Research: which harm of e-cigarettes and traditional cigarettes will make lung bacteria more "toxic"

The study also found that exposure to cigarette smoke or e-cigarette steam had similar effects on the behavior and pathogenicity of pathogenic bacteria. "These findings suggest that the effect of e-cigarettes on common lung pathogens may be similar to that of cigarettes," Gilpin said

The team further observed the bacterial infection of human lung cells when exposed to cigarette smoke or e-cigarette steam extract. The results showed that the amount of interleukin-8, an inflammation related factor secreted by these cells, also increased.

However, the research team also said that they used a common brand of e-cigarette in their research. The top ten famous e-cigarette brands have no additional taste. Bacteria will only be exposed once in cigarette smoke or e-cigarette steam extract. It is necessary to further investigate the impact of aroma substances in e-cigarette. (reporter Zhang Jiawei)

A new study released by Queen's University of Belfast, UK, shows that e-cigarette steam is the same as the smoke of traditional cigarettes. Is e-cigarette oil toxic? It will enhance the pathogenicity of some lung pathogens, which is conducive to the formation of stubborn infections such as chronic obstructive pulmonary disease and asthma.

The corresponding author of the paper, Dr. Dale Gilpin of the University, said that many lung diseases are closely related to pathogenic bacteria. This study compared the effects of e-cigarette steam and cigarette smoke on major lung pathogens for the first time. The research results have been published in the international journal respiratory research.

The researchers exposed Haemophilus influenzae, Streptococcus pneumoniae, Staphylococcus aureus and Pseudomonas aeruginosa to traditional cigarette smoke or e-cigarette steam extract for culture, and found that the biofilm formed by these bacteria increased. Biofilm is an aggregate of one or more microorganisms, which will form and grow during microbial infection.
