Researchers at the University of Maryland investigated the bacterial metagenomics of four brands of cigarettes and detected 15 classes of bacteria in all cigarette samples. Holy Smoke! (couldn't resist) The research by
Saplota et al, just published in the March 2010 issue of Environmental Health Perspectives, found
Acinetobacter, Bacillus, Burkholderia, Clostridium, Klebsiella, Pseudomonas aeruginosa, and
Serratia in ≥ 90% of all cigarette samples and also
Campylobacter, Enterococcus, Proteus, and Staphylococcus.
The authors point out that earlier studies had found some of these same bacteria on fresh tobacco leaves suggesting that contamination might be occurring at the farm or production level. Other data has shown that certain bacteria,
M. avium, can survive the burning/smoking process and infect the lungs. Perhaps this suggests that some other organisms (e.g.
Bacillus or
Clostridium) might also be able to survive. Of course more research is needed. Fascinating stuff and isn't it great to know that in this age of instant access to information, that it only took me 9 months to find this study!
