In chapter 5, I learned that an adult human contains ten times as many foreign microbial cells as mammalian cells. I also learned a lot about host manipulation in animals from spiders to humans. I found it really intriguing that the cold virus actually triggers your sneezing reflex so that it can infect others around you. Other viruses, such as cholera and some STDs, also use various degrees of host manipulation to find transmission channels. I also found it interesting that our sense of disgust at certain smells that have a load of infectious material, such as spoiled food, really helps us avoid infection. Additionally, a human’s fear of strangers (xenophobia) might be due to the instinctive avoidance of disease. A key point in chapter 5 was that the degree of virulence is determined by how a parasite gets from host to host. The final fact I learned in chapter 5 was that anthrax can exist outside a host for over ten years.…

Colonisation is when a microbe finds itself a host and a susceptible environment (for example; skin or an object) and then multiplies. Not necessarily threatening, but you then become the carrier.…
In the other study of Reyniers’ experiment of a bacteria free animal, Dunn introduces the anecdote of the bubble boy. The bubble boy was a child who “had been transferred antiseptically into a chamber at birth because he lacked an immune system” (76). Dunn uses this one instance of the bubble boy to prove that the bubble boy died after reattachment to other germs and bacteria due to his lack of interaction with these species. Together these experiments are anecdotes that Dunn uses as resources to support his other large…
Microbes, despite being the most abundant organisms on Earth, were relatively inconspicuous to humans until the 17th century. These life forms have evolved their mechanisms of growth and survival in order to face the harsh conditions of the planet. While it often seems like two types of microbes, viruses and bacteria, have only impacted human life by increasing the fatality rate, Dorothy H. Crawford’s book, Deadly Companions, refutes this claim. Crawford argues that there are more important effects involved with microbial presence, as they have thrived during specific stages of human cultural history and have had a major impact on previous generations that have become lasting developments. More specifically, microbes have forced humans, the…

The One Health initiative is a change in basic assumptions that focuses on surveillance of the environment, animals, and humans to predict occurrence of an outbreak before it happens. This is important in improving the health of communities because preventative measures will be used and it also makes people aware of what could happen if preventative measures were not taken. Scientists and doctors worldwide collaborate to develop upstream interventions that prevent transmission of pathogens and/or disease. Collaboration is a key to One Health because the three domains work together to better the health of the community. The term One Health makes it known that the three domains; humans, animals, and the environment are all interrelated.…
Immigration is an integral part of the U.S. social fabric. As of 2004, a total of 12 percent of the population was foreign born. Immigrants account for a disproportionate share of population growth because they are younger and have higher fertility rates than natives. Because of immigration’s importance, immigration policy has been debated throughout our history. In the past thirty years, the United States has undergone tremendous changes, yet immigration policy has not changed with the times. With immigration needing reform, requiring such careful attention, no two policies have been more examined then that of open immigration or closed borders.…
Critical Response: In this article, “The Teeming Metropolis of You” by Brendan Buhler, the author gives the reader an insight into the microbiology of our body and gives us a clear explanation of how things function as well. The reader can really get involved into the story because the author gives a lot of reliable facts as examples of how things work in our body. As he writes in the ninth paragraph of his article, “To some extent, this makes sense; after all, if harmless bacteria were playing for keeps, they wouldn’t be harmless—they would be…
