Those who think that love is theonly thing exchanged with a kiss should think again. The “seal” of the poets is a powerful “vector” for the transmission of bacteria.

What happens during the outpouring of the most romantic and passionate effusion?

The Netherlands Organisation for Applied Scientific Researchsucceeded to count thebacteriajumping from tongue to tongue and published onѾDzdza study that revealed incredible results: 80 million bacteria and 700 different strains are exchanged with each kiss!

No worries, though.It is a gift that is generally harmless.

“In fact – says , Head ofRheumatology and Clinical Immunologyat鶹ýAV߿– if thekissis part of our set of social behaviour from the beginning of time,surely there must be some secret in this evolutionary gesture. There might be an explanation for the exchange ofbacteria.”

“Yet another fact seems to confirm the importance of this factor – the specialist continued – and that is the fact that 90% of living species have exchangedkissesandbacteriain addition to the alterations of intestinal flora and the skin that characterize inflammatory diseases of the skin and intestines.”

We are made of bacteria!

The experiment was conducted in two phases.In the second, the 21 participating couples were given aprobiotic at the start of the experiment.This allowed for a more reliable count to be collected after 10 seconds ofkissing. Which was key in order to ascertain the identity of the oral bacterial species after the kiss.Bacteria play a fundamental role in the biological approval process.

“Just think – continues – that each of us has morebacteriathan cells, and there are crowded colonies in flux, especially those that are the gateways to the outside: the mouth and gastrointestinal tract in particular.”

The general opinion that bacteria is dangerous should be understood more clearly, dropping the unscientific notion that “all bacteria is bad bacteria.”

“Fortunately, scientific research is increasingly producing new and complex discoveries. However, it has yet to decipher the complex difference between the bacteriathat live in us and diseases. Imbalances can be harmful most notably with the emergence of autoimmune diseases. For instance, excessive hygiene is a factor that exposes the body, especially the skin, to damage rather than greater security.”
