A kiss can spread more bacteria than love, here's how

New Delhi: Here is a piece of news worth noting for the couples as a new study suggests that kissing even for 10 seconds can transfer as many as 80 million bacteria. Shocking! Isn't it? And you thought a kiss only spreads love.

So, think twice before kissing next time as according to researchers, close physical contact during kissing involves full tongue contact and saliva exchange which leads to transfer of dangerous bacteria.

Along with researchers from Micropia - the world's first museum on microbes - in Amsterdam, Kort studied 21 couples, asking them to fill out questionnaires on their kissing behaviour including their average intimate kiss frequency.

In a controlled kissing experiment to quantify the transfer of bacteria, a member of each of the couples had a probiotic drink containing specific varieties of bacteria.

After an intimate kiss, researchers found that the quantity of probiotic bacteria in the receiver's saliva rose threefold.

They calculated that in total, 80 million bacteria would have been transferred during a 10-second kiss.

On an average, it was found that partners who kissed each other at least nine times a day shared similar communities of oral bacteria.

The study also suggests an important role for other mechanisms that select oral microbiota, resulting from a shared lifestyle, dietary and personal care habits.

The ecosystem of more than 100 trillion microorganisms that live in our bodies - the microbiome - is essential for the digestion of food, synthesizing nutrients, and preventing disease.

It is shaped by genetics, diet and age, but also the individuals with whom we interact.

With the mouth playing host to more than 700 varieties of bacteria, the oral microbiota also appear to be influenced by those closest to us.

The research was published in the open access journal Microbiome.
