From Lyme to Alpha-Gal

0% played% buffered

Tick-borne diseases are extremely widespread, but they seem to be difficult to diagnose and hard to treat. Science has now recognized many more conditions that result from tick bites than were known even a decade ago.

Lyme Disease:

The diagnosis and treatment of Lyme disease, caused by Borrelia burgdorferi and transmitted by a deer tick bite, remains surprisingly controversial. (See the CDC’s latest update here.) Some experts are skeptical that Lyme disease can linger and cause chronic inflammation and suffering. We talk with a doctor who had trouble getting his colleagues to acknowledge his own Lyme infection. After years of untreated infection, the Borrelia destroyed his heart and he needed a transplant.


We also discuss the common co-occurrence of other infections that can be transmitted by ticks, along with or instead of Lyme disease. Our guest, a rheumatologist, has worked with a veterinarian who developed a diagnostic test for Bartonella. What are the symptoms of this infection, and how can it be treated?

Alpha-Gal Allergy:

We complete our update with another look at alpha-gal allergy. This reaction to the bite of a lone star tick results in cross reactivity to mammalian meat. Eating bacon, a hamburger or a lamb chop could result in a serious situation of hives, wheezing or a trip to the emergency department several hours later. What should you know about alpha-gal?
