Thank you, Mr. Sternthal.
As well, it's great to have Dr. Lindsay here with us.
I want to follow up on the state of knowledge. We heard from the people who were here the other day from the Lyme Disease Foundation that multiple strains of Borrelia seem to be involved.
There was a comment earlier that burgdorferi was the causative agent, but they felt there was a range of other strains of Borrelia that seemed to be causing symptoms as well, and maybe that's why our diagnostic tests were not so accurate.
Can you comment on the state of knowledge regarding which strains or multiple strains might be involved in the infection?
