I read an article called "Are
We Aware of Microbial Hotspots in Our Household?" from the Journal of
Environmental Health, and I tried to gather some questions that were
related to this particular journal article. The topic being researched was the
levels of microorganisms at home, and improper steps to sterilize hotspots that
are overlooked due to neglect of certain areas. The hypothesis, in my own
words, stated “The levels of microbes on household items and personal items
based on different parameters such as type of surface, frequency of cleaning,
type of cleaning agents, and method of cleaning.”
In summary, the article explained
how the general population had misconceptions about the most contaminated
objects in the household and study twenty six objects in twenty two households
in Michigan. Their approach included, also, the data recorded by surface area,
surface type, cleaning frequency of area, type of cleaning agent used, and type
of cleaning to each object.
The study, in conclusion, showed
levels of coliforms, E. coli, yeast, mold, and Staphylococcus aureus (S.aureus)
in the kitchen sponge were higher then in the toothbrush holder. In other words, the
information from the study should show the overall public and help make an
educated decision in developing a proper and routine cleaning regime in their
homes
Here are some questions that I
came up with to relate to the project.
- What is the growth rate of one microbe sample of millions of species?
- The observations of bacteria using some type of media on an object used above.
