What bacteria is this? What's the process of finding it? Negative Stain Gram Stain <

Answer 1

This is gram positive bacteria. Blood agar is a type of differential media which helps to grow such bacteria that are difficult to grow in normal media. Thus it is also called differential media. This differential media doesn't allow the growth of gram negative bacteria. So, the only bacteria which are growing must be gram positive bacteria.

It is gram positive bacteria because gram staining gives positive result for gram positive bacteria. Crystal violet stained bacterial colonies are observed.
