Part 4/7:
The most commonly found bacteria in the samples was Staphylococcus aureus. This bacterium, commonly associated with skin infections, was present in significant quantities in many of the sponges examined. Its presence indicates that we are inadvertently transferring skin bacteria onto our sponges during regular use. The abundance of Staphylococcus aureus suggests that bacteria from our skin are easily left behind, further fueling microbial proliferation.
