The Risk of Getting Infected With Lyme Disease in the Bedroom

The Risk of Getting Infected With Lyme Disease in the Bedroom

Research gathered by a group of international scientists was presented at the annual Western Regional Meeting of the American Federation for Medical Research.

The study was conducted by an esteemed group of researchers and the abstract was published in the January 2014 issue of the Journal of Investigative Medicine.  The following was reported by Online PR News following a presentation made in Carmel, California.

Lyme disease is a tickborne infection caused by Borrelia burgdorferi, a type of corkscrew-shaped bacteria known as a spirochete (pronounced spiro’keet). The Lyme spirochete resembles the agent of syphilis, long recognized as the epitome of sexually transmitted diseases.

Last summer the Centers for Disease Control and Prevention (CDC) announced that Lyme disease is much more common than previously thought, with over 300,000 new cases diagnosed each year in the United States. That makes Lyme disease almost twice as common as breast cancer and six times more common than HIV/AIDS.

“Our findings will change the way Lyme disease is viewed by doctors and patients,” said Marianne Middelveen, lead author of the study presented in Carmel. “It explains why the disease is more common than one would think if only ticks were involved in transmission.”

The present study was a collaborative effort by an international team of scientists. In addition to Middelveen, a veterinary microbiologist from Canada, researchers included molecular biologists Jennie Burke, Augustin Franco and Yean Wang and dermatologist Peter Mayne from Australia working with molecular biologists Eva Sapi and Cheryl Bandoski, family practitioner Hilary Schlinger and internist Raphael Stricker from the United States.

In the study, researchers tested semen samples and vaginal secretions from three groups of patients: control subjects without evidence of Lyme disease, random subjects who tested positive for Lyme disease, and married heterosexual couples engaging in unprotected sex who tested positive for the disease.

As expected, all of the control subjects tested negative for Borrelia burgdorferi in semen samples or vaginal secretions. In contrast, all women with Lyme disease tested positive for Borrelia burgdorferi in vaginal secretions, while about half of the men with Lyme disease tested positive for the Lyme spirochete in semen samples. Furthermore, one of the heterosexual couples with Lyme disease showed identical strains of the Lyme spirochete in their genital secretions.

“The presence of the Lyme spirochete in genital secretions and identical strains in married couples strongly suggests that sexual transmission of the disease occurs,” said Dr. Mayne.

“We don’t yet understand why women with Lyme disease have consistently positive vaginal secretions, whilst semen samples are more variable. Obviously there is more work to be done here.”

Dr. Stricker pointed to the unknown risks of contracting Lyme disease raised by the study.

“There is always some risk of getting Lyme disease from a tick bite in the woods,” he said. “But there may be a bigger risk of getting Lyme disease in the bedroom.”

Dr. Stricker practices medicine in San Franicisco, and is wll known for his cutting-edge approach to treating chronic lyme disease.

Dr. Stricker is also a member of the American Society of Hematology (ASH), the Federation of Clinical Immunology Societies (FOCIS), the International Council on Infertility Information Dissemination (INCIID) and the International Lyme and Associated Diseases Society (ILADS).
