No matter how fleeting the encounter, the DNA will hang around in their mouth for at least an hour. First, avoid kissing people you dont know. The question that many researchers continue to ask is: what impact does bacterial content from saliva have on sequencing? Quantification based on fluorescence such as Picogreen or Qubit provides an accurate measurement of DNA within a saliva sample. It is a component of virtually every cell in the human body. In addition, finger swabs (in the case of digital penetration) could also be collected from the suspect. Weve clearly demonstrated that when performing sequencing the bacterial content has no impact on variant calling. Your immune system creates antibodies during an infection to fight off the virus that caused it. However, several factors can affect the DNA left at a crime scene, including environmental factors (e.g., heat, sunlight, moisture, bacteria, and mold). 2(3): e305 (2007).

"We've shown it's possible to get a full profile, which could be useful in crime investigation to pinpoint the possible perpetrator among suspects or exclude those innocent," Kamodyov told New Scientist. It all has to do with the composition of saliva. With the advent of more sensitive typing methodologies, it became common-place to also examine fingernail clippings for foreign DNA as well as swabs collected from areas on the victim's body where the suspect was said to have kissed, licked, or bitten the victim.
