Microbiology Lab Page 2 Interspecific Interactions Today we know that we live in some protozoa and yeasts. The deep tissues are fairly microorganism-free, with the exception encysting eukaryotic protozoan parasites, but the "outer" coverings of the body are rich in microorganism diversity. In fact there are more bacteria in our intestinal tract than there are cells in our body a symbiotic relationship with microorganisms, primarily bacteria, but also How can that be possible? What are the "outer" coverings? Until fairly recently, scientists considered the microorganisms that live in or on our bodies to be commensal. Commensal organisms are those that benefit from a host species without affecting the host species, either positively or negatively. The idea was that the microorganisms benefited from the environment of our bodies, but our bodies weren't really affected by their presence. Today we know th that is not the case. Our bodies are constantly interacting with our symbiotic bacteria in a variety of wa mutualistic relationship with most of our symbiotic bacteria; we benefit tremendously fr tian of other nathogenic bacteria, and evExplanation / Answer
The human intestine is filled with the bacteria than the cells it have. There are more than 500 species of bacteria found in the human colon that live in the symbiotic relationship. The presence of bacteria in the gut is possible because of their symbiotic relationship. The presence of bacteria in the gut helps the bacteria and human both in their survival. These bacteria neutralize harmful toxins that are the by-products of digestion. The beneficial bacteria discourage the bad bacteria. The bacteria present in the gut also help in completing the demand of vitamins B and K.
The outer coverings of the human body are skin, hair and mucus membrane of the nose. An outer covering acts as a barrier to prevent the entry of microbes into the body. Any breach in the outer coverings can make the microbes to enter into the body.
