Blood Agar Usage
Country: United States
Date: April 2006
I have a supply of blood agar. Is this agar Ok in
growing common bacteria?
It is mostly designed to grow animal disease causing germs. I don't suggest
you use it without a scientist's supervision.
Be careful when using blood agar. Most bacteria that cause disease grow
very well on blood agar. If you decide to use it, I would tape the lid to
the plate and observe it through the lid. Use 10% bleach on your work
surfaces before and after you work and soak the plates in bleach before you
dispose of them. Wash your hands before and after you work with them.
As a former middle school teacher and a college level biology instructor, I
really think you should not pursue this project. Blood agar will grow some
very nasty bacteria and unless you are in a microbiology lab and understand
the necessary procedures to maintain a safe environment, I am concerned for
your health. Furthermore, if you do proceed, what about disposal? An
autoclave is necessary to assure safe disposal of bacteria growth.
Reconsider this proposal.
