Good things about bacteria

A new study shows that tobacco kills the good bacteria in the mouth.

A recent study showed that smoking had a tendency to kill good bacteria in the mouth, making it vulnerable to an invasion by harmful bacteria.

Bacteria begin to appear within a few hours after birth, and the good bacteria help keep bad bacteria at bay.

The mouth of a healthy person contains many bacteria, the majority of, which are beneficial and their number is limited by a regular tooth brushing and flossing.
However, the mouth of a smoker has a different ecosystem and is more likely to be invaded by harmful bacteria. It is well known that smokers have higher rates of oral diseases than non-smokers and an investigation at various stages is in progress, The Ohio State University, and on the role played by microbial communities of the body in the prevention of oral diseases.

According to Purmina Kumor, assistant professor for periodontal energy to Ohio State University ', it is likely that the mouth of a smoker removes the good bacteria to allow bad bacteria to proliferate much faster than non-smokers.

The research team studied how the bacteria began to re-grow after being eliminated by a comparison of 15 smokers and 15 nonsmokers.

Each subject was made clean the mouth by a professional then; researchers took samples of biofilm on the day-after cleaning, then 2, 4 and seven days after.
Biofilms are communities of bacteria that can be harmful or not.

The researchers wanted to see bacteria and auusi study the reaction of the body of the subjects observed.
a good bacteria example
If the body believes the bacteria were harmful, then the sample had a higher rate of cytokines, which are produced by the body to help fight against infection.
Research has highlighted an interesting difference to the fact that the bacterial communities of non-smokers were identical to those present before cleaning professional.

Harmful bacteria were small with a low rate of cytokines, because the body did not need to fight against infection.

Samples of smokers reported that their mouth was colonized by the same level of harmful bacteria on the next day by a professional cleaning, and they had higher levels of cytokine. This indicated that the body was trying to fight against infection.

The study revealed something far more interesting: the bodies of smokers also trying to fight the good bacteria because, for some reason, the good bacteria were considered threats.

The study concludes it is likely that tobacco scrambles the communication between the good bacteria and mouth, some do not facilitate the maintenance of a healthy mouth for smokers.

Whatever the reason, the study highlights the real risks presented by tobacco.
Therefore, any oral disease should be treated further aggressively because of the high risk of harmful bacteria, which occur more quickly.

The problem is that few dentists tell their patients the need to stop smoking, and it depends on the indivudu if he wants to get rid of this habit, although the 'NHS' gives lots of advice, and it is worth taking a look.
