THE IMPACT OF EXPOSURE TO ELECTRIC AND TOBACCO CIGARETTE SMOKE ON THE GROWTH OF STREPTOCOCCUS PNEUMONIAE, KLEBSIELLA PNEUMONIAE AND MYCOBACTERIUM TUBERCULOSIS IN VITRO, A PRELIMINARY STUDY

Abstract

Consumption of electric cigarettes (e-cigar) in various countries continues to increase every year. The results of research on the impact of exposure to e-cigar smoke produce varied information. The prevalence and severity of Pneumonia and Tuberculosis are influenced by smoking of tobacco cigarettes (tcigar). This study aims to test the effect of e-cigar and t-cigar smoke exposure on the growth of S. pneumoniae, K. pneumoniae and M. tuberculosis in vitro. A descriptive experiment was conducted using three different types of bacteria. The treatment was exposure of e-cigar and t-cigar smoke, as well as no exposure of the both smoke as a control. Power of inhibition e-cigar and t-cigar were calculated using Poisoned food method. The growth of S. pneumoniae is more responsive to exposure to cigarette smoke (e-cigar and t-cigar). In the control group, S. pnemoniae colonies were smaller than K. pnemoniae. E-cigar and t-cigar smoke inhibit the growth of S. pneumoniae and K. pneumoniae, but e-cigar smoke showed more significant inhibition than t-cigar smoke. Further in vivo research is still needed to analyse the impact of e-cigar smoke exposure on human health.
