Writing Exercise #6

I have never personally taken antibiotics but I would if required. When a physician instructs the administration of antibiotics they believe the benefits outweigh the side effects that could be involved. The majority of the time the issue antibiotics are needed for is of a much greater concern than some small side effects that may make you uncomfortable. I have also learned enough through my time in college to know that antibiotics have real science behind them and should always be considered when health issues are present.

Writing Exercise 5

Multiple things in our daily lives can change our gut microbial community. It can be anywhere from the food we eat, the things we touch throughout the day, our stress levels and also medicine we use. Many people are very self conscious of what they put in their body but that is definitely not me. I barely eat vegetables and consume mostly meats and carbohydrates. This lack of variety could have a harmful effect on my gut community. I am also around dogs that play outside quite frequently. This has the potential for me to introduce new bacterial species into my gut after a good hour of playing with them. This may cause issues but its well worth it for some good stress relieving dog wrestling. Another part of my life that I know effects my gut microbial community is the Proton-Pump inhibitors I take to reduce acid build up. There’s bound to be hundreds of things one does in their life that can effect the gut microbial community.

Behaviors that could change the gut microbial community in humans:

Eating more walnuts– It has been shown that walnuts have a specific set of nutrients and fibers that have the ability to alter the gut microbial community. These changes include an increase in diversity and a more even spread between bacterial species. This has an overall positive effect on the health of the individual,

Close contact with sheep- When livestock animals are gathered together in small areas and an individual perhaps touches one of them and then goes and eats food without washing bacteria can be transferred. One common bacteria in this case is E. coli which is very harmful to the health of the individual.

Eating yogurt- Yogurt is a source of probiotics which introduce bacteria into the gut. These are considered good microbes which assist in keeping digestive functions healthy.

Writing Exercise #3

Based on this weeks reading of “Viruses and Human Cancer: From Detection to Causality” by Sarid and Gao I feel the HPV types to be covered in a new treatment should be 31 and 45. I make this decision based on two thing discussed in the paper. the first being there are four strains that are seen as the most dangerous and of those four the two other than 31 and 45 have vaccines already in circulation. The second reason for making this decision is if new research and treatments are being covered it should consist of these two that account for the majority of cervical cancer. By restricting new treatment research to two types more progress can be made saving money and at the same time having a great decrease on cancer rates. For when this new treatment should be administered it should relate to when it will be most effective. Since HPV is a virus, vaccines are the most effective method and should be given before a patient comes into contact with HPV. Considering HPV is spread through sexual means it would make since to give the vaccines prior to when individuals become sexually active.

In the article “Symbiotic gut microbes modulate human metabolic phenotypes” (2007) Min Li et al showed that there is a correlation between specific microbe species in the human gut and metabolic phenotypes that can affect human health. To support this Li et al studied Chinese individuals gut microbial makeup using the noninvasively obtained excreted metabolite profile and fecal microbiotal composition to find differences in the ratios of bacteria. The purpose of this study was to find new ways to relate gut microbes to human metabolic phenotypes in order to accomplish this new methods were used to compare different individuals. This article can be used by other professionals in the field to direct their research and to have a better understanding of the relationship between specific microorganisms and human hosts.

Different types of non-infectious diseases influenced by microorganisms in the human body (a list):
Celiac disease
Crohn’s disease

These diseases may be non-infectious but they are caused by certain infectious diseases. Microbes cause infectious diseases and anywhere from a month to many years later the non-infectious diseases(listed above) may appear.
