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
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.
