Presence of Bacteria in University Library

The study assessed the presence of bacteria in the University library. Mainly, the objective of this study was to determine the estimated number of bacteria that is present in a school memorial library. The researchers used the experimental design that focused on conducting bacterial colony count estimates. After performing the biochemical tests, further analysis showed the following results: Both gram positive and negative bacteria were present in stained slides, ranging from cocci to diplococci in chains. After further analysis, the most-common bacteria were narrowed down to two definite species: Escherichia coli and Staphylococcus spp. A factor that may also have contributed to the increase in the bacterial colony count from week two to week three was the increase of the number of students using the library during the final examination week.
