Can a strain of a STD be used to prove that 2 people had sexual contact. in cases such as sexual assault?

Yes, sometimes. But you have to have access to a DNA typing facility that is equipped to handle bacterial or viral DNA.

Nope... Either person could have caught it from somewhere else.

You will need DNA evidence.

probably bacteria has dna

I don't think so... who to say you didn't have it first.

No.

In cases such as sexual assult, DNA is really the only "Evidence" you've got.

When I was interning for my city's crime lab a few years ago...I saw a case where a woman had been raped and killed and the only evidence left was the killers DNA but they couldn't match the DNA to anyone because her killer had never been in trouble before (trouble requiring the state to have a DNA sample).

Anyway, bottom line. No.

No. It is too likely that it was coincidental. It is very difficult with most STD's to determine if they are specific to an individual. Herpes, for all intents and purposes, is herpes. It would be very difficult to say someone has the same herpes as someone else.

Lots of people could have that strain so it is not conclusive. DNA is.
Can come from hair,saliva, skin cell etc. but hospital would have done that if you went there after incident.

Very doubtful. I am in the medical field, and we have never used strains to link people together. The reason simply is that there are so many people affected by various strains of STDS, the most common being Chlamydia (gonorrhea is 4 times less in incidence).

Have you ever seen that educational poster, where if one person has slept with so and so they've actually slepy with all these other people? Well one strain of gonorrhea, for example, could be on two people, yes, but it could have come from one source...those two people may have not even met! Thus, it is by no means clear evidence of contact, especially in such serious cases of accusation of sexual assault.

Why not - sick as it may be. If the scumbag committed the offense he should be locked up.

It might be considered Circumstantial Evidence and if there were enough little details to back up a report this might be considered damaging...especially if she had recently had a full physical and could prove that she was not sexually active at the time.

Now the only question is why would you want to know...if you're a man?

It's quite possible.

No you have to have a lot more to prove assault
bruises DNA hand marks their blood that's why if you have been assaulted call 911 or go to the hospital it very important even though very embarrassing if you call the police (if you don't the hospital will) they have special women who will talk to you and god don't shower
Sorry more info than asked for
