The debate weighing up the relative harms and benefits of e-cigarettes continues. New evidence suggests that e-cigarettes boost the virulence of drug-resistant pathogens, according to researchers at the VA San Diego Healthcare System and the University of California, San Diego.

Dr. Crotty Alexander and her team grew methicillin-resistant Staphylococcus aureus (MRSA) in culture. They found that exposing the MRSA to e-cigarette vapor - similar in concentration to e-cigarette products available on the market - increased the virulence of the bacteria, making it better able to establish infection in the body and cause more severe disease.

The e-cigarette vapor caused alterations in the surface charge and biofilm formation of the MRSA, which provided greater resistance to attack from human cells and antibiotics.
The surface of the bacteria became more positively charged to avoid binding by the animicrobial peptides that are lethal to the pathogen. The bacterial biofilms also became thicker, making the MRSA less vulnerable to attack.
Another possible factor in the increased resistance of the MRSA was a change in pH, which jumped from 7.4 up to 8.4 when exposed to the e-cigarette vapor. This change in pH makes the environment very alkalotic, which stresses the MRSA cells and prompts activation of defense mechanisms.
:snip:
Although the e-cigarette vapor increased the resistance of this pathogen, which is potentially lethal to humans, the virulence of MRSA was even greater when exposed to conventional cigarette smoke.
The surface charge alterations in the bacteria were 10 times greater when exposed to conventional cigarette smoke, compared with e-cigarette vapor.

Abortions increase a woman’s chances of getting breast cancer, but they’ll never touch that one.

I got mine from a specialty store. I tried their weakest mixture, and still just coughed my gutz out! Didn’t try one of the flavored types though.
The Halo flavor Kringle’s Curse is pure peppermint goodness and not the slightest harsh. They have a good tank and battery system as well.
They also cause climate change and white privilege.
So the alkalinity alone increased resistance? Heat, nicotine, water vapor?
My wife had smoked cigarettes for over 35 years.
Within a month of starting e-cigarettes, she had weaned herself off nicotine. She continued to use the e-cigs for several months to feed her oral fixation but eventually she quit them altogether.
She had tried everything, including Chantix. Nothing worked until the e-cigarettes came along.
The people that are out to restrict the use of electronic cigarettes are most likely doing the bidding of Big Pharmacy in order to clear the decks for their product.
Does it really F'n matter???? If they want you to stop enjoying whatever vices you may have, they'll find a study to justify it.........It's all just bullshit.......
I didn’t get it either. If it’s salinity, then what about people who frequent the seashore and breathe in salt spray on a regular basis?
Leading cause of Staphylococcus infection is being at the hospital. Stay home and have a smoke and you’ll be much better off.
