Lab Report

The goal of this project is to identify the bacteria from a cellphone and what parts of human body are affected by the bacteria that grow on a cellphone. A cellphone can carry a ton of bacteria, because we take our cellphone everywhere and anywhere, we go. Our hands are one of the reasons for growing a bacterium on the mobile phone, for example, when we use the bathroom and touch something in the bathroom, when we shake someone’s hand, and when grab the doors at school. Sometimes, we don’t realize that we have already transferred the bacteria to our phone after we touch something. Cellphones can get bacteria when we place it on something or when our kids or family member borrow our cellphone. The most common of the bacteria that we could transmit from the phone are Staphylococcus, and Micrococcus.

In the textbook, Staphylococcus, Micrococcus, Pseudomonas, and E. coli. are responsible for multiple common human skin infections. Staphylococcus is a Gram-positive coccus, which is inward-looking pathogen of multiple types that could infect skin wounds with the homogenous symptoms with the combination of a pathogen. Also, the Staphylococcus tolerates a high salt concentration, facultative anaerobes and produce catalase. Under the microscope, Staphylococcus shows spherical and form grape-like cluster. In likewise, Micrococcus is also a Gram-positive coccus and typically shows quadruplet under the microscope. It is nonpathogenic forms that are found everywhere, decaying organic matter and on the human skin.

The article is about cellular phones and the possibility of bacteria growth. This study took 192 mobile phones, 102 from males and 90 from females. It is shown that female had a higher microbial growth than males. There was a definite difference from phones kept in pockets and bags. Phones in pockets had less growth than those
