If I was put in a quarantine bubble and the only germs/viruses in the bubble were in or on my body, could I get sick?

Assuming I could keep living without any food/water, could I get a sickness related to the germs or viruses in my body? I am not counting genetic diseases.

Yes. 

If you get stressed and have had previous exposure to herpesviruses (HSV1, HSV2, VZV, etc) you can get flare-ups of those diseases. 

As you get older, your immune system declines in capability as well, so normal bacterial flora can cause problems. Even if your immune system doesn't lose competence, If you don't remain sanitary, you could get a UTI from your colonic bacterial flora. You could scratch yourself accidentally and the anaerobic flora on your skin could infect the scratch wound.
