Rhetorical Precis of “Symbiotic gut microbes modulate human metabolic phenotypes”

In the primary research article “Symbiotic gut microbes modulate human metabolic phenotypes”(2007), Li et al evaluated crucial differences in gut microbiota and across ethnicities, particularly between Chinese and American Individuals. The article provides evidence from both human gut samples and non-human gut samples supporting the theory that environment, diet, and genetics have important influences on gut microbiota presence and diversity; thus serving evident to the concept of functional metagenomics. The purpose of Li et al’s article was to demonstrate the promise of gut microbial evaluation in order to improve our contemporary understanding of human health and overall epidemiological susceptibility. This study is directed towards those interested in studying ways to become more critical in regards to genomic medicine approaches with gut microbial presence.

Non-Infectious Diseases #1

When I think of non-infectious diseases that are influenced by microorganisms, I usually think about chronic diseases such as that of the digestive tract, cancer, or of the nervous system. There are so many that I don’t know where I could stop naming them all. I am most interested in the nervous system, so a majority of my posts will probably be linking what we are learning to aspects of that. It will be difficult, as the nervous system does not interact with microbes as frequently as other bodily systems, but I think it will make it more engaging for me to write about.

There are many non-infectious diseases of the nervous system. It would actually be more challenging to list diseases of the nervous system that are infectious, such as the dreaded, infamous meningococcal disease. For the most part, I think of Alzheimers, Parkinsons, Brain Cancer, and Multiple Sclerosis.

A question I would have for my classmates or professor would be if genetic disorders would be classified as infectious. It cannot be easily transmitted to those around us, but it can be transmitted to our offspring? The likelihood of it being transferred is dependent on the gene allele and dominance itself, but I was curious if the criteria are more specific than my understanding.
