The Analysis of Staphylococcus aureus Bacteria after Exposure to Electromagnetic Radiation via Support Vector Machine

摘要

Microbiology is a field that is explored by many biomedical practitioners and other professionals coming from different fields. It deals with microorganisms that are too tiny to be recognized by the human eyes. Staphylococcus aureus is a microorganism considered as a major bacterial human pathogen. It is found on the skin and mucous membranes which causes a wide variety of diseases like bacteremia, infective endocarditis, skin and soft tissue infections. Several studies showed that inhibitory effect of GHz and mobile phone electromagnetic radiation to microorganisms exists. In this research, Staphylococcus aureus were exposed to electromagnetic radiation with frequency of 880MHz which is within Ultra High Frequency (UFH) range. After incubation, the images of the bacterial colonies were captured and analyzed using the algorithm in Matlab which is the Support Vector Machine (SVM). Simulation results showed that from the exposed sample, there were 1,081 colonies. From the unexposed sample, 1,190 colonies were found. These results show inhibitory effect of the electromagnetic radiation to Staphylococcus aureus. This outcome can be used in exploring other applications of electromagnetic radiation and the use of image processing in microbiology and broaden applications of machine learning.
