Cigarettes are contaminated with bacteria ?
Cigarettes are contaminated with bacteria! There is not a new anti-smoking slogan, but the conclusion of a comprehensive study of French and American researchers. Thus, it draws attention that itself cigarettes may be a cause of diseases with possible fatal effects, due to pathogenic microbial content. Also, experts from the University of Maryland along with those from the Central School of Lyon argue that the danger is as great and if passive smoking, when passive smokers are inhaling contaminated smoke.
Specialists have identified a number of pathogens responsible for the occurrence of infectious diseases. Amy R. Sapkota, chief of the research team that carried out this first study, says that this type of bacteria survived to the combustion process during smoking. Sapkota demanded the international medical community to intensify efforts to stop smoking, a habit of approximately one billion people.
The statistics show that cigarette smoke contains over 4,000 different chemicals, of which over 300 are toxic to humans: nicotine, arsenic, radon, cyanide, phenol, DDT, asbestos, benzene, carbon monoxide, formaldehyde, etc.. and another 43 are carcinogenic. Most toxic compounds are nicotine, tars and carbon monoxide.
Specialists point out that smoking a single cigarette shortens life with 7 minutes and smoking a pack of cigarettes per day shortens the life of 140 minutes per day, 51,100 minutes / year or 35.5 days per year.
According to a new international study conducted by a University of Maryland environmental health researcher and microbial ecologists at the Ecole Centrale de Lyon in France shows that cigarettes are widely contaminated with bacteria, including some known to cause disease in people.
The research team describes the study as the first to show that "cigarettes themselves could be the direct source of exposure to a wide array of potentially pathogenic microbes among smokers and other people exposed to second hand smoke."
The researchers describe the study as the first snapshot of the total population of bacteria in cigarettes. Previous researchers have taken small samples of cigarette tobacco and placed them in cultures to see whether bacteria would grow. But Sapkota's team took a more holistic approach using DNA microarray analysis to estimate the so-called bacterial metagenome.
