What is Microbiology

Microbiology is the study of interaction between microorganisms and their surroundings, such as humans, animals, plants and our environment. (Belisle)

Microorganisms also known as microbes, which are very small organisms that are often too small to be seen with naked eye. Some examples are bacteria, viruses, single celled eukaryotes etc. There are also some microorganisms that are visible to the naked eye, such as fungi and algae. (Belisle)

Why is Microbiology important?

Microbes are everywhere! Microbes are the oldest form of life, and they are the largest group of living material on Earth, (maybe consider virus as an exception). (Microbiology) Every living organisms and our environment rely heavily on bacteria for:

  • health = normal microflora, antibiotics, nutrient production etc.
  • food = beer, wine, milk, cheese etc.
  • high quality grain (industrial agriculture)
  • degradation of nutrients in our environment,
  • and more!

This is only few examples of broad uses of microbes in our lives.

Personally, I believe that our society can become healthier if more people gain knowledge in topics of microbiology, as it would help us:

  • to prevent creating “Superbugs” by not abusing/misusing antibiotics, http://www.cbc.ca/news/health/superbug-ndm-1.3935083 (Jan 31, 2017)
  • to stay healthy by keeping our surroundings clean from potential infections, and by not killing necessary bacteria in and on our body,
  • to appreciate the presence of microbes and learn how to make use of them more efficiently that would give both of us benefits.

All microbes are opportunistic, even the ones that provide us benefits. This means that if we become immunocompromised, our friendly microbes (like S. aureus, E. coli) can also infect us!

Hence, understanding common/basic mechanisms of microbes and knowing how to protect ourselves would definitely benefit our society (reduced hospital cost, increase efficiency in industrial agriculture, production etc).

So, I would like to invite all of you to follow my fun adventure in studying Microbiology, as I will post my study/research notes on this blog.

I am a current Microbiology student, and not an expert. However, I will always try my best to cite my notes with credible sources, so that people can always refer to the original source.

My goal is to teach myself from researching/writing these notes out and improve my writing skills, but also to make things easier for the public to understand and find interest in Microbiology 🙂

Have fun, and see in you next post!
