A fresh graduate

You don't plan to work in a lab?

Do you just want to teach others from books?

First of all, congratulations on your achievement!

But I'm with osso - without lab work, what are the options for a person with an MS in Microbiology? Apart from a professorship, I would imagine you could go to medical school, but if you haven't gone yet, I suspect you wouldn't be interested now. Nursing school? Branch off into another scientific field like Botany? Go the PhD route and then revisit this question in a few years?

What does your gut tell you?

I responded too fast - I've a microbiology degree and was brought up short by your planning question. I had a six months internship at Scripps Clinic, then an offshoot of Scripps Institute, this in the mid sixties. Then was hired to run an immunology lab.. all by myself, within a med center department at my beck and call. Things progressed and I was happy with where I worked and the people I worked with, but wanted to change fields when I found I was keen on both architecture and landscape, decades later.

I don't regret any of that, I like knowing a bunch in both fields. Sort of a team brain in the works. By my age now, I'm losing track of the old details, but still interested.

Seems you're at loose ends - not sure if you want to continue being a student but unaware of what else you might do. Suggest you pursue employment - get a job, work for a while and decide. There are jobs for microbiologists from government (CDC, FDA, EPA, state health labs) to companies (from Sherwin Williams paint Bristol Meyers Squib pharma) to testing labs.
