Document Summary
Look at how microbes interact with us in health and disease. Ecological contributions nutrient cycling: decay-bacteria and fungi break down the remains of dead organisms into inorganic nutrients. (decomposition is essential for nutrient cycling), parasites (sometimes a symbiotic relationship between. Normalmicroflora/microbiota: usually community of species associated with different parts of the human body. Variety of bacteria, fungi and protozoa (no viruses: accumulate normal microflora. Average healthy adult accumulates more bacteria than cells. There are many more microbes (fungi, protozoa etc. ) than cells however it does not make us sick, they are just part of the body. )t"s important that babies especially get exposure to microbes for our immune system and microflora as most of them will be harmless.

We don"t want microflora in blood as that would disrupt the circulatory system.
