The Effect of Chemical Compounds on Smartphone Surface-Isolated Bacteria

Abstract

Cell phones are commonly used in many places for rapid communication within the community. Concerns have been increased about the use of these devices in hospitals, as they can be used everywhere. This research identifies the inhibitory activity of some chemical compounds (methylene blue and malachite green) on bacteria isolated from mobile phone displays. 218 mobile phone samples were compiled and tested from the Department of Pathological Analysis in the collage of Science from September 2018 to April 2019. It was discovered from the scientific analyzes that bacteria found in laboratories were not completely different from the bacteria found in the smartphone displays of students. Only 100 mobile phones showed positive isolation (they were carrying bacteria). The findings of this study indicate that the antibiotic resistance proportion of Gentamycin was 100%, whereas that of Carbenicillin and Piperacillin was 54.5%. For the results of the inhibitory effect of the chemical solutions, methylene blue and malachite green staining had a higher inhibitory effect on Klebsiella sp., whereas 5% methylene blue and malachite green staining had a lower inhibitory effect on Enterobacter sp.. Furthermore, malachite green staining had a significant inhibitory effect on the genus Morganella sp. and Shigella sp., and methylene blue staining had a higher inhibitory effect on the genus Salmonella sp., whereas 10% methylene blue and malachite green staining had a lower inhibitory effect on Klebsiella sp.This implies that it is essential to sanitize hands that have been used to osculate telephones, which represent a wellspring for transmitting microbes.
