I was wondering if anybody knew of a web-site that may help be find information on how humans can harbor many microorganisms on and inside their bodies without experiencing symptoms of infection thanks for you help

Answer 1

Since this is not my area of expertise, I searched Google under the key words "'human microorganisms'" to get this possible source:

http://www.pharmcast.com/Patents100/Yr2005/Mar2005/032205/6869623_Disinfectant032205.htm

In doing my research, I came across the term, "probiotics." Searching with this key word, I found:

http://en.wikipedia.org/wiki/Probiotic
http://www.medicinenet.com/probiotics/article.htm
http://www.webmd.com/diet/tc/probiotics-topic-overview
http://www.mayoclinic.com/health/probiotics/AN00389

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. Thanks for asking.
