Dutch researchers unveiled that a kiss can transfer millions of germs in just 10 seconds.  In this study, the researchers talked about passionate kisses instead of the ordinary kiss.

The researchers examined 21 couples between the ages of 17 to 45. They asked the participants of experiment to drink a probiotic juice before they kiss. Later on, the experts requested them to wash their mouths in a special container. Afterwards, researchers closely examined the saliva and water of their mouths.The study reveals that the even a short kiss of 10 seconds can transfer 80 million germs.

Remco Kort, the lead author of the study stated that intimate kissing begins with the contact of the tongue. Nowadays, it is pretty common in all types of cultures.

Moreover, Kort informed that couples who were emotionally attached to each other, share more germs as compared to the strangers. The primary reason behind the difference in the ratio of committed and unrelated people is the use of specific toothpaste or smoking.

In the entire research, the experts concentrated on lactobacillus and Bifidobacteria. These two kinds of bacteria unite together to form almost 0.15 percent of the germs in human saliva.

On the other hand, a new study reveals that mouth germs merely play a small role in the health of human being. The mouth of an ordinary person contains nearly 700 types of bacteria, whereas the body is a house for more than 100 trillion microorganisms. The main function of these microorganisms is to fight with other small bacteria.
