Perbedaan Jumlah Bakteri Staphylococcus aureus Pada Swab Tenggorok Perokok Aktif dan Non-Perokok di Kelurahan Selayang Kecamatan Medan Selayang

Abstract

Staphylococcus aureus is a gram-positive bacterium, facultative anaerobic, producing yellow pigment in cocci form, with a diameter of 0.5-1.5 μm, arranged like grapes, catalase positive and found singly or in pairs. This bacterium can cause infections in the oral cavity with characteristic signs such as inflammation, necrosis, and abscess formation. Staphylococcus aureus also has the ability to form biofilms on tooth surfaces, making it difficult to kill with standard antibiotics. This results in chronic infections such as endocarditis, osteomyelitis, and the formation of pus pockets or abscesses. Staphylococcus aureus can spread through the blood vessels, causing abscesses in the lungs and bones. People who smoke cigarettes regularly exhale smoke and affect others, especially those aged 10-18 years, increasing from 7.2% to 9.1%. Active smokers are exposed to more genotoxic substances than passive smokers. In several studies, active smokers with throat swabs can be isolated from Staphylococcus aureus bacteria. Purpose of the study to determine the number of Staphylococcus aureus bacterial colonies and the difference in the number of Staphylococcus aureus bacterial colonies in throat swabs of active and non-smokers in Selayang Village, Medan Selayang District. Method this study used descriptive observational research with a cross-sectional approach, presented in tabular form and analyzed. Results of the study showed that there are 100% of 10 Staphylococcus aureus bacteria in active smokers, the average number of colonies is 120 with the highest number of colonies PA2 183 colonies and the lowest PA3 with 69 colonies and in non-smokers 60% with an average number of colonies of 25 colonies in non-smokers the highest number of colonies is NP1 with 48 colonies and the lowest is NP9 with 14 colonies. Other bacteria that could be isolated were Streptococcus sp., Klebsiella pneumoniae, Staphylococcus warneri, Kocuria kristinae, Staphylococcus hominis and Staphylococcus lentus. Conclusion is that there is a difference in the number of Staphylococcus aureus bacterial colonies in active smokers and non-smokers.
