Kaye,
Nobody has any idea.
The only data on sperm came from a Chinese study on transmissibility of intra-cellular mycobacteria.
In general I would not expect the transmission to be terribly easy, but whereas some leading Lyme doctors still maintain that borrelia can only be spread by ticks, I am not quite that sanguine when it comes to the L-forms of the many species involved in these Th1 diseases (borrelia, rickettsia, mycobacteria and many others...)
But there is no proof of transmissibility - it is all guesswork at this point...
Kaye says, "...is it possible that someone with a cold sore on there month could transfer bacteria to someone through oral sex and than that person get shingles."
If a person has a herpes sore on their mouth, (commonly called a cold sore) this means they have HHV1, or Human Herpes Virus 1. This is highly transmissable, so yes, someone could "catch" it, but this is different than a bacterial infection.
Shingles is caused by another herpes virus, Herpes Zoster, which commonly causes chicken pox in children. When this virus is "re-inactivated" in an adult, it commonly triggers a case of shingles.
Oftentimes, when an immune system is weakened or compromised, an adult will have this reactivation of this virus, if they had chicken pox as a child, rather than "getting it" from someone else.
