Bacterial passion

The kisses are one of the most representative romantic and passionate samples of the couples , capaza to exchange energy and love, but there is something beyond. Have you ever wondered how many bacteria they are transmitted in a kiss ?

The answer, according to a recent investigation published by the magazine Microbiome , is that during a kiss of 10 seconds are transmitted 80 million bacteria .

 

The intimate kiss, which implies complete contact with the tongue and the exchange of saliva, seems to be courtship behavior unique to humans and is common in more than 90% of known cultures, "he says. Remco Kort , author of the study.

 

Bacterial passion

Researchers of the Organization of Applied Scientific Research (TNO) in the Netherlands, they asked 21 couples that they answered a questionnaire about their habits Kisses , including the frequency with which they gave an "intimate" one; They also gave samples of their tongue and saliva.

With the samples the researchers analyzed the exact composition of the microbiata of each participant. Their results indicate that the more a couple kissed intimately, the more similar their communities were bacteria .

 

The usual explanations of the role played by kissing among humans usually assign a very important role to the microbial present in the oral cavity, although the exact effects of those kisses have never been studied, "explains Kort.

On average, they detected that at least nine Kisses intimate per day caused couples to significantly share their microbiota salivary.

On the other hand, in a controlled experiment of Kisses to quantify the transfer of bacteria , one of the members of each pair drank a probiotic yogurt, which contains specific varieties of these, includingLactobacillus  YBifidobacteria.

Afterwards, the participants offered an "intimate kiss"; When analyzing the recipient's saliva, the researchers found that their amount of bacteria probiotics tripled and the calculation reveals that in a kiss of ten seconds, a total of 80 million of them were transferred.

 

A French kiss is a great example of exposure to a gigantic number of bacteria in a short period of time, "says the study's lead author.

Now that you know how many bacteria they are transmitted in a kiss , you may want to pay a little more attention to your dietary habits and personal care, factors that also play an important role in the oral microbiata , as the research also points out.
