Cigarette smoking has known health risks regarding respiratory tract infections and may increase biofilm production in causal bacterial pathogens. With the advent of electronic cigarettes, more potent modern cigarettes, and increased bacterial resistance to antimicrobial therapies, it is crucial to the medical research community to study how bacteria are impacted by cigarette smoke exposure. Using Pseudomonas aeruginosa and Pseudomonas fluorescens as model organisms, this study is to investigate how cigarette smoke extract affects biofilm formation. Both electronic and traditional smoke extract were seen to upregulate biofilm production in the pathogenic bacteria Staphylococcus aureus, however, there were no statistical differences in the quantity of biofilm produced. The study also serves to investigate if electronic cigarettes or traditional cigarettes are able to affect biofilm production to different extents, contrary to most studies. This study will test the extent of biofilm production for Pseudomonas aeruginosa and Pseudomonas fluorescens subjected to Electronic and traditional cigarette smoke extract.
