This is a small sample, only 12 hamsters. So, that doesnt mean it cant happen 1 out of 1000. Or that humans may have more abrasions or whatever that may make transmission in humans different.
But, that said, this is a real actual study. And, they could not find evidence of transmission.
I would love to see other studies if anyone has seen them, not just speculation.
Investigation of venereal, transplacental, and contact transmission of the Lyme disease spirochete, Borrelia burgdorferi, in Syrian hamsters.
Woodrum JE, Oliver JH Jr.
Institute of Arthropodology and Parasitology, Department of Biology, Georgia Southern University, Statesboro 30460, USA.
A hamster was inoculated with the SI-1 strain of Borrelia burgdorferi and subsequently served as a host to larval Ixodes scapularis Say. Approximately 68% of the nymphs resulting from the fed larvae were infected. Nymphs from this group were fed on uninfected hamsters, and 3 of 4 males and 6 of 6 females became infected. The infected hamsters were allowed to mate with uninfected partners to test for venereal transmission. Six infected females were mated with 6 uninfected males, whereas 3 infected males were mated with 6 uninfected females. None of the uninfected hamsters became infected after mating. Two protocols were used to determine if transplacental transmission of B. burgdorferi occurred. One group included 6 nonpregnant infected females that were subsequently mated and became pregnant. Three of the females were allowed to carry to full term, whereas the other 3 were killed prior to parturition. All fetuses and offspring were negative for B. burgdorferi based on cultures and monoclonal antibody assays. Another group of 6 females was infected via tick bite after becoming pregnant; those females were allowed to carry fetuses to birth and all were negative. Attempts at contact transmission of B. burgdorferi from 2 infected females to 2 uninfected male and 2 uninfected female hamsters and from 2 infected males to 2 uninfected male and uninfected female hamsters via urine or feces failed.

My thoughts on this. All of the babies showed up negative for Lyme, we know how much a negative result means, little to nothing. Plenty of human babies end up with Lyme who's only exposure to the infection is from their mother. My kids seemed entirely normal for at least the first 5 years of their lives. They then started showing some signs of problems and by the time they were in their early teens, I knew something was wrong.
Also, hampsters, don't live very long, approx. 3, maybe up to 5 years. They might not even live long enough to show any symptoms. Many of these little guys were killed early, sickening!!! Often it takes Lyme years if not decades to make itself manifest. It may spend long periods in a dormant stage.
So, it is nice that they are at least looking, but you need to understand the nature of Lyme a little more then they apparently do. Posts: 1251 | From california | Registered: Apr 2005

Thanks for posting this, although I don't give this study much credibility.
As to the sexual transfer, unless there is much more to this story, it does not appear that the infected animals were tested to determine whether or not live Bb forms were present in their semen or vaginal fluid. I believe that information is critical.
Without those tests done prior to sexual contact, what does this study prove? Nothing, as I see it.
I'm not sure about the "casual contact" type study or the transplacental study. I have concerns along the same lines as my comment on the sexual transmission part of the study.
