Kind of wondering:

If the sample I'd obtained earlier this week from the saliva and mucus inside my mouth and cultured on a petri dish with some Mitis salivarius agar is going to have its biota composition reflect that I was still sick at the time I'd made it.  That media is designed to show breakdown of dextran I think... so you can use it to culture stuff that eats sugar.

Today professor was explaining to us about the natively endogenous? and transient types of bacteria we can harbor.
I know they can interact with each other and that sometimes when we get sick it is from picking up a pathogenic species that displaces our normal body microbiota altering the makeup.
