Those who think that love is the听only 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 Research听succeeded to count the听bacteria听jumping from tongue to tongue and published on听惭颈肠谤辞产颈辞尘别听a study that revealed incredible results: 80 million bacteria and 700 different strains are exchanged with each kiss!
No worries, though.听It is a gift that is generally harmless.听
“In fact – says , Head of听Rheumatology and Clinical Immunology听at听麻豆传媒AV在线看听– if the听kiss听is part of our set of social behaviour from the beginning of time,听surely there must be some secret in this evolutionary gesture. There might be an explanation for the exchange of听bacteria.”
However, the scientific community is not yet able to provide a definitive account on the phenomenon.
“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 exchanged听kisses听and听bacteria听in 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.听In the second, the 21 participating couples were given a听probiotic at the start of the experiment.听This allowed for a more reliable count to be collected after 10 seconds of听kissing. Which was key in order to ascertain the identity of the oral bacterial species after the kiss.听Bacteria play a fundamental role in the biological approval process.
“Just think – continues – that each of us has more听bacteria听than 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 鈥渁ll bacteria is bad bacteria.鈥�
“Fortunately, scientific research is increasingly producing new and complex discoveries. However, it has yet to decipher the complex difference between the bacteria听that 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.”
